Analysis of the Mixed Use of Salicylic Acid and Glycolic Acid
The use of chemical acids is becoming more and more widespread. Among them, salicylic acid and glycolic acid have different effects, but the advantages and disadvantages of mixing are different, and need to be explored in detail.

Salicylic acid has fat-soluble characteristics, can penetrate deep into the hair follicles, clean the oil and dirt in the pores, and has anti-inflammatory properties. It is often favored by acne muscles to treat acne and other diseases. Glycolic acid is water-soluble and is a kind of fruit acid. Its molecules are tiny and can quickly penetrate the surface of the skin, promote keratin metabolism, make the skin delicate and smooth, and improve the dullness of the skin tone.

If the two are mixed, it may theoretically be possible to achieve both. Salicylic acid clears pores and glycolic acid rejuvenates the skin, which seems to achieve a better skin beauty effect. However, in actual operation, caution is required. Both are irritating to a certain extent, and mixed use may cause skin intolerance. In light cases, the skin may feel tight, red, and tingling; in severe cases, it may cause allergies, such as rash, itching, and even affect the skin barrier, causing moisture loss and skin sensitivity.

When mixed, concentration control is crucial. For beginners, low-concentration products, such as 2% salicylic acid and 5% glycolic acid, should be selected. And the frequency of use should be sparse, try it every few days to observe the skin's reaction. If the skin adapts well, then adjust it as appropriate. The order of use is also exquisite. Generally, salicylic acid is used first, and after it dries, glycolic acid is used, which may reduce irritation.

Furthermore, during the mixed use period, sun protection is indispensable. Because both make the skin more sensitive to ultraviolet rays, if there is no sun protection, it is easy to cause sunburn, tanning, and accelerate skin aging.

In short, the combination of salicylic acid and glycolic acid may have the potential to beautify the skin, but risks coexist. Users must carefully observe the characteristics of the skin and be cautious in order to seek advantages and avoid disadvantages and benefit the skin.
