Bakuchiol is extracted from the seeds of Psoralea corylifolia and has been used in Ayurvedic and traditional Chinese medicine for centuries. Its appearance in modern skincare is more recent – and the reason it’s credible isn’t the traditional use, it’s that it demonstrably activates the same gene pathways as retinol without binding retinoid receptors.
A 2014 study by Chaudhuri and Bojanowski identified that bakuchiol upregulates collagen types I, III, and IV, reduces MMP expression (the enzymes that break down collagen), and regulates genes involved in cell proliferation and apoptosis – the same downstream effects as retinoids, via a different receptor mechanism. A 2018 randomised controlled trial published in the British Journal of Dermatology compared 0.5% bakuchiol twice daily against 0.5% retinol once daily and found comparable reductions in wrinkle surface area and hyperpigmentation, with significantly less scaling, stinging, and burning reported in the bakuchiol group.
The practical implication: bakuchiol gives you retinol-adjacent results without the adjustment period, photosensitivity concerns, or irritation that makes retinol challenging for some skin types. It’s stable in light and can be used morning or evening. It doesn’t require the cautious ramp-up protocol that retinol does.
It’s also one of the few evidence-backed options during pregnancy, where retinoids are contraindicated. This isn’t a minor niche – it fills a genuine gap.
0.5-2% is the working range. Below 0.5% the research support is thin. Unlike retinol, bakuchiol has antioxidant and anti-inflammatory properties that are active simultaneously with its retinol-like effects, which may account for some of the tolerance advantage.
