Retinoic Acid

Drug Details

Retinoic acid, a metabolite of vitamin A, plays a crucial role in numerous biological processes, including embryonic development, immune function, and skin health. In the body, vitamin A is converted into retinoic acid through a series of enzymatic reactions. Once formed, retinoic acid binds to specific nuclear receptors, such as retinoic acid receptors (RARs) and retinoid X receptors (RXRs), to regulate gene expression. This regulation influences cell growth, differentiation, and apoptosis. In dermatology, retinoic acid and its derivatives are widely used to treat conditions like acne, psoriasis, and photoaging due to their ability to modulate skin cell behavior. However, excessive levels of retinoic acid can lead to toxicity, underscoring the importance of maintaining appropriate vitamin A intake.
