Summary

Moisturizing Hydrating Antioxidant Anti-aging Barrier Strengthening Soothing Sebum Regulating Firming

Science

Mechanism of Action

This extract deeply moisturizes the skin and helps preserve its natural elasticity by fortifying the skin's protective barrier against environmental aggressors like pollution and UV radiation. It is rich in essential trace elements, including iodine, calcium, and magnesium, which nourish the skin and support its regeneration processes. Bioactive compounds such as fucoidan and polyphenols contribute to its humectant properties, while stimulating collagen synthesis for improved firmness and reduced appearance of fine lines. Additionally, it helps regulate sebum production and provides antioxidant defense against oxidative stress, alongside anti-inflammatory effects attributed to minerals like magnesium and zinc, which soothe redness and irritation.
