Skin Hydra 17D

Multi-Dimensional Moisturizing Solution with 17 Molecular Structures

17D Sodium Hyaluronate Solution is a next-generation ingredient composed of more than 17 types of hyaluronic acid with different molecular weights. From ultra-low to high molecular weight, each type contributes uniquely: high molecular weights form a protective film on the skin’s surface, mid-range molecules fill the moisture in the middle layer, and low molecular weights penetrate deeper to enhance elasticity. Additionally, with the combination of hyaluronic acid derivatives and cross-linked polymers, this ingredient maintains stable formulations and delivers a multi-layered, customized hydration effect.

03 Anti-inflammatory & Soothing Effect
Alleviates irritation caused by external pollutants and fine dust and helps suppress inflammatory responses.
