Valuable CAS - / SKIN CONDITIONING

Antioxidant Skin-Restoring Soothing Moisturizer / Humectant Skin-Barrier Enhancing

Science

This ferment extract operates through several mechanisms to enhance skin health and appearance. It acts as a natural source of postbiotics, supporting a balanced skin microbiome by encouraging beneficial bacterial growth and inhibiting harmful microorganisms. It strengthens the skin's natural barrier, which in turn stimulates skin regeneration and promotes cellular renewal, leading to improved texture. The ingredient functions as a potent soothing agent, effectively reducing redness and irritation, while also forming a protective shield against environmental pollutants. Its humectant properties ensure deep hydration, enhancing the skin's moisture retention capacity, elasticity, and overall healthy appearance. Furthermore, it possesses significant antioxidant capabilities, neutralizing free radicals, combating signs of aging, and reducing inflammation. It also contributes to increased collagen and hyaluronic acid production for smoother, plumper skin, may help reduce acne and blemishes, and can inhibit melanin production to prevent skin discoloration, supporting increased glycosaminoglycan levels for improved facial volume.
