Regarding the application sequence of glycolic acid and hyaluronic acid
in the way of skin maintenance, glycolic acid (Glycolic Acid) and hyaluronic acid (Hyaluronic Acid) are both commonly used. However, the order of application of the two is related to the effectiveness of maintenance and cannot be ignored.

Glycolic acid is a type of fruit acid and has the ability to exfoliate. It can loosen the connection between keratin cells, make old keratin fall off, make the skin surface smooth and delicate, and can stimulate the production of collagen and improve the metabolism of the skin. However, it has a certain irritation, if the skin is sensitive or uncomfortable.

Hyaluronic acid is famous for moisturizing, which can absorb thousands of times its own moisture, replenish moisture for the skin, enhance skin hydration, and make the skin full and elastic.

If glycolic acid is applied first, then hyaluronic acid. After exfoliation with glycolic acid, the stratum corneum of the skin becomes thinner. At this time, hyaluronic acid is more likely to penetrate into the deep layer of the skin and exert its moisturizing effect. And it can relieve the dryness problem that may occur after exfoliation with glycolic acid. However, this order requires the skin to tolerate the stimulation of glycolic acid. If the skin is sensitive, apply glycolic acid first or cause redness, tingling and other discomfort.

On the contrary, if hyaluronic acid is applied first, a moisturizing film can be formed on the surface of the skin to provide certain protection for the skin. Later, glycolic acid can reduce its irritation to the skin. However, this order may affect the exfoliation effect of glycolic acid, because the moisturizing film of hyaluronic acid may hinder the contact between glycolic acid and keratinocytes.

Therefore, if you want to determine the order of application of the two, it depends on the individual skin type. For those with strong skin tolerance, glycolic acid can be used first and then hyaluronic acid to achieve the dual effects of exfoliation and moisturizing; for those with sensitive skin, hyaluronic acid should be used first for skin protection, and then glycolic acid should be used, and attention should be paid to the In short, by choosing the right application sequence according to the skin type, the two effects can complement each other and achieve the beauty of the skin.
