Expert Verdict
🔴 Cyanogenic glycoside — enzymatic or acidic hydrolysis releases hydrogen cyanide (HCN). This is a significant toxicological concern. Present naturally in bitter almonds, cherry pits, and Prunus bark. Intentional use as an isolated cosmetic ingredient is highly inadvisable without rigorous safety assessment demonstrating that no HCN liberation occurs under use conditions.
