Summary

Moisturizing Skin Conditioning Anti-inflammatory Antioxidant Barrier Strengthening Regenerative Skin Tone Enhancing Anti-aging Penetration Enhancer

Science

Mechanism of Action

This extract primarily functions as a potent humectant and emollient, deeply moisturizing the skin by enhancing water retention. Its abundance of essential fatty acids, including oleic and linoleic acids, along with vitamins A and E, and various antioxidants, reinforces the skin's natural barrier. This action leads to improved firmness and elasticity, while its anti-inflammatory properties effectively calm dry, irritated skin, reducing redness and puffiness. Furthermore, it supports cellular energy and regeneration, which refines skin tone and texture, and diminishes the appearance of fine lines. It also acts as a penetration enhancer, aiding the delivery of other active ingredients into deeper skin layers.
