Salicylic acid and azelaic acid are used in combination, and the effect is significant. The two complement each other and play a wonderful effect together.

Salicylic acid has excellent keratolytic power, which can dredge pores, make blocked sebum flow out smoothly, and prevent the growth of acne. It can gently peel off the old keratin on the surface of the skin, making the skin smooth and delicate again, like a new life.

Azelaic acid is not inferior, not only can inhibit the activity of tyrosinase, reduce melanin production, and achieve the effect of whitening light spots; it also has the effect of inhibiting Propionibacterium acne, which helps to improve acne skin.

The combination of the two is like a good medicine for acne skin. It can not only solve the problems of clogged pores and frequent acne, but also take into account whitening and light printing to restore clear and fair skin. However, when using, you need to pay attention to the degree of skin tolerance, starting from a low concentration and a small amount, and gradually increasing the dosage and frequency to ensure skin safety and enjoy the wonders of the two.
