The Ordinary Advanced Retinoid 2% - a stable emulsion of next-generation forms of retinoid. This formulation combines two forms of next-generation retinoid actives in a combined concentration of 2% by weight. These two actives are: - Solubilized Hydroxypinacolone Retinoate is a highly-advanced form of retinoid which is, in fact, a non-prescription ester of all-trans direct retinoic acid that offers a multi-fold better effect against signs of ageing than retinol, retinyl palmitate and nearly all other forms of non-prescription retinoid; - A sustained-delivery form of pure retinol in a protective capsule system which supports both the delivery and the effect of Solubilized Hydroxypinacolone Retinoate. Both forms of retinoid used avoid the irritation associated with retinoid (including retinol) use while delivering better visible results against signs of ageing. Alcohol-free, nut-free, vegan, gluten-free, soy-free.
