On the method of mixing glycolic acid and salicylic acid
There is a method of skin care in the world. It is related to the mixture of glycolic acid (Glycolic Acid) and salicylic acid (BHA), and people often wonder if it can be done. Both of these are good skin care agents, but their properties are different.

Glycolic acid, a type of fruit acid, has tiny molecules, can quickly penetrate the surface of the skin, exfoliate significantly, rejuvenate the skin, promote cell renewal, and make the skin smooth and delicate. Salicylic acid is a fat-soluble acid, which can penetrate deep into the pores, remove oil, antibacterial and anti-inflammatory, and is especially good for dealing with skin diseases such as acne and acne.

If you want to mix the two, you must be careful. Check the skin's tolerance first. If the skin is delicate and sensitive, if it is mixed rashly, it may cause discomfort, such as redness, tingling, and itching. Therefore, at the beginning, it is advisable to try it on a small scale to observe the skin's reaction. You can apply a small amount of the mixture behind the ear or under the chin first, and wait for a few hours. If there is no abnormality, it can be gradually used on the face.

When mixing, control its concentration. The concentration of glycolic acid is too high, although the effect is obvious quickly, it is also irritating; the same is true for salicylic acid. Usually, a low concentration of glycolic acid is 2% - 5%, and salicylic acid is 0.5% - 2%. The two are properly matched to complement each other. If the concentration is out of balance, it will not only be difficult to obtain the effect of skin care, but also damage the skin.

Furthermore, the frequency of use cannot be ignored. When using it for the first time, the frequency should be low, such as once or twice a week. Wait for the skin to adapt, and then increase the number of times. And when using it, you need to avoid sunlight, because after mixing, the skin's sensitivity to light may rise, which is easy to cause sunburn and pigmentation.

In short, mixing glycolic acid and salicylic acid, if you follow the rules of concentration, frequency and sun protection according to the nature of the skin, can be a wonderful way for skin care and help the skin regain its luster. However, if you are not careful, there will be drawbacks, which cannot be ignored.
