Science
Mechanism of Action
Palmaria Palmata Powder primarily acts as a humectant through its rich polysaccharide content, attracting and retaining moisture while forming a protective film. Its antioxidant efficacy stems from polyphenols, sulfated polysaccharides, and vitamins (A, C, E), neutralizing environmental stressors and supporting collagen production for anti-aging effects. Additionally, it calms irritation with anti-inflammatory properties and enhances skin radiance by improving circulation and reducing hyperpigmentation, all while providing essential minerals and B vitamins for cellular rejuvenation.
