ULVA PERTUSA EXTRACT.

Valuable / BLEACHING

Ulva Pertusa Extract, derived from green seaweed, is a multi-functional marine ingredient. It provides robust antioxidant protection and calms inflammation. Critically, it directly supports skin structure by inhibiting collagen degradation while also enhancing hydration and improving skin texture.

Summary

Antioxidant Anti-inflammatory Hydrating Collagen Support Skin Conditioning

Science

Mechanism of Action

This extract operates via several biological pathways to enhance skin health. It actively scavenges free radicals, providing potent antioxidant defense against environmental stressors like pollution and UV radiation, thereby mitigating visible signs of aging. Its anti-inflammatory action helps to reduce skin redness, irritation, and itchiness, fostering a calmer complexion. Ulva Pertusa Extract directly inhibits matrix metalloproteinase-1 (MMP-1), an enzyme responsible for type I collagen degradation, thus supporting the preservation of skin's structural integrity. Furthermore, its rich composition of hydrating compounds, including alginates and polysaccharides, contributes to enhanced moisture retention and improved hydration levels. The extract is also a source of vitamins A, C, and E, which further support its skin-conditioning benefits.
