PGA Provide Long-lasting Moisturizing Effect

Experiments from Department of Cosmetic Science,Providence University confirm that,PGA and the Hydrogel Moisturizer provides long-lasting effect to skin moisture,especially under hot dry place or under cold dry winter weather conditions.

Fig.2 PGA Hydrogel with active ingredients synergistically enhances the moisturization effect of skin cream.

Data from:Department of Cosmetic Science,Providence University.

Fig.2 shows that: Adding PGA Hydrogel into the skin lotion generally improves over 27% of moisturization to the skin;PGA Hydrogel also brings up more than 45% of moisturization of total active ingredients.

Data from: Degussa, Germany 

Tests from DEGUSSA (Germany) confirm that,PGA is a real long-lasting moisturizing and skin care product.γ-PGA and the hydrogel forms smooth,elastic,moisturizing soft film on the skin.It enhances skins smoothness,reduces skins wrinkles and improves skins firmness and elasticity.

PGA  Enhance the Skin Health 

Effectively promote the N.M.F inside the skin

The side chain of PGA has strong hydra ability,which can improve the skin moisture without break the skin moisture balance inside and outside.Used in skin-care products,PGA can strengthen the dry skin moisturizing effect or prevent normal skin from dry.

γ-PGA can increase the production of the Natural Moisturizing Factor (N.M.F) such as pyrrolidone carboxylic acid (PCA),lactic acid and urocanic acid (UCA),So as to enhance the skin internal moisturizing ability.

 Brighter, smoother, softer

Inhibition on Melanin Biosynthesis

     Besides a powerful moisturizing capability,PGA also can whiten skin by controlling melanin synthesis to prevent and reduce wrinkles and freckles.

As shown in table 2,PGA has good skin whitening effect,more than 50% of the results of equivalent kojic acid or vitamin C.
