Hydroxypinacolone Retinoate is a derivative of retinoic acid. It is actually retinoic acid + pinacol.
This is a very popular ingredient. It not only has a small molecular weight, is easily absorbed through the skin, has low irritation to the skin, but also has a direct effect. It has obvious advantages over other types of retinoids.
The characteristic of its working mechanism is that it does not need to be converted into retinoic acid in the body, but directly binds to the relevant receptors to exert its effect.
