Bakuchiol

Also known as: Psoralea corylifolia extract, babchi

Bakuchiol is a plant-derived compound marketed as natural retinol, and it has more legitimate data than most botanical trends: it activates retinoid-like gene expression without being a retinoid, and a randomized, double-blind, head-to-head trial found it matched 0.5% retinol on wrinkles and pigment with less irritation. That said, the entire clinical literature is a handful of small studies. A 2024 review of 15 human trials found 12 were unblinded and uncontrolled, so comparable-to-retinol currently rests mainly on one 44-person, 12-week study.

How it works

Bakuchiol has no structural resemblance to retinoids, but in gene-expression studies it switches on many of the same skin targets retinol does, upregulating collagen-related genes. It is also an antioxidant with anti-inflammatory and antibacterial activity, and unlike retinol it is photostable and does not trigger the classic retinoid irritation pathway.

What the evidence says, claim by claim

These are the results measured in studies, not the results shown in ads. Where the research is weak, the grade says so.

For wrinkles and fine lines

Limited evidence

In the key RCT, 44 patients used bakuchiol 0.5% twice daily or retinol 0.5% nightly for 12 weeks: both significantly reduced wrinkle surface area with no statistical difference between them, and bakuchiol users reported less scaling and stinging. A 2022 systematic review found consistent improvements in photodamage and wrinkle scores across the small clinical literature. One adequately designed comparative trial is promising but not yet strong evidence.

Only small, short, or lower-quality studies exist. Treat marketing claims about this use with caution.

For dark spots and hyperpigmentation

Limited evidence

The same 12-week RCT found bakuchiol significantly reduced hyperpigmentation, equal to retinol 0.5%, with dermatologist grading blinded to treatment. Supporting studies in the 2022 systematic review also reported pigment improvements, but most used bakuchiol blended with other actives, making its solo contribution hard to isolate.

Only small, short, or lower-quality studies exist. Treat marketing claims about this use with caution.

For acne

Not enough evidence

Bakuchiol is sold in acne lines on the strength of its antibacterial and anti-inflammatory lab profile, but human data are minimal. A 2024 systematic review of 15 human bakuchiol trials, which included acne studies, found 12 of 15 were unblinded open-label studies without a control group. There is no vehicle-controlled RCT establishing bakuchiol as an acne treatment.

The marketing has moved faster than the research. There is no good human data behind this use yet.

Risks and what can go wrong

Well tolerated in trials, with less scaling and stinging than retinol in the head-to-head study; occasional contact dermatitis has been reported. It is often suggested as the retinoid alternative for pregnancy because it is not a retinoid, but no pregnancy safety studies exist, so that is an assumption of safety, not evidence of it. Its source plant contains psoralens (compounds that can cause light reactions), though purified bakuchiol itself is photostable.

The practical details

OTC only, typically 0.5 to 2% in serums and creams. Twice-daily use matches the trial protocol, and it can be used morning and night since it is photostable. Reasonable for people who cannot tolerate retinoids or want to avoid them while pregnant or nursing, with the caveat that its evidence base is roughly one good trial deep. Results in the RCT appeared over 12 weeks.
