PGA-Hy (Polyglutamic Acid Hydrogel)
INCI Name: Polyglutamic Acid/Aqua
Multi-dimensional water locking, long-lasting moisturizing and smooth skin feeling
Aiming at moisturizing, the most fundamental pursuit of skin care, PGA-Hy is a hydrogel of PGA produced by cross-linking using patent technology. PGA-Hy has three dimensional net structures which can absorb 1000~2000 times as much water as the structures on dry weight basis. PGA-Hy can form a protective film on skin to lock water and produce smooth skin, as well as relieving the oxidation stress of skin.
Multi-dimensional water locking and long-lasting moisturizing
PGA-Hy forms a protective film on skin to inhibit water evaporation. The net structures of PGA-Hy, like a reservoir, absorb so big an amount of water that water can always be replenished for skin in time.
Put different samples on the surface of skin model. Check the moisture content of the skin models regularly and calculate the water retention ratio. The result shows the sample containing PGA-Hy has excellent moisturizing capability with the water retention ratio much higher than the blank sample.
Refreshed and smooth feeling
According to the volunteers, PGA-Hy brings wonderful skin feeling and performs well in each index. The most notable are not oily, not viscous and excellent refreshed and smooth feeling.
Anti-oxidation
Excessive oxidative stress is the most important reason for skin aging. Oxidative stress leads to the generation of excessive free radicals including hydroxyl radicals and superoxide anions. PGA-Hy can effectively clear those substances and relieve oxidative stress of skin to prevent aging of skin.
