When using skin care products, the order of use of glycolic acid (Glycolic Acid) and moisturizer is crucial. As a fruit acid, glycolic acid has unique effects and characteristics, and its correct use is related to skin care effect and skin health.

If glycolic acid is used first, it has strong penetration and can effectively remove aging keratin on the surface of the skin, unclog pores, and make it easier for the skin to absorb nutrients in subsequent skin care products. After using glycolic acid, after a period of time, after it fully functions and is absorbed by the skin, apply a moisturizer, which can replenish moisture and nutrients to the skin in time, lock in skin moisture, avoid skin moisture loss due to the exfoliation of glycolic acid, and keep the skin hydrated.

On the contrary, if the moisturizer is applied first, the protective film formed on the surface of the skin may hinder the effective contact of glycolic acid with the skin, affecting the exfoliation and improvement of skin quality of glycolic acid. Moreover, if glycolic acid is used after the moisturizer, it may cause excessive product superposition, increase the burden on the skin, and cause discomfort, such as tingling, redness, etc.

In summary, it is usually recommended to use glycolic acid first, wait for it to act on the skin for a period of time, about 10 to 15 minutes, and then use the moisturizer. However, it should be noted that everyone's skin condition is different. People with sensitive skin should perform a local skin test before using glycolic acid to confirm that there are no adverse reactions before using it normally, and the frequency of use should not be too high to avoid damage to the skin. In this way, you can reasonably arrange the order of use of glycolic acid and moisturizer according to your skin type to achieve the ideal skin care effect.
