2. Antioxidant & Repair:   It acts as an antioxidant, protecting cells from free radical damage, and promotes DNA repair, contributing to overall cellular health.

3. Anti-inflammatory Action:   It can modulate inflammatory responses, reducing skin inflammation and helping to soothe the skin.

4. Promotes Wound Healing:   It accelerates the wound healing process by attracting immune cells and fibroblasts to the injury site and promoting tissue regeneration.

5. Enhances Barrier Function:   It helps strengthen the skin's barrier, improving moisture retention and resistance to external irritants.
