Is hyaluronic acid filler and hydration hyaluronic acid the same thing?

"Everyone has heard of hyaluronic acid, and it is found in face masks, skin care products, and facial fillers. It not only moisturizes and locks in moisture, but also corrects contours and replenishes facial volume loss. That's also called hyaluronic acid, is hyaluronic acid for filling and hyaluronic acid for hydration the same thing ?" Qiu Yongbi, vice president of the non-invasive department of plastic and cosmetic hospital, said that hyaluronic acid, also known as hyaluronic acid, naturally exists in human skin.

It is like a dry sponge ball without water, it has a strong ability to absorb water and lock water, and if the hyaluronic acid content in the skin is reduced, the moisturizing function of the skin will be greatly weakened, appearing rough and wrinkled. But there is a certain difference between the hyaluronic acid used for hydration and the hyaluronic acid used for filling, and the hyaluronic acid used for moisturizing and hydrating alone cannot play the role of shaping and filling. Hyaluronic acid is a hinge product, and its molecular size depends on the amount of hinge.

The difference between large molecules and small molecules, the first is the rate of degradation, and the degradability of large molecules is often slower and longer than that of small molecules. The second is the effect, large molecules are usually used for superficial filling, while small molecules can be deeply filled. The difference between the two is that the degree of cross-linking is different, and the degree of crosslinking will affect the elasticity and metabolic time of hyaluronic acid. The main component of the mask and skinbooster is non-crosslinked hyaluronic acid, which can be metabolized by the human body after subcutaneous injection for about a week, so it cannot be used as a filling material. The hyaluronic acid that can be used to fill and shape is added with a cross-linking agent, and after changing from liquid to gel, the hardness and viscosity of hyaluronic acid are improved, and the molding and support will become better.
