When performing skin care steps, the order of use of hyaluronic acid (Hyaluronic Acid) and glycolic acid (Glycolic Acid) is quite critical.

Generally speaking, glycolic acid, as a fruit acid, has a certain exfoliating effect, which can promote the aging of the skin surface to shed, making the skin smoother and more delicate. However, it may also make the skin more sensitive and thin.

Hyaluronic acid is known for its powerful moisturizing function, which can grab and lock in a lot of moisture, replenish moisture to the skin, and maintain the skin's hydrated state.

In view of the possible irritation of glycolic acid to the skin, it is generally recommended to use hyaluronic acid first. In this way, a moisturizing film can be formed on the surface of the skin to provide certain protection for the skin and reduce the possible irritation caused by subsequent use of glycolic acid. After that, glycolic acid is used to exert its exfoliation and other effects on the basis of ensuring skin moisture, achieving a more gentle and effective skin care process.

If glycolic acid is used first, the skin may become more fragile after exfoliation. At this time, if there is no pre-moisturizing protection of hyaluronic acid, dryness, redness and other discomforts are more likely to occur. Therefore, in skin care procedures, the order of hyaluronic acid first and then glycolic acid is more appropriate, which helps to achieve good skin care results and care for skin health.
