Bakuchiol is a meroterpene phenol derived from the seeds and leaves of Psoralea corylifolia — a plant used in Ayurvedic and traditional Chinese medicine for thousands of years. In modern skincare, it is significant because a randomised controlled trial published in the British Journal of Dermatology in 2018 found that 0.5% bakuchiol twice daily performed comparably to 0.5% retinol once daily for wrinkle reduction, pigmentation improvement, and elasticity — with significantly less irritation, dryness, and photosensitivity.
The 2018 Dhaliwal et al. study in the British Journal of Dermatology is the key reference here. In this 12-week double-blind randomised trial, 44 subjects used either 0.5% bakuchiol twice daily or 0.5% retinol once daily. The results were:
This does not mean bakuchiol is equally potent to retinol at all concentrations — rather, at 0.5%, twice-daily bakuchiol matched once-daily 0.5% retinol. Higher retinol concentrations (0.3–1%) have not been directly compared to bakuchiol in published trials. The honest interpretation is: bakuchiol performs in a similar ballpark to moderate retinol, with substantially better tolerability.
Bakuchiol's mechanism is distinct from retinol. It does not convert to retinoic acid — it is not a retinoid at all chemically. Instead, research has shown it upregulates some of the same genes that retinoic acid does, including genes involved in collagen synthesis, and downregulates matrix metalloproteinases (the enzymes that degrade collagen). It also has antioxidant and anti-inflammatory properties that retinoids lack.
Because it does not work through retinoic acid receptors, it avoids the mechanisms responsible for retinoid side effects: irritation, dryness, and photosensitivity. This is what makes it genuinely different from a retinol ester (like retinyl palmitate) — it is not a weaker version of retinol, it is a different molecule that achieves some of the same downstream effects through alternative pathways.
Use at 0.5–1% concentration, morning and evening, after cleansing and before moisturiser. It does not require the gradual introduction that retinol does — you can start using it daily from the outset. It is compatible with all other actives and does not require any specific timing restrictions.
Bakuchiol is not a marketing gimmick. The clinical evidence for it is real, peer-reviewed, and published in a reputable dermatology journal. For sensitive, pregnant, or reactive skin, it is an excellent primary anti-aging active. For everyone else, it can serve as a gentler alternative to retinol or as a complementary AM anti-aging ingredient (while retinol runs PM). The research does not support it replacing high-potency retinoids for those who can tolerate them — but for a very large portion of the population, it is an honest, well-evidenced choice.
