Royal Jelly Extract – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Royal Jelly Extract's status as a "superfood" for the skin is largely due to a unique fatty acid found nowhere else in nature: 10-Hydroxy-2-decenoic acid (10-HDA). In skincare science, 10-HDA is recognized for its ability to support the skin's natural production of lipids and collagen precursors. Unlike standard moisturizers that simply sit on top of the skin, the 10-HDA in Royal Jelly acts as a biological signal, encouraging the skin to reinforce its own moisture barrier from within. This makes it an essential ingredient for "depleted" skin—skin that has lost its natural bounce, appears thin, or struggles to retain moisture even with heavy creams. By providing the building blocks (amino acids) and the signal (10-HDA), Royal Jelly helps transition the skin from a reactive state to a resilient one.
