OENOTHERA ROSEA EXTRACT.

Valuable / ANTIOXIDANT, SKIN PROTECTING

Oenothera Rosea Extract, derived from a species within the Evening Primrose genus, demonstrates distinct antioxidant and anti-inflammatory properties. While specific human skin clinical data for *Oenothera rosea* is currently limited, research on closely related *Oenothera* species suggests broader dermatological benefits including enhanced hydration and anti-aging potential.

Antioxidant Anti-inflammatory Hydration Support Collagen Production Support Skin Elasticity Improvement Soothing

Science

Mechanism of Action

Oenothera rosea extract functions primarily through radical scavenging, exhibiting notable antioxidant and anti-inflammatory activities. Insights from *Oenothera biennis*, a related species, suggest that extracts can significantly boost skin hydration by increasing hyaluronic acid levels and upregulating key moisturizing genes, such as HAS2 and AQP3. Furthermore, these extracts may improve skin elasticity and support skin regeneration by inhibiting matrix metalloproteinases (MMPs) and stimulating type I collagen production.
