Science

Lactobacillus/Evening Primrose Seed Ferment Extract Filtrate is produced through the controlled fermentation of Oenothera biennis (Evening Primrose) seeds by Lactobacillus bacteria. This fermentation process is understood to break down complex molecules into smaller, more bioavailable constituents, which may facilitate improved absorption into the skin. Functioning primarily as a skin conditioning agent, it is believed to contribute to the balance and integrity of the skin's microbiome and support a robust epidermal barrier. Evening Primrose is notably rich in linoleic acid (LA) and γ-linolenic acid (GLA), essential fatty acids that are crucial for fortifying the skin barrier, regulating trans-epidermal water loss, promoting cellular regeneration, and enhancing skin smoothness. The overall effect includes soothing, moisturizing, antioxidant benefits, and potential improvements in skin elasticity, alongside anti-inflammatory properties.
