Royal jelly extract is a bee-derived ingredient rich in proteins, fatty acids, vitamins, and the unique compound 10-hydroxy-2-decenoic acid (10-HDA), used in skincare for its proposed moisturizing, antioxidant, and anti-aging effects. Evidence in topical applications is limited, with most data derived from in vitro and preliminary studies.
