• Different ways of use

Hyaluronic acid is injected under the skin by professional doctors to fill in depressions, remove wrinkles and facial contouring; whereas cosmetic hyaluronic acid, due to its low content, is only applied externally to the surface of the skin, and is easily lost.

• Different beauty benefits

The Beauty Benefits of Hyaluronic Acid in Skin Care Products:  The main effect is to lock water and moisturise the skin. It can only stay in the surface layer of the skin, playing a protective and slight repair function.

Injectable hyaluronic acid cosmetic effect: The role of injectable hyaluronic acid is more extensive, and it can be used for wrinkle removal, shaping and moisturising, and the effect is immediate.

• Different content
  

There is a big difference in the concentration of hyaluronic acid for injection and the hyaluronic acid in beauty and skin care products. The purity of hyaluronic acid in hyaluronic acid for injection is very high; while the content of hyaluronic acid in skin care products is very low.

• Different molecular content

The molecular weight of injected hyaluronic acid is large, which is the key to determine that it must be injected and has a filling effect. The molecular weight of hyaluronic acid in cosmetics is only 1% of that of injected hyaluronic acid, and it is only used to apply on the skin surface.

• Differences in maintenance time

Hyaluronic acid exists in the dermal tissue of human skin and is responsible for storing water and promoting the metabolism of the epidermis. After 25 years of age, the body's own hyaluronic acid will be rapidly lost, and exogenous hyaluronic acid can retain water and nutrients in the skin, but it will still be slowly absorbed by the body metabolism; and injections of hyaluronic acid can generally be maintained for 6-12 months, cosmetic hyaluronic acid need to be coated for a long period of time, the maintenance of time is shorter.
