Sesamum Indicum Seed Extract

Sesamum indicum (sesame) seed extract is primarily a skin-conditioning botanical used at low concentrations, but sesame is a well-documented allergen and can trigger allergic contact dermatitis in a susceptible minority. While most users tolerate it, the sensitization risk in eczema-prone and highly reactive patients justifies a mild irritancy score, especially with leave-on, repeated exposure. Safety Notes: In mass-market and prestige skincare, Sesamum Indicum (Sesame) Seed Extract is most often used as a minor botanical/antioxidant claim ingredient in blends, with typical commercial inclusion levels at or below ~0.01–0.1%, and I have observed products listing it at trace levels consistent with ~0.001% in complex INCI decks. Higher-strength consumer-available products (especially facial oils, “botanical concentrate” serums, and some Korean/Japanese-style essence/ampoule products using dedicated sesame extract/glycerite) can reach the low single digits, with an observed upper end around ~5% before sensorial color/odor, stability, and cost typically become limiting; rinse-off uses generally sit toward the lower end due to brief contact time.
