On the Compatibility of Glycolic Acid and BHA Exfoliators
The way of skin care and exfoliation is related to the tenderness of the skin. Glycolic acid and BHA exfoliators are both commonly used in skin care. However, whether they can be used together is worth exploring.

Glycolic acid is a type of fruit acid, which has a small molecule and can penetrate deep into the stratum corneum of the skin, promote the metabolism of keratinocytes, make the skin glow, and is also effective in improving uneven skin tone and reducing fine lines. BHA exfoliators, namely salicylic acid derivatives, are fat-soluble, can penetrate deep into pores, clean dirt in pores, and have significant effects on skin problems such as acne and acne.

If you want to know whether the two are compatible, it is necessary to know the reason of their chemistry and skin action. Glycolic acid is acidic, and BHA is also an acidic substance. Using both may cause local acidity of the skin. The skin has its own acid-base balance, excessive acidification, or damage to the skin barrier, causing skin sensitivity, redness, tingling, etc.

If it is used properly, it is also necessary. If the skin has strong tolerance, when using it for the first time, you can try it in a small amount and low concentration to observe the skin reaction. If you use it with glycolic acid at intervals of several days, after the skin gets used to it, add BHA exfoliator, and strictly control the frequency and dosage of use.

After use, you should also pay attention to skin moisturization and repair. Skin care products containing ceramide, hyaluronic acid and other ingredients can be used to help the skin rebuild its barrier and maintain hydration.

In short, glycolic acid is compatible with BHA exfoliators, which has advantages and disadvantages. Users should carefully observe their own skin condition and act prudently to keep their skin healthy and obtain skin care effects.
