What is the effect of hyaluronic acid injection on the face?

1. Moisturizing

The hyaluronic acid molecule contains a lot of carboxyl and hydroxyl groups, so it has a strong ability to bind water, and it is especially moisturizing when used on the skin, and the larger the molecule, the better the moisturizing performance. One of the advantages of it over other moisturizers is its intelligent moisturizing ability. It has a particularly strong ability to absorb moisture in low humidity, but it will not absorb too much water and cause moisture in high humidity.

2. Wrinkle removal and shaping

After hyaluronic acid penetrates into the skin, in addition to providing moisture to the inner cells of the skin, it can also fill in the intercellular space for a filling effect, making the skin look fuller from the outside. From this point of view, it can also be said to have an anti-wrinkle effect. The smaller the molecular weight, the stronger the anti-wrinkle ability. When you see names such as hydrolyzed hyaluronic acid, super hyaluronic acid, and mini hyaluronic acid, you are talking about this type of small molecule anti-wrinkle hyaluronic acid.

3. Promote wound healing

If the skin is damaged, high molecular weight hyaluronic acid forms a film on the surface of the skin, blocking the invasion of foreign bacteria, dust, and ultraviolet rays, and protecting the skin from damage. It is then degraded into low molecular weight hyaluronic acid by hyaluronidase to provide a temporary matrix for the migration of inflammatory cells and fibroblasts. Then it can combine with fibrin and extracellular matrix proteins to form complexes to promote the formation of granulation tissue and accelerate wound healing. The larger the molecule, the stronger the ability to repair and promote healing.
