What is the difference between injectable hyaluronic acid and topical hyaluronic acid

The difference between injectable hyaluronic acid and topical hyaluronic acid

1. Different concentrations

The hyaluronic acid stock solution used for medical injection is a medicine, while the hyaluronic acid contained in cosmetics is a beauty product, and its concentration varies greatly. Generally, cosmetics advertised as containing hyaluronic acid have a very low content.

2. Different methods of use

Hyaluronic acid injection is injected subcutaneously by a professional doctor to fill depressions and wrinkle moisturizing; due to the low content of hyaluronic acid in cosmetics, it is only applied externally to the epidermis, which cannot really penetrate deep into the skin to achieve the effect, and more ingredients are metabolized.

Three, the effect is different

Cosmetic hyaluronic acid is generally advertised for skin rejuvenation, moisturizing and wrinkle removal, while injection of hyaluronic acid is more widely used and can be used for filling, shaping, and wrinkle removal. Once injected into the skin, the effect is immediate.

Fourth, the maintenance time is different

Hyaluronic acid is composed of a very fine molecule, and has good biocompatibility. At the same time, it can retain the moisture in the skin, but it will be metabolized by the human body. The injection of hyaluronic acid generally lasts for 6-12 months.
