The Compatibility of Glycolic Acid and BHA
Fuglycolic Acid, a fruit acid or the like, is weakly acidic, and plays a role in the metabolism of the skin's keratin, the improvement of water and moisturization, and the smoothness of color. BHA, a derivative of salicylic acid, is also acidic, which can penetrate deep into the pores, exfoliate, inhibit oil, and prevent acne. The two have their own strengths in the field of skin care.

However, whether the two can be used together is really related to the tolerance and effectiveness of the skin. Glycolic acid, with tiny molecules, can quickly penetrate the surface of the skin and promote exfoliation. BHA is fat-soluble and can enter the hair follicle sebaceous glands to clear the pores. If the two are properly compatible, or can have a synergistic effect, the improvement of the skin

However, there is also a risk in applying both. Both are sour, and if used together, the acidity will be superimposed, or the skin irritation will be exacerbated. Light cases are redness and itching, and heavy cases are desquamation and burning. Therefore, before using it, we should carefully examine the characteristics of the skin. Sensitive skin, weak skin membrane, poor tolerance, use both together, it may be difficult to bear, and caution should be taken. And oily and well-tolerated skin may be tried on a small scale, depending on the skin's reaction, and then determine whether it can be used for a long time.

When using it, you should also pay attention to the method. When using it for the first time, the concentration should be low and the frequency should be slow. Such as glycolic acid concentration of 2% - 5%, BHA concentration of 0.5% - 2%, 1 - 2 times a week can be. As the skin adapts, and then adjust the concentration and frequency. And after use, it needs tremendous support for moisture and sun protection to protect the health of the skin.

The combination of glycolic acid and BHA has advantages and disadvantages. Users must carefully observe the skin condition and be cautious in order to avoid harm and promote benefits and achieve the best skin care.
