TL;DR
Bakuchiol works, but not as well as retinol on the things retinol is best at. The famous 2018 Dhaliwal trial showed comparable wrinkle and pigmentation results at twelve weeks, but on a small sample, with limitations the headlines glossed over. For pregnancy, breastfeeding, or genuinely retinoid-intolerant skin, bakuchiol is the right call. For everyone else, retinol still has the deeper evidence base.
The bakuchiol story is one viral study away from being completely overhyped, and that’s roughly where we are. The Dhaliwal et al. 2018 paper turned a relatively obscure botanical into a global skincare ingredient, brands rushed to formulate around it, and the marketing copy started claiming retinol-level results without retinol-level evidence. The reality is gentler. Bakuchiol is useful. It is not interchangeable with retinol.
What bakuchiol actually is
A meroterpene extracted from the seeds of Psoralea corylifolia, used in Ayurvedic medicine for centuries before Western skincare picked it up. The relevant mechanism is that it activates the retinoid receptor pathway, the same family retinoic acid binds to, without being structurally a retinoid. So it triggers some of the same downstream collagen-signalling and pigment-regulation effects, but without the vitamin A backbone, the photo-instability, or the typical retinoid side effects.
The interesting part for pregnancy and breastfeeding readers: it operates through retinoid pathways without being a retinoid, which is why dermatologists generally consider it pregnancy-acceptable. See pregnancy-safe skincare.
What the Dhaliwal study showed
The 2018 British Journal of Dermatology paper compared 0.5% bakuchiol twice daily with 0.5% retinol once daily over twelve weeks, on 44 patients. Both arms showed statistically significant reductions in wrinkle depth and hyperpigmentation. Bakuchiol caused less scaling and stinging.
What the headlines glossed over. The sample is small. The bakuchiol arm was used twice daily and retinol once daily, so it’s not a strict dose-matched comparison. Twelve weeks is short for retinol; the bigger collagen-density effects in tretinoin trials take six to twelve months to fully land. And no follow-up trial at scale has replicated the result with quite the same effect size.
What other studies have shown
Smaller trials and ex-vivo work generally find bakuchiol effective at 0.5% to 1% over twelve to sixteen weeks for fine lines, modest pigmentation improvement, and elasticity. The effect size is usually around half to two-thirds what retinol delivers in matched conditions.
Sensitivity tolerance is consistently better. Real-world dropout rates on bakuchiol products are far lower than on 0.3% retinol or higher, because skin doesn’t peel and sting the same way.
The contrarian: bakuchiol is the better intro retinoid for nervous skin
The framing “bakuchiol vs retinol” is the wrong frame. The right frame is bakuchiol as the bridge: the first retinoid-pathway active for readers who have never used anti-ageing actives, who are scared of irritation, who have abandoned retinol three times because of peeling. Twelve weeks of bakuchiol stabilises the receptor pathway, primes skin tolerance, and makes a follow-on transition to 0.2% retinol vastly easier.
This is the use case the marketing doesn’t capture because “bakuchiol is the bridge to retinol” is less catchy than “bakuchiol replaces retinol.” But it’s the way I’d actually advise a new reader to use it. See retinol vs bakuchiol for the longer comparison.
Real numbers, one citation
Dhaliwal S et al., “Prospective, randomized, double-blind assessment of topical bakuchiol and retinol for facial photoaging,” British Journal of Dermatology, 2019 (publication delayed from 2018 conference data). 44 patients, twelve weeks. Wrinkle surface area decreased by approximately 20% in both groups; bakuchiol arm reported fewer cases of scaling (around 10% vs around 25%). Hyperpigmentation reduction was 5 to 8 percent across both arms, statistically equivalent. The single trial is real and the effect is real; what’s missing is the multi-decade evidence base retinol has.
Who bakuchiol suits
Pregnant and breastfeeding readers, hands down. Genuinely retinoid-intolerant skin that has failed three retinol introductions. Sensitive readers who want anti-ageing benefit without irritation. Readers in their late twenties to early thirties starting a preventative active. Combination skin types who can’t tolerate retinol’s drying effect.
Where it underperforms: significant photoageing, deeper fine lines, acne treatment (where retinoids regulate sebum and turnover in ways bakuchiol doesn’t), and severe pigmentation issues. There, the evidence still favours retinol.
How to use it
0.5% to 1% in a serum or moisturiser. Once or twice daily. AM or PM, though PM is the convention. Photo-stable, so no special pairing rules. Plays well with vitamin C, niacinamide, peptides, hyaluronic acid, ceramides, sunscreen. Doesn’t have a specific irritation-aware on-ramp the way retinol does; you can start daily without easing in.
If you want full retinoid-pathway benefit with the gentle entry, layer a peptide cream on top. Our BioCell Renewal Cream works for that pairing.
The honest framing
Bakuchiol is useful in a specific set of cases. It is the right ingredient for some readers and the wrong one for others. It is not a retinol replacement in any general sense; it is a retinoid-adjacent active with a softer profile, smaller effect, and a real role in pregnancy and intolerance contexts.
Buying it expecting tretinoin results in twelve weeks is the path to disappointment. Buying it expecting gentle, slow improvement over four months is realistic and reasonable.
FAQ
Can I switch from retinol to bakuchiol? Yes, especially in pregnancy. Expect a smaller effect size.
Can I use bakuchiol and retinol together? You can. The receptor pathways overlap, so the marginal benefit is small, but irritation often drops compared to retinol alone.
How long until I see results? Twelve to sixteen weeks for visible change. Faster than peptides, slower than retinol.
Is bakuchiol safe during pregnancy? Generally yes. Confirm with your obstetrician.
What concentration should I look for? 0.5% to 1% is the studied range. Below 0.5% is mostly marketing.
