Science

LACTOBACILLUS/EVENING PRIMROSE SEED FERMENT FILTRATE functions by releasing a rich array of beneficial compounds, including amino acids, peptides, organic acids such as lactic acid, enzymes, and antioxidants directly to the skin. This complex supports multiple facets of skin health: promoting cellular repair, enhancing hydration, and fostering overall resilience while maintaining a healthy skin pH. It significantly strengthens the skin barrier, reduces transepidermal water loss, and provides a calming effect, thereby alleviating irritation and inflammation. Furthermore, its humectant properties draw and retain moisture, while its antioxidant activity offers protection against oxidative stress and environmental aggressors. The ingredient also contributes to a balanced skin microbiome by encouraging beneficial bacteria, reinforcing the skin's natural defenses. The Evening Primrose components specifically supply linoleic acid (LA) and γ-linolenic acid (GLA), essential fatty acids known to be precursors to anti-inflammatory eicosanoids, improve skin's water balance, further fortify the epidermal barrier, and support skin regeneration for a smoother texture.

These ingredients are composed of bacterial fermentation byproducts rather than live microorganisms. While generally considered safe and non-toxic, individuals with sensitive skin may experience allergic reactions, necessitating a preliminary patch test.
