In Foods ( oral grade HA supplements):
√ Enhance the skin's water retention function, smoothing, delicate and elastic skin;
√ Delay skin aging;
√ Improve joint lubrication and reducing joint pain;
In Cosmetics:
√ Skin nutrition
Pure hyaluronic acid powder can enrich its content in the skin.Low molecular HA can infiltrate directly into the dermis, to achieve the function of the skin nutrition.
√ Moisturizing
It can form hydration film on the surface of the skin, soften the cutin layer of hydration, make skin soft and smooth and delicate.
√ Thickening
It has thickening and stable effect in the cosmetics.
