On the use of glycolic acid in combination with AHA and BHA
for skin care, many methods are mixed, and the application of chemical acids is becoming more and more widespread. Glycolic acid belongs to the family of α-hydroxy acids (AHA), which is very effective in rejuvenating and rejuvenating the skin. However, many beauty lovers often have doubts: Glycolic acid can be used in combination with AHA and BHA?

Glycolic acid, its molecule is delicate, can quickly penetrate the surface of the skin, loosen the connection between keratinocytes, promote keratin renewal, and make the skin delicate and smooth. The AHA family, many of which have this effect, such as lactic acid, malic acid, etc., can gently exfoliate and increase skin luster. For BHA, salicylic acid is the main one, and its lipophilicity is good. It can enter the depths of pores, clear oil, and relieve acne.

From the perspective of chemical properties, glycolic acid belongs to the same category as AHA, and when used together, its exfoliation power is superimposed. If the skin has strong tolerance and is used in moderation, it may have a better skin rejuvenation effect. However, those with delicate skin may be unable to withstand its force, causing skin redness, tingling, and dryness. Therefore, before using it, it is time to carefully observe the skin's tolerance. You can try it before a small area of skin, such as behind the ear or inside the forearm, to see if there is any discomfort.

As for the combination of glycolic acid and BHA, although the mechanism of action of the two is different, one can rejuvenate the skin on the surface, and the other can penetrate deep into the pores to clean. However, both have certain irritation. When using the combination, you must weigh carefully. Use low-concentration products first, gradually increase the concentration and frequency of use, and pay attention to the skin's reaction. If the skin is allergic or uncomfortable, you should stop using them immediately.

In general, glycolic acid must be used in combination with AHA and BHA, but it needs to be used with caution according to the characteristics of the individual skin. Only by using it in moderation can you enjoy the benefits of acid and avoid its harm during skin care, and achieve a smooth and smooth skin.
