The combination of glycolic acid and salicylic acid
causes skin diseases, whether it is prickly or rough and dull, and everyone wants to solve it. The combination of glycolic acid and salicylic acid is quite important to physicians and beauty lovers.

Glycolic acid belongs to alpha-hydroxy acid. Its molecules are small and can penetrate the stratum corneum of the skin, loosen the adhesion between keratinocytes, and make the old keratin fall off, so that the skin can be renewed. And it can promote the synthesis of collagen and hyaluronic acid in the dermis, making the skin moist and elastic, and fine lines gradually disappear.

Salicylic acid is a beta-hydroxy acid. With lipophilic properties, it can penetrate deep into pores, remove oil, dredge blockages, and has significant effect on the prevention and treatment of acne. It can also be anti-inflammatory and reduce swelling, and relieve redness, swelling and pain of the skin.

The combination of the two complements each other. Glycolic acid rejuvenates on the surface of the skin, and salicylic acid penetrates deep into the pores to clear obstructions. When used together, it is effective in improving skin quality, removing acne and marks, anti-aging and anti-wrinkle, etc.

When used together, it should also be cautious. Skin is different, and tolerance is different. For beginners, it should be tried on a small scale first, and the skin should be observed. And the starting concentration should be low and gradually increase. If the skin feels uncomfortable, such as tingling, redness, desquamation, stop using it immediately, or consult a doctor.

In short, the combination of glycolic acid and salicylic acid, if used properly, can help the skin's health and beauty, but it must not be reckless, and it must be based on prudence.
