Topical Minoxidil for Skin Rejuvenation

Evidence Review created on 07/30/2026 using AI4L / Opus 4.8

Also known as: Minoxidil, Rogaine, Regaine, 2,4-diamino-6-piperidinopyrimidine 3-oxide

Motivation

Topical minoxidil is a liquid or foam that is rubbed into the skin, best known as a nonprescription treatment for thinning hair. The same drug relaxes the small blood vessels beneath the skin and appears to nudge skin cells into making more of the stretchy fibers that keep skin springy. That combination has raised a question well beyond hair: could the same product help skin itself look firmer, smoother, and younger?

Minoxidil began as a tablet for stubborn high blood pressure. Doctors noticed it caused extra hair growth, and a skin version soon became a widely used hair product. Later laboratory work showed it can push skin cells to produce more elastin, one of the support proteins lost as skin ages, while also loosening the tight protein scaffolding found in scars. At the same time, some people who use it report puffiness or drier skin, so the overall picture is genuinely mixed.

This review examines what is known about applying minoxidil to the skin to refresh its appearance and structure. It gathers the laboratory findings, the limited human observations, the possible benefits, and the real drawbacks, so the balance of evidence for this off-label use can be seen clearly.

Systematic Reviews

The following systematic reviews and meta-analyses concern minoxidil broadly; none address skin rejuvenation specifically, so the most relevant reviews covering efficacy, skin safety, and systemic safety are listed.

Topical Minoxidil: Systematic Review and Meta-Analysis of Its Efficacy in Androgenetic Alopecia - Gupta & Charrette, 2015

This meta-analysis quantifies topical minoxidil’s established biological activity in skin, confirming it produces measurable, dose-related tissue effects that any rejuvenation claim would build upon.

Allergic Contact Dermatitis to Topical Preparations Containing Minoxidil: A Systematic Review and Individual Participant Data Meta-Analysis - Kiratiwongwan et al., 2025

Directly relevant to any facial or full-skin use, this review pools patient-level data to identify how often minoxidil itself, versus its carrier solvents, triggers skin allergy.

The Effectiveness of Treatments for Androgenetic Alopecia: A Systematic Review and Meta-Analysis - Adil & Godwin, 2017

This review benchmarks minoxidil against other agents, establishing the evidence quality and effect sizes that anchor expectations for any newer, off-label skin use.

Efficacy and Safety of Oral Minoxidil Versus Topical Solution in Androgenetic Alopecia: A Meta-Analysis of Randomized Clinical Trials - Sobral et al., 2025

By comparing routes of delivery, this analysis clarifies how much drug the topical route actually delivers and how its side-effect profile differs, both central to skin dosing.

Low-Dose Oral Minoxidil Does Not Significantly Affect Blood Pressure: A Systematic Review and Meta-Analysis - Chen et al., 2025

This meta-analysis addresses the main systemic safety worry, showing that at low systemic exposures the drug’s blood-pressure effect is negligible, reassuring for the far smaller amounts absorbed through skin.

Mechanism of Action

Minoxidil is a prodrug: it becomes active only after skin and liver enzymes called sulfotransferases (chiefly SULT1A1, an enzyme that attaches a sulfate group to compounds) convert it into minoxidil sulfate. The active form opens ATP-sensitive potassium channels (K-ATP channels, molecular pores in cell membranes that control electrical charge and muscle tone). This relaxes the muscle in small blood-vessel walls, widening the vessels and increasing local blood flow to skin.

Several downstream effects are proposed to matter for skin quality:

Increased blood supply and new vessel growth: Wider vessels and higher output of VEGF (vascular endothelial growth factor, a signal that drives new blood-vessel formation) raise oxygen and nutrient delivery to the dermis, the living layer beneath the surface.
Elastin stimulation: In cultured skin cells, minoxidil raises production of elastin and its precursor tropoelastin, the fibers that let skin stretch and spring back. Because these fibers are progressively lost and damaged in aged and sun-exposed skin, this is the main pro-rejuvenation signal.
Reduced collagen cross-linking: Minoxidil inhibits lysyl hydroxylase (an enzyme that stabilizes and stiffens collagen fibers). This lowers the formation of over-cross-linked collagen, the basis for its study in scarring and fibrosis, where excess stiff collagen is the problem.

Competing mechanistic views exist and pull in opposite directions. Supporting rejuvenation, the elastin and blood-flow effects could plausibly firm and thicken skin. Against it, minoxidil raises prostaglandin E2 (PGE2, a lipid signaling molecule), and higher PGE2 is linked in laboratory work to reduced type I collagen and increased collagen-degrading enzymes — the same pattern seen in aged skin. Whether the elastin gain outweighs the potential collagen loss in living human skin has not been resolved.

Key pharmacological properties: the systemic half-life is roughly 3–4 hours; topical bioavailability is low (about 1–2% of an applied dose reaches circulation); it is not appreciably protein-bound; activation depends on sulfotransferase (SULT1A1); and clearance is mainly by hepatic glucuronidation with renal excretion. It has no meaningful cytochrome P450 (liver drug-metabolizing enzyme) interactions.

Historical Context & Evolution

Minoxidil was developed in the late 1960s and reached the market in the late 1970s as an oral drug (Loniten) for severe, treatment-resistant high blood pressure, working as a powerful vessel-widening agent. Its most striking side effect was hypertrichosis (excessive hair growth) across the body, which redirected the drug’s commercial future.

That side effect became the reason it was reconsidered for skin. A topical solution was formulated to grow scalp hair and received approval as Rogaine (5% for men, 2% for women) in 1988 for pattern hair loss. Separately, in the 1980s researchers such as Pinnell and Murad studied minoxidil’s direct effects on cultured skin fibroblasts and found it altered collagen and elastin handling, prompting interest in fibrotic skin conditions such as scleroderma and keloids.

The skin-rejuvenation idea is the most recent and least mature branch. It grew from the observation that minoxidil stimulates elastin and improves blood flow, combined with newer molecular work on aging markers, and has been amplified by online discussion. When historical research is weighed, the actual findings are informative on their own terms: the fibroblast studies consistently show reduced collagen cross-linking and increased elastin, effects that are real but whose benefit for facial aging remains unproven. Scientific opinion has not settled here; rather than a fixed consensus, there is an open and still-evolving question, with new elastin and prostaglandin data emerging on both sides.

Expected Benefits

All benefits below are searched against clinical, mechanistic, and expert sources. For skin rejuvenation specifically, no high-quality human trials exist, so no benefit reaches the High tier; the grades reflect that most evidence is preclinical or indirect.

Medium 🟩 🟩

Enhanced Cutaneous Microcirculation

Minoxidil is an established vessel-widening agent, and its active form opens potassium channels in small-vessel walls, raising local blood flow and, through VEGF, encouraging new capillary formation in skin. Better perfusion delivers more oxygen and nutrients to the dermis, a plausible contributor to healthier-looking skin. The pharmacological effect itself is well documented across scalp and skin tissue; what remains uncertain is whether improved perfusion translates into visible rejuvenation, since this endpoint has not been measured directly.

Magnitude: Not quantified in available studies.

Low 🟩

Dermal Elastin Stimulation

In cultured skin fibroblasts, minoxidil increases production of elastin and its precursor tropoelastin, the fibers responsible for skin’s stretch and recoil that are degraded in photoaged skin. This is the central rationale for a rejuvenation effect, supported by consistent laboratory findings across species and more recent screens of elastin-promoting compounds in human dermal fibroblasts. The evidence is graded Low because it rests entirely on cell-culture and animal work, with no demonstration that topical use raises elastin in living human skin.

Magnitude: In cultured skin fibroblasts, elastin synthesis roughly doubled; effects on intact human skin are unmeasured.

Softening of Scars and Fibrotic Tissue

By inhibiting lysyl hydroxylase, minoxidil reduces the excessive collagen cross-linking that makes scars, keloids, and fibrotic skin stiff, and this anti-fibrotic action has been explored in scleroderma and internal fibrosis models. For rejuvenation purposes, the same effect could in principle soften textured or scarred skin. Evidence is Low: it is grounded in mechanism and preclinical fibrosis studies rather than controlled cosmetic outcomes.

Magnitude: Not quantified in available studies.

Speculative 🟨

Improved Skin Texture and Firmness

Some users and clinicians describe firmer, smoother skin with topical minoxidil, attributed to the combined blood-flow and elastin effects. There are no controlled studies of facial texture, elasticity, or wrinkle depth, so this rests on mechanism and scattered anecdote only.

Support for Wound and Ulcer Healing

Because minoxidil widens vessels and promotes new capillaries, it has been discussed as an aid to slow-healing wounds and ulcers, an effect that would overlap with skin regeneration. The basis is mechanistic and limited case-level experience rather than robust trials, so any rejuvenation-adjacent benefit here is speculative.

Benefit-Modifying Factors

Sulfotransferase (SULT1A1) activity: Minoxidil must be converted to its active sulfate form by this skin enzyme; people with naturally low activity generate less active drug and are likely to see weaker effects, mirroring the poor-responder pattern seen in hair studies.
Baseline skin condition: Skin that is already heavily photoaged, with substantial elastin loss and thinning, has more theoretical room to benefit from elastin stimulation than youthful skin, though this has not been formally tested.
Sex-based differences: Women absorb and respond differently and are more prone to spread-related hair growth, which can shift the risk-benefit balance; response of skin quality itself has not been shown to differ by sex.
Pre-existing conditions: Fibrotic or scarring skin conditions may be more responsive to the anti-cross-linking effect, while inflamed or barrier-compromised skin may absorb more drug and tolerate it less well.
Age: Older adults at the upper end of the target range have the most age-related elastin and collagen loss, giving the largest potential target for benefit, but also thinner skin that may absorb more drug and be more easily irritated.

Potential Risks & Side Effects

The side-effect profile below is cross-checked against drug references and dermatology literature. Because facial or broad skin application spreads the drug beyond the scalp, local reactions are especially relevant.

High 🟥 🟥 🟥

Allergic and Irritant Contact Dermatitis

Redness, itching, scaling, and dryness at the application site are the most common problems with topical minoxidil. Much of this is driven by the carrier solvent propylene glycol in solution formulations, though pooled patient-level data indicate minoxidil itself is also a frequent allergen; foam formulations omit propylene glycol and are better tolerated. On facial skin the reaction is more visible and can be mistaken for skin damage, but it reverses after stopping.

Magnitude: Itching, redness, or scaling at the application site in roughly 5–7% of users of the 5% solution.

Unwanted Hair Growth (Hypertrichosis)

The drug’s signature effect is stimulation of hair, and when applied to or spread onto the face it can produce unwanted facial or nearby hair, the opposite of a cosmetic goal. This results from direct action on vellus follicles and from low-level local spread. It is more troublesome for women and is the single most likely reason a skin-rejuvenation attempt backfires cosmetically.

Magnitude: Unwanted facial or body hair in roughly 3–5% of users, more common in women.

Medium 🟥 🟥

Facial and Peri-Orbital Fluid Retention

Minoxidil’s vessel and potassium-channel effects promote sodium and water retention, which can cause edema (swelling from fluid buildup), sometimes around the eyes and face. This produces puffiness and under-eye bags that mimic aging or tiredness and are a common reason users believe the drug is aging their skin. It typically resolves within about two weeks of stopping.

Magnitude: Facial or around-the-eye puffiness in up to about 1% of users; usually resolves within roughly two weeks of stopping.

Low 🟥

Systemic Cardiovascular Absorption

A small fraction of applied drug enters the bloodstream, and in theory this could cause a faster heartbeat, fluid retention, or a blood-pressure drop, effects seen with the oral form. At the low amounts absorbed through skin these are uncommon in healthy adults, and pooled data show negligible blood-pressure change at low systemic exposure. Risk rises with broad-area application, broken skin, or pre-existing heart disease.

Magnitude: About 1.4% of an applied topical dose reaches the bloodstream.

Collagen Suppression via Prostaglandin Signaling ⚠️ Conflicted

Minoxidil raises PGE2, and higher PGE2 is linked in laboratory studies to reduced type I collagen and more collagen-degrading enzyme activity, the molecular signature of aged skin. This raises the possibility that the drug could thin rather than rejuvenate skin over time. The evidence is directly conflicted: the same drug increases elastin and softens over-cross-linked collagen, and no human study has shown net collagen loss in intact skin, so the direction of the overall effect is genuinely unresolved.

Magnitude: Not quantified in available studies.

Speculative 🟨

Perceived Accelerated Skin Aging

Online reports describe drier, more lined, or “aged” facial skin during use. Careful analysis suggests these appearances are largely explained by the reversible effects above — fluid retention and contact dermatitis — rather than true structural aging, since they resolve on stopping. A genuine aging effect cannot be fully excluded but has no direct evidence.

Risk-Modifying Factors

Sulfotransferase (SULT1A1) activity: Higher enzyme activity produces more active drug and may raise both benefit and local side effects; lower activity reduces both.
Propylene glycol sensitivity: People sensitive to this common solvent are far more likely to develop contact dermatitis with solution formulations and should consider propylene-glycol-free foam.
Sex-based differences: Women are more prone to unwanted hair growth from spread and are generally advised toward lower concentrations.
Pre-existing conditions: Heart disease, fluid-overload states, or kidney impairment increase the consequence of any systemic absorption; compromised skin barrier increases both absorption and irritation.
Age: Older adults have thinner skin that can absorb more drug and irritate more easily, modestly raising local and systemic risk at the upper end of the target range.

Key Interactions & Contraindications

Other blood-pressure-lowering drugs (e.g., beta-blockers such as metoprolol or atenolol, calcium-channel blockers such as amlodipine, diuretics such as hydrochlorothiazide): Additive lowering of blood pressure is possible if enough minoxidil is absorbed. Severity: caution; consequence: light-headedness or low blood pressure. Mitigation: limit application area and monitor blood pressure if used broadly.
Guanethidine (an older antihypertensive): Combined use with systemic minoxidil can cause severe drops in blood pressure on standing. Severity: absolute contraindication with meaningful systemic exposure; consequence: fainting. Mitigation: avoid the combination.
Nonsteroidal anti-inflammatory drugs (over-the-counter pain relievers such as ibuprofen, naproxen, aspirin): These block prostaglandin production and could blunt the PGE2-dependent part of minoxidil’s action, and can independently promote fluid retention. Severity: monitor; consequence: reduced effect or added swelling.
Topical retinoids (tretinoin) and exfoliating agents: These increase skin penetration of minoxidil, raising both absorption and irritation. Severity: caution; consequence: greater local reaction and systemic uptake. Mitigation: separate application timing and start conservatively.
Other topicals and alcohol-/propylene-glycol-based products: Layering can increase irritation and absorption. Severity: caution; mitigation: avoid stacking on the same area at the same time.
Blood-pressure-lowering supplements (e.g., coenzyme Q10, magnesium, garlic extract, fish oil): If enough minoxidil is absorbed systemically, these may add to its blood-pressure-lowering effect; there are no clinically significant interactions with other common dietary supplements at the low systemic exposure of topical use. Severity: caution; consequence: additive light-headedness or low blood pressure. Mitigation: limit application area, and monitor blood pressure if broad-area use is combined with these supplements.
Populations who should avoid this intervention: People with cardiovascular disease (especially recent heart attack within 90 days, uncontrolled arrhythmia, or heart failure at NYHA Class III–IV, meaning marked limitation or symptoms at rest), pheochromocytoma (an adrenal tumor), significant kidney impairment, and those who are pregnant or breastfeeding should avoid off-label skin use.

Risk Mitigation Strategies

Choose a propylene-glycol-free foam: Because much contact dermatitis is driven by the propylene glycol carrier, using 5% foam rather than solution directly reduces the most common risk — application-site itching, redness, and scaling.
Patch test before facial use: Apply a small amount to a discreet area for several days to detect allergy before treating a larger or visible region, preventing a widespread dermatitis reaction.
Confine to intended area and let it dry fully: Apply sparingly, wash hands immediately, and wait 20–30 minutes (or apply well before bed) so undried drug does not transfer to the face or pillow — this limits unwanted facial hair growth and peri-orbital puffiness.
Use the lowest effective concentration and smallest area: Starting with 2% and a limited surface reduces systemic absorption and its cardiovascular and fluid-retention consequences.
Monitor for swelling and heart symptoms: Watch for facial puffiness, rapid weight gain, or a fast heartbeat, and stop if they appear, since these signal fluid retention or systemic absorption; both typically reverse within about two weeks.
Avoid broken or inflamed skin: Applying only to intact skin limits the greatly increased absorption and irritation that occur through a compromised barrier.

Therapeutic Protocol

There is no validated protocol for using minoxidil to rejuvenate skin; the section below describes how the drug is used in practice and how a cautious off-label skin approach is typically framed, not an endorsed regimen.

Formulation and concentration: Standard products are 2% and 5% solution and 5% foam. For facial or broad skin use, lower-concentration foam is generally preferred to limit irritation and hair-growth spread.
Application pattern: Approved hair use is twice daily; any skin use follows the same once- or twice-daily rhythm applied thinly to the target area. No dose has been established for a skin-quality endpoint.
Best time of day: Timing is not critical for effect, but an evening application should allow full drying well before lying down to prevent transfer to the face and eyes.
Half-life and dosing frequency: The active compound’s short systemic half-life (about 3–4 hours) is why hair regimens use twice-daily dosing; single versus split application to skin has not been studied for rejuvenation, and twice-daily thin layers mirror established practice.
Genetic considerations: Response depends heavily on sulfotransferase (SULT1A1) activity, which converts minoxidil to its active form; low-activity individuals are likely poor responders, and no genetic test is routinely used before skin use.
Sex-based differences: Women are steered toward lower concentrations and careful containment because of greater unwanted-hair risk; there is no evidence that the skin-quality response differs by sex.
Age considerations: Older adults have the most age-related elastin loss but thinner, more absorptive skin, so conservative concentrations and areas are more appropriate at the upper end of the target range.
Baseline factors and conditions: Baseline blood pressure and any fluid-retention tendency, heart disease, or kidney impairment should be weighed before use, as they change how much systemic absorption matters.

Discontinuation & Cycling

Lifelong versus short-term: Any effect of minoxidil is maintained only while it is used; like its hair effects, benefits are not permanent and fade after stopping, so it would be an ongoing rather than a one-time intervention.
Withdrawal effects: There is no true drug-withdrawal syndrome. On stopping, drug-driven changes reverse; for skin, this means reversal of side effects such as puffiness and irritation, and loss of any elastin-related gain.
Tapering: No tapering is medically required because the systemic exposure is low; abrupt discontinuation of topical use is not associated with rebound cardiovascular effects.
Cycling: No cycling schedule has been established or shown to preserve effectiveness for skin; cycling is neither validated nor known to be beneficial here.
Practical reversal note: Users who stop because of facial swelling or dermatitis typically see those effects resolve within about two weeks, a useful marker that the changes were reversible side effects rather than lasting skin change.

Sourcing and Quality

Product type and availability: Minoxidil is sold over the counter as branded (Rogaine, Regaine) and generic 2% and 5% solutions and 5% foam; it is a manufactured drug rather than a supplement, so purity is governed by pharmaceutical standards.
Formulation choice: Foam avoids the propylene glycol solvent linked to most contact dermatitis, making it the preferred base for skin use; solutions deliver drug efficiently but carry the irritant carrier.
Compounded options: Some clinicians and compounding pharmacies prepare customized concentrations or carrier-free vehicles; reputable compounding pharmacies that follow recognized quality standards should be used, since compounded products are not individually reviewed by regulators.
What to look for: Choose products from established manufacturers, confirm the active concentration and full carrier ingredient list, and prefer formulations disclosing propylene-glycol-free bases when irritation is a concern.

Practical Considerations

Time to effect: For its proven hair use, changes take 3–6 months; for skin rejuvenation there is no established timeline because no outcome has been measured, and any elastin effect would likely be gradual and unverified.
Common pitfalls: The frequent mistakes are expecting a facial rejuvenation effect the evidence does not support, letting the product spread and cause unwanted facial hair, and mistaking reversible puffiness or dermatitis for skin damage.
Regulatory status: Minoxidil is approved only for pattern hair loss; all skin-rejuvenation use is off-label and unapproved, meaning it has not been reviewed or sanctioned for this purpose by regulators such as the FDA (the U.S. Food and Drug Administration).
Cost and accessibility: The drug is inexpensive, widely available without a prescription, and easy to obtain, so access and cost are not barriers.

Interaction with Foundational Habits

Sleep: Indirect interaction. The main practical issue is timing: an evening application that has not fully dried can transfer to the face and eyes during sleep, worsening puffiness and unwanted hair, so applications should dry fully before lying down.
Nutrition: Indirect interaction. No specific foods enhance or block minoxidil, though the drug’s fluid-retention tendency makes a lower-sodium diet a sensible pairing to limit swelling; activation depends on the body’s own sulfotransferase rather than on diet.
Exercise: Indirect interaction. Sweating and washing shortly after application can remove drug or spread it; applying after exercise and cleansing, then allowing it to dry, avoids both reduced effect and unwanted spread.
Stress management: No meaningful direct interaction. Minoxidil does not act on stress hormones, and stress reduction neither strengthens nor blunts its skin effects.

Monitoring Protocol & Defining Success

Because skin rejuvenation with minoxidil is unproven and largely cosmetic, monitoring centers on catching side effects and tracking subjective skin change rather than on disease biomarkers. Baseline assessment should be done before starting: record blood pressure, resting heart rate, body weight, and standardized photographs of the target skin, and note any heart or kidney history.

The lab and vital-sign measures below are most relevant when application covers a broad area or when systemic absorption is a concern.

Biomarker	Optimal Functional Range	Why Measure It?	Context/Notes
Blood pressure	<120/80 mmHg	Detect a drop from absorbed drug	mmHg means millimeters of mercury; sit quietly 5 minutes before measuring; conventional “normal” extends to <130/85
Resting heart rate	55–70 bpm	Detect a reflex fast heartbeat from vessel widening	bpm means beats per minute; measure at rest, same time of day
Body weight / ankle circumference	Stable week to week	Flag fluid retention (edema)	A rapid gain of 1–2 kg or new ankle or facial swelling suggests fluid buildup
Skin elasticity (recoil)	Rapid recoil versus own baseline	Track the intended firmness effect	Assessed by pinch-recoil at home or an instrument in clinic; compare against baseline photos rather than a fixed reference

Ongoing monitoring cadence: check blood pressure, heart rate, and weight at about 1 week and 4 weeks after starting, then every 3–6 months while use continues; reassess standardized skin photographs every 3 months.

Qualitative markers of success or trouble:

Skin smoothness and texture
Skin hydration and dryness
Skin firmness and elasticity
Peri-orbital puffiness or under-eye bags
Appearance of unwanted facial or nearby hair
Comfort at the application site (itching, redness, scaling)

Emerging Research

In vitro elastogenesis screening: Recent laboratory work continues to test minoxidil among compounds that boost elastin and extracellular-matrix production in human dermal fibroblasts, refining whether and how strongly it could rebuild the skin’s stretch fibers (Krymchenko et al., 2025). This line could strengthen the rejuvenation case if effects prove robust in human skin models.
Delivery and angiogenesis endpoints: A recruiting trial comparing a topical 2-deoxy-D-ribose hydrogel with minoxidil 5% solution includes tissue VEGF (new-vessel signal) as an outcome (NCT07502976), which may clarify how much minoxidil drives skin blood-vessel growth relative to newer agents.
Systemic-exposure and safety mapping: An ongoing phase 3 study of low-dose minoxidil (NCT05888922) will add data on systemic tolerability that bounds how safely broader skin application could be pursued.
Prostaglandin-collagen question: The unresolved concern that minoxidil raises PGE2 and could reduce collagen, set against its elastin-stimulating effect, is the key area that could weaken the case; longitudinal human skin studies measuring both collagen and elastin are needed and do not yet exist.
Absence of dedicated trials: As of the current date, no registered clinical trial evaluates minoxidil for facial or dermal rejuvenation as a primary aim, so near-term evidence will come from mechanistic and hair-focused studies read across to skin.

Conclusion

Topical minoxidil is a widely available, low-cost skin product proven to grow hair, and interest in using it to refresh skin rests on a real but early idea: it widens tiny blood vessels, improves local blood flow, and, in laboratory dishes, prompts skin cells to make more of the stretchy fibers that keep skin springy. It may also soften the stiff protein scaffolding found in scars. These are the main hoped-for benefits, and none has been confirmed in careful human skin studies.

The drawbacks are more concrete. The most likely problems are skin irritation and rash, unwanted hair where the product spreads, and facial puffiness from fluid retention — the last two of which can make skin look older rather than younger, though they fade after stopping. There is also an unsettled question of whether the drug could lower one of skin’s support proteins over time, pulling against its fiber-building effect.

Overall, the evidence base is thin and mixed, built mainly on cell studies and indirect reasoning rather than trials of skin appearance. The possible gains remain unproven while several of the downsides are well established, leaving this an uncertain and genuinely open use rather than a settled one.
