How it works
Bakuchiol is a meroterpene extracted from the seeds and leaves of Psoralea corylifolia, the babchi plant, and it has become the go-to "gentle retinol alternative" in my practice for a good reason. Despite having no structural resemblance to vitamin A, it upregulates the same collagen-related genes that retinoids target, which translates into firmer, smoother-looking skin over time.
Because it does not bind retinoic acid receptors the way retinol does, it skips the irritation cascade of retinization — there is no forced skin-cell turnover spike, which is why patients tolerate it so much better in the first few weeks.
The evidence
A widely cited 2018 split-face trial found bakuchiol 0.5% twice daily produced improvements in wrinkle depth and pigmentation statistically comparable to retinol 0.5% nightly, but with significantly less scaling and stinging. Additional studies support its antioxidant activity and mild anti-acne effect, though the overall body of evidence remains smaller than retinol's decades of research.
Suitability
- Sensitive and reactive skin: a lower-irritation route to retinoid-like benefits
- Retinoid-intolerant patients: an alternative rather than a direct substitute in efficacy
- Combination skin: pairs well in both AM and PM routines since it is not photo-destabilizing
- Pregnancy-adjacent routines: often chosen as a precaution, though it isn't as rigorously vetted as azelaic acid
Concentration
Most formulations use 0.5%–1%, which is where the comparative trial data sits; I don't see justified benefit in pushing much past 2%. Unlike retinol, it can be used morning or night, and it doesn't require the gradual "buildup" schedule that retinoids do.
Conflicts & combinations
- Can be layered with retinol or retinal for patients chasing extra anti-aging effect, but I usually treat this as belt-and-suspenders rather than essential
- Pairs nicely with niacinamide and hyaluronic acid for a balanced anti-aging routine
- Works well alongside centella asiatica for reactive or barrier-compromised skin
- No known photosensitizing interactions, so daytime use with sunscreen is fine

Is bakuchiol as effective as retinol?
Studies show comparable improvements in wrinkles and pigmentation with less irritation, though the evidence base is still smaller than retinol's.
Can I use bakuchiol during pregnancy?
It's often chosen as a gentler alternative, but data is limited, so treat it with caution and discuss with your doctor.
Can I use bakuchiol and retinol together?
Yes, some routines combine both, though it may increase overall irritation risk for sensitive skin.
Does bakuchiol cause purging or peeling?
Rarely — one of its main appeals is a much lower irritation profile than retinoids.
Can bakuchiol be used in the morning?
Yes, unlike retinol it is stable in sunlight, so morning use under sunscreen is fine.
