6) Treatment of Psoriasis
Retinol is also used for the treatment of psoriasis. It is a skin condition caused by inflammation and speedy growth of skin cells. The rash becomes thick, scaly, and pink or scarlet as the new cells accumulate. Topical retinol helps with the rash by decreasing inflammation and slowing down the proliferation of skin cells. Retinol can irritate the skin, so doctors advise using topical steroids with retinol.
