How It Works

A hybrid molecule that delivers both retinol and retinoic acid via skin esterases. Korean-developed and most popular in K-beauty anti-aging formulations.

Skin esterases split the ester to release one molecule of retinol and one of retinoic acid, providing both immediate (acid) and slow-release (alcohol) signalling.
