It is extracted from the seeds of the Babchi plant (Psoralea corylifolia). Known colloquially as BioRetinol, it shares a similar molecular structure and exhibits comparable effects on the skin as synthetic Retinol. These effects include promoting collagen production, reducing the appearance of fine lines and wrinkles, and improving skin elasticity. It is not irritating or photosensitive, so it can be used by all skin types, including sensitive, pregnant and lactating.
