HYA3 補濕修護精華

HYA3 Serum combines four types of hyaluronic acid (HA) — low, medium, high molecular weight, and crosspolymer—at a total concentration of 3%. This structure addresses hydration across both surface and within the dermis, supporting a plump and hydrated appearance.

Most ""low molecular"" hyaluronic acid in the market remain relatively large (20–30 kDa), limiting their ability to penetrate the skin. We harnessed advanced hydrolysis technology to shrink hyaluronic acid to ~5 kDa, enabling rapid penetration through the stratum corneum into the epidermis and dermis, achieving deep hydration for better skin health.

Paired with HA of 4 different molecular weight, this formula aims to provide instant boost and long-term hydration:

Crosspolymer HA — forms a bio-protective network to reduce water loss while helping defend against PM2.5 and UV damage. It also inhibits hyaluronidase activity, strengthening the skin’s moisture barrier for sustained hydration.

High weight HA — forms a protective layer to reduce transepidermal water loss (TEWL)

Medium weight HA — enhances moisture retention in the stratum corneum for visibly smoother and more supple skin.

Enriched with Panthenol, a proven humectant that attracts natural moisture, HYA3 supports the formation of a protective water shield while repairing barrier structures, reducing sensitivity concerns.
