    What is Retinaldehyde?

    Retinaldehyde, also known as vitamin A aldehyde, is a derivative of retinol after oxidation. It is formed by oxidative cleavage of β-carotene. If it is reduced, retinol cas 68-26-8 can be attained; If oxidized, retinoic acid cas 302-79-4 can be attained. The role of retinoic acid (namely Vitamin A) in skin diseases very extensive, but due to local irritation, its clinical application is limited to some extent. Retinaldehyde is an intermediate metabolite of natural retinoic acid and has similar biological activity as retinoic acid. But the skin is significantly more tolerant to retinoic acid.
