The combination of polyglutamic acid and resveratrol leads the innovation of raw materials

Polyglutamic acid (PGA) of Cosmetic Raw Material, a natural peptide, has emerged in the cosmetics industry in recent years, especially for its excellent moisturizing and anti-aging functions. PGA molecules can firmly lock in moisture, keeping the skin moisturized for a long time. More importantly, it also shows unique potential in whitening. Studies have shown that PGA can help improve uneven skin tone and dullness by regulating skin hydration and improving skin brightness.

Among the many Moisturizing Raw Materials, polyglutamic acid and Hyaluronic Acid are often compared. Both have powerful moisturizing effects, but they differ in actual effects and application scenarios. The comparison between polyglutamic acid and hyaluronic acid (Polyglutamic acid vs hyaluronic acid) is mainly reflected in the differences in their molecular structures and hydration. Hyaluronic acid molecules are smaller and can penetrate deep into the skin layer for hydration, while polyglutamic acid molecules are larger and focus more on locking in moisture on the surface of the skin, providing long-lasting hydration. In addition, polyglutamic acid can also form a protective film on the skin surface, enhance the skin's barrier function, and help reduce water loss.
