Plant extracts

Bakuchiol

A plant compound sold as a gentle retinol alternative. One small head-to-head trial found it matched 0.5% retinol with less irritation; the evidence is thin.

Limited evidenceTypical strength: 0.5-1%

What it is

Bakuchiol comes from the seeds and leaves of the babchi plant (Psoralea corylifolia). It has no structural resemblance to retinoids, but in lab skin models it switched on a similar set of genes, including collagen genes.

The best human study is a 12-week randomized, double-blind trial in 44 adults: 0.5% bakuchiol twice daily and 0.5% retinol once daily reduced wrinkle area and pigmentation about equally, and the retinol group had more scaling and stinging. That is encouraging, but small, short and without a placebo group.

How strong is the evidence?

Limited evidence

One small randomized double-blind comparison with retinol (44 people, 12 weeks, no placebo arm) plus lab work and an uncontrolled case study from the ingredient supplier. Results are promising but unreplicated in large trials; 'as good as retinol' rests on that single trial.

What it's used for, checked

Fine lines and wrinkles

Mixed

Matched 0.5% retinol in one 12-week trial; no large placebo-controlled trials yet.

Uneven pigmentation

Mixed

Improved alongside wrinkles in the same trial.

Retinol alternative for sensitive skin

Holds up

Caused less scaling and stinging than retinol in the trial.

Pregnancy-safe retinol swap

Unproven

Often marketed this way, but it has not been studied in pregnancy; 'not a retinoid' is not the same as 'tested safe'.

Who should be careful

  • No pregnancy safety data exist; ask a clinician before relying on it during pregnancy.
  • Prefer products listing purified bakuchiol over whole babchi seed extracts, which can contain psoralens that make skin more sensitive to sunlight.
  • Gentler than retinol but not irritation-free; patch test first.

  1. Prospective, randomized, double-blind assessment of topical bakuchiol and retinol for facial photoageing.
    Dhaliwal S, Rybak I, Ellis SR, Notay M, Trivedi M, Burney W, et al. · British Journal of Dermatology · 2019 · RCT

    44 adults applied 0.5% bakuchiol cream twice daily or 0.5% retinol cream daily for 12 weeks; both reduced wrinkle surface area and hyperpigmentation with no significant difference, and retinol users reported more scaling and stinging.

  2. Bakuchiol: a retinol-like functional compound revealed by gene expression profiling and clinically proven to have anti-aging effects.
    Chaudhuri RK, Bojanowski K · International Journal of Cosmetic Science · 2014 · Laboratory study + case study

    From the ingredient supplier: bakuchiol produced a gene-expression profile similar to retinol in a skin model and increased collagen production; a 12-week use study without a control group reported improved lines, pigmentation and firmness.
