12 wks Duration of the landmark 2019 RCT comparing bakuchiol to retinol — equivalent improvement in wrinkle area and hyperpigmentation found in both groups
0 Adverse effects reported in the bakuchiol group — versus scaling, erythema, and stinging in the retinol group
2x Daily use possible with bakuchiol (AM and PM), versus retinol which is recommended only at night due to UV instability

What bakuchiol actually is

Bakuchiol is a meroterpene compound extracted from the seeds and leaves of Psoralea corylifolia, a plant used in Ayurvedic and traditional Chinese medicine for centuries. Structurally, it looks nothing like retinol. That's the surprising part: it produces retinol-like effects on the skin without being chemically related to retinoids at all.

A 2014 gene expression study published in the International Journal of Cosmetic Science found that bakuchiol upregulates many of the same genes as retinol, including those involved in collagen synthesis and matrix metalloproteinase regulation. It mimics retinol's downstream effects without binding to the same receptors. That distinction is why it doesn't carry retinol's irritation profile or its pregnancy risks.

The clinical evidence: what it does and doesn't prove

The study most people cite is a 2019 prospective, randomised, double-blind trial by Dhaliwal and Rybak, published in the British Journal of Dermatology. Participants applied either 0.5% bakuchiol twice daily or 0.5% retinol once daily for 12 weeks. Both groups showed significant improvement in wrinkle surface area, hyperpigmentation, firmness, and overall photo-damage. The difference between groups was not statistically significant.

Research note

The same trial reported adverse effects by group: scaling in 20% of retinol users, erythema in 10%, stinging/burning in 20%. The bakuchiol group reported no adverse effects. This tolerability difference is clinically meaningful — people are more likely to continue using products they can tolerate, and the benefits of retinoids are dependent on consistent use over months.

The limitation worth knowing: this was a relatively small trial, and subsequent systematic reviews have flagged methodological concerns across bakuchiol studies generally — variable formulations, limited sample sizes, no standardised outcome measures. The evidence is genuinely promising, not yet conclusive at the level of retinol's decades of data.

That said, retinol itself was not always the gold standard it is now. It accumulated its evidence base over time. Bakuchiol is earlier in that curve — but the biological mechanism is plausible, the tolerability data is clean, and for women who can't use retinol, it's the most evidence-backed alternative available.

Who bakuchiol suits best

Bakuchiol is worth serious consideration if you're in one of three situations: your skin reacts badly to retinol (dryness, peeling, chronic redness); you're pregnant, breastfeeding, or trying to conceive; or you want an active you can use in both morning and evening routines without sun risk.

For most women with normal skin tolerance who aren't pregnant, retinol (or prescription tretinoin) remains the better-evidenced choice. The data behind tretinoin especially — decades of RCTs, FDA-approved indications — is substantially deeper than what exists for bakuchiol.

The honest version: bakuchiol fills a genuine gap. It's not marketing hype dressed up as science. But it works best when matched to the right person — not used instead of retinol by someone who could tolerate retinol just fine.

Practical tip

Look for formulations at 0.5% bakuchiol — the concentration used in clinical trials. Combining it with other well-evidenced ingredients (niacinamide, peptides, SPF) gives you a strong routine without the need to add retinol on top.

🩺

Pregnant or trying to conceive?

While bakuchiol's mechanism of action does not involve retinoic acid receptor binding (the route through which retinoids cause teratogenicity), it has not been formally studied in pregnancy. Dermatologists generally consider it lower-risk than retinol, but the safest approach during pregnancy is to discuss any active skincare ingredient with your midwife or obstetrician.
