The Analysis of the Combination of Glycolic Acid and Lactic Acid
On whether glycolic acid and lactic acid can be used together. Glycolic acid is an alpha-hydroxy acid, and its molecules contain hydroxyl and carboxyl groups. This acid is used in many fields. In the skin care industry, it is often used because of its ability to exfoliate and increase skin radiance. It can promote the exfoliation of old skin on the surface of the skin, make the skin regenerate, and because of its small molecule, it is easy to penetrate into the deep layers of the skin and help improve skin quality.

Lactic acid is also an alpha-hydroxy acid. It is widely present in nature and also participates in human metabolic processes. In the field of skin care, lactic acid has a moisturizing effect, which can retain moisture in the skin and make the skin moist. At the same time, it also has a slight exfoliation function, which can make the skin surface smooth.

If glycolic acid is used in combination with lactic acid, it should be handled with caution. Both have the ability to exfoliate, and the combined use may enhance this effect. When used in moderation, it can better improve the rough and dull state of the skin, making the skin more delicate and shiny. However, if used in combination, it may cause skin irritation. Due to excessive exfoliation, the skin barrier may be damaged, resulting in redness, tingling, dryness, etc.

When using the combination of the two agents, when choosing according to your own skin condition. Those with strong skin tolerance can moderately try a combination of the two at a low concentration to observe the skin's reaction. For initial use, the frequency should be low. After the skin adapts, the frequency and concentration of use should be adjusted. For sensitive skin, it is recommended to try it on the local skin before use, and it can be officially used without discomfort, and close attention must be paid to skin changes during use.

In summary, glycolic acid and lactic acid can be used in combination. When using them together, it is necessary to weigh the advantages and disadvantages and use them reasonably according to their own skin characteristics to achieve the best effect of skin care and protect skin health.
