Retinyl hydroxyesters and retinyl oligo-hydroxyesters were prepared using a chemoenzymatic process from retinol and short chain esters of hydroxycarboxylic acids or short chain esters of hydroxycarboxylic acids. The presence of the hydroxyl group on the acid can result in a mixture of esters from various oligomers of the hydroxycarboxylic acid. The retinyl ester products are readily enzymatically hydrolyzed in vitro, which indicates that application to the skin should result in release of the anti-aging ingredient retinol (without the inherent instability and irritation) along with the acid, which, if chosen appropriately, should also have desirable biological effects. This combination should be effective as an anti-aging skin care ingredient.
