Bakuchi's active compound, bakuchiol, is a gentle plant-based alternative to retinol for aging skin. Its strongest support is comfort — smoother texture, softer lines, and more even tone with far less irritation. The evidence base is modest and often industry-funded.

| Marker | Target | Why |
|---|---|---|
| Fine-line / wrinkle score (photo grading) | Downward trend by week 12 | Tracks the core anti-aging outcome |
| Hyperpigmentation / evenness of tone | Visible lightening of spots by week 8–12 | Captures pigment and post-mark response |
| Skin hydration (corneometry) | Increase from baseline (roughly 10–20%) | Reflects barrier and moisture benefit |
| Transepidermal water loss (TEWL) | Stable or decreasing | Indicates an intact or improving barrier |
| Erythema / irritation index | Low and stable; no rising trend | Flags early irritation or sensitization |
Cadence: Baseline, then weeks 4, 8, and 12; thereafter every 3–6 months for maintenance
