On the Compatibility of Glycolic Acid and Ascorbic Acid
Glycolic acid and ascorbic acid are both skin care products, but whether the two can be used together is really doubtful.

Glycolic acid is a fruit acid and the like. It has the ability to exfoliate, which can make the old and waste keratin on the surface of the skin fall off, making the skin rejuvenated and more delicate and smooth. It can promote the metabolism of the skin and help the absorption of subsequent skin care products.

Ascorbic acid, that is, vitamin C, has strong antioxidant properties. It can resist the damage of free radicals to the skin, whiten the skin, lighten spots and remove marks, and can also promote the production of collagen, making the skin firm and elastic.

As for whether the two can be used together, it needs to be considered in detail. Glycolic acid can cause the stratum corneum of the skin to thin and make the skin slightly more sensitive. The acidic properties of ascorbic acid may also irritate the skin. If the two are used together, or the irritation to the skin is superimposed, it will cause redness, tingling, itching and other discomfort to the skin.

However, if the skin has good tolerance, it must not be used together. Use glycolic acid products first. After the skin gets used to it, use skin care products containing ascorbic acid at intervals, and the initial dosage should be small to observe the skin reaction. If there is no adverse reaction to the skin, the dosage and frequency of use can be gradually increased.

In short, if you want to use glycolic acid and ascorbic acid together, you need to clarify your skin characteristics first. For sensitive skin, be careful to prevent skin damage. Even well-tolerated skin should be carefully observed step by step, so as to ensure the effect of skin care and not damage the health of the skin.
