10-Hydroxydecenoic acid (10-HDA) is a fatty acid, a characteristic component of bee royal jelly. INCI: 10-Hydroxydecenoic Acid. In a formula it works as a conditioning and soothing component and is credited with a mild antimicrobial and antioxidant action. Claims of a marked skincare effect rest mostly on lab work, and topical clinical data are limited. It is a supporting component rather than a lead active with a proven result. Pregnancy safety. Topical use, low systemic absorption, no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation potential is low. The component is related to bee products, so with an allergy to them it is best introduced cautiously.
