Use

Retinoic acid, also known as retinoic acid, is a metabolic intermediate of vitamin A in vivo. It mainly affects the growth of bone and the metabolism of epithelial cells. It can promote the proliferation of epithelial cells and keratinolysis. It is suitable for acne vulgaris, lichen planus (including oral lichen planus), leukoplakia, pityriasis rubra and pityriasis simplex.
