Cucumber peel liquid extract is a potent, water-soluble cosmetic ingredient prized for its anti-inflammatory, cooling, hydrating, and antioxidant properties. It reduces under-eye puffiness, tightens pores, soothes irritation, and repairs skin, making it ideal for toners, creams, serums, and eye circle products, Cucumber peel extract is actually more potent than the pulp that’s where most of the actives live. Here’s how it’s commonly used, especially in cosmetics, skin care, and haircare formulations:
Key Actives in Cucumber Peel
