Bakuchiol: A retinol-like functional compound revealed by gene expression profiling and clinically proven to have anti-aging effects

Chaudhuri, R. K., Bojanowski, K.·2014·International Journal of Cosmetic Science

Abstract

OBJECTIVE: The study was undertaken to compare the skin care related activities of retinol and bakuchiol, a potential alternative to retinoids. Retinol is a pivotal regulator of differentiation and growth of developing as well as adult skin. Retinoic acid is the major physiologically active metabolite of retinol regulating gene expression through retinoic acid receptor - dependant and independent pathways. METHODS: Comparative gene expression profiling of both substances in the EpiDerm FT full thickness skin substitute model was undertaken. Furthermore, type I, III and IV collagen, as well as aquaporin 3 expression was analyzed by ELISA and/or histochemistry in human dermal fibroblasts and/or Epiderm FT skin substitutes. RESULTS: Bakuchiol is a meroterpene phenol abundant in seeds and leaves of the plant Psoralea corylifolia. We present evidence that bakuchiol, having no structural resemblance to retinoids, can function as a functional analogue of retinol. Volcano plots showed great overall similarity of retinol and bakuchiol effects on the gene expression profile. This similarity was confirmed by the side-by-side comparison of the modulation of individual genes, as well as on the protein level by ELISA and histochemistry. Retinol-like functionality was further confirmed for the upregulation of types I and IV collagen in DNA microarray study and also show stimulation of type III collagen in the mature fibroblast model. Bakuchiol was also formulated into a finished skin care product and was tested in clinical case study by twice-a-day facial application. The results showed that, after 12 weeks treatment, significant improvement in lines and wrinkles, pigmentation, elasticity, firmness and overall reduction in photo-damage was observed, without usual retinol therapy-associated undesirable effects. CONCLUSION: Based on these data, we propose that bakuchiol can function as an anti-ageing compound through retinol-like regulation of gene expression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
