Sesamum Indicum (Sesame) Seed Extract

Product Description

Sesamum Indicum (Sesame) Seed Extract is a lipid-rich botanical active derived from sesame seeds, standardized to preserve key bioactive compounds including sesamin, sesamolin, unsaturated fatty acids, and tocopherol-related antioxidant fractions.

It functions as a multi-layer skin barrier support system, primarily enhancing epidermal lipid architecture by promoting keratinocyte lipid differentiation and improving intercellular lipid matrix organization within the stratum corneum.

At the biochemical level, it helps regulate oxidative stress through activation of Nrf2-mediated antioxidant pathways, supporting cellular defense against lipid peroxidation and environmental oxidative damage.

Through combined lipid replenishment and antioxidant modulation, it contributes to improved skin resilience, long-term hydration retention, and enhanced skin surface smoothness and comfort.

It is widely applied in barrier repair, anti-aging, nourishing, and recovery skincare systems, particularly suitable for dry, compromised, sensitive, and lipid-deficient skin conditions requiring structural lipid restoration.
