On the skin, it primarily acts as a skin conditioning agent, a humectant that attracts and retains moisture, and a film-former that contributes to a smooth feel. It also offers soothing effects, improves skin elasticity and firmness, and provides antioxidant protection. Furthermore, it may assist in reducing the appearance of hyperpigmentation, dark spots, skin roughness, and wrinkles, rendering it particularly beneficial for sensitive skin, rosacea, and acne-related inflammation.
