On the synergistic effect of glycolic acid and salicylic acid
The way of skin management, glycolic acid (Glycolic Acid) and salicylic acid (BHA) are used together, and their functions are quite different. Glycolic acid belongs to alpha-hydroxy acid, with small molecules, which can quickly penetrate the stratum corneum of the skin. It can loosen the bond between keratinocytes, make old waste keratin fall off, make the skin surface smooth and radiant. And it can promote the regeneration of collagen in the dermis, making the skin firm and elastic.

Salicylic acid, which is a beta-hydroxy acid, has lipophilic properties. It can penetrate deep into the pores, remove the oil, dirt and keratin accumulated in the pores, smooth the pores, and prevent the growth of acne and acne. For inflamed skin, it is more soothing, reducing redness and swelling.

The two work together, glycolic acid works from the surface of the skin to improve the appearance of the skin; salicylic acid goes deep into the pores to purify. One table and one inside, complement each other. For skin rejuvenation, it is far better than using it alone. It should also be used cautiously, because they are all irritating. For those with delicate skin, it is recommended to try it on a small scale first, and gradually increase the dosage and frequency. And after use, heavy sun protection is required to avoid damage to the skin due to light sensitivity.

In short, the rational use of glycolic acid and salicylic acid synergy can open up a new path for healthy and radiant skin, but practitioners should use scientific methods and caution.
