Use of Glycolic Acid and Salicylic Acid
Fuglycolic Acid and Salicylic Acid are both commonly used acids in skin care. However, the way of use needs to be explored in detail.

Glycolic Acid, a α-hydroxy acid, has small molecules, can quickly penetrate the surface of the skin, has strong exfoliation power, can make the skin tender and smooth, promote collagen growth, and light lines and radiance. However, it is strong in nature, and is easy to cause discomfort for those with thin skin or sensitive skin, such as redness, swelling, and tingling.

Salicylic acid, a β-hydroxy acid, has good lipophilicity, can enter pores, clear oil, inhibit Propionibacterium acne, and treat acne well. It has anti-inflammatory effects and relieves skin inflammation. But it is also irritating, especially at high concentrations.

As for the use of the two, caution must be taken. Although the combination can strengthen the cleaning and skin rejuvenation, it can also stimulate the skin. Thin skin and sensitive skin should be avoided. If you want to try it, try it on a small scale first, without discomfort, and then expand it. And the starting concentration should be low, and the frequency should be sparse. When the skin gets used to it, gradually adjust the concentration and frequency.

After using it, it is better to take strict sun protection, because the skin is sensitive to light at this time, preventing ultraviolet damage and causing pigmentation.

In short, glycolic acid and salicylic acid can be used properly to beautify the skin; if used inadvertently, it will hurt the skin. Therefore, it is necessary to carefully review the skin before use and follow the correct method in order to enjoy its benefits.
