Retinoid acid is derived from which vitamin?

Retinoid acid, also known as all-trans retinoic acid, is a metabolite of Vitamin A. It plays a crucial role in various biological processes, including cell growth, differentiation, and regulation of gene expression. In the field of esthetics, retinoic acid is particularly valued for its effectiveness in treating acne and reducing the appearance of fine lines and wrinkles, due to its ability to promote skin cell turnover and enhance collagen production.

Vitamin A exists in several forms, including retinol and retinal, which are converted in the skin into retinoid acid. This conversion is essential for the compound to exert its beneficial effects on the skin. Understanding the relationship between retinoid acid and Vitamin A is fundamental for estheticians when recommending products or treatments that include retinoid ingredients for skin care.
