ZLEY® HEPES (Hydroxyethylpiperazine Ethane Sulfonic Acid) is a mild and non-irritating ingredient thatcan enhance the penetration of other active ingredients.

It helps to gently soften the stratum corneum, regulate skin pH, and improve overall skin texture. By promoting the removal of aged keratin on the skin surface while maintaining the skin’s optimal pH balance, it supports smoother and more refined skin appearance.

In addition, it assists in reducing UV-induced stimulation of melanocytes, thereby helping to minimize melanin formation and contributing to a brighter-looking complexion.
