Science

Mechanism of Action

This extract operates via multiple pathways to enhance skin vitality. Its rich profile of phytochemical compounds, vitamins (A, B, C, E), minerals, and amino acids confers potent antioxidant capabilities, effectively neutralizing free radicals and protecting skin from environmental stressors. It supports the skin's moisture barrier, improving hydration and potentially modulating sebum synthesis to benefit dry skin. Additionally, it exhibits anti-inflammatory and soothing effects, aiding in the reduction of redness. General watermelon extracts, including seed components, are known to support collagen synthesis for improved skin elasticity and possess DNA-protecting properties against UV damage, with in-vivo studies on fruit extract demonstrating up to a 25% increase in skin protection.
