Yes.
Salicylic acid is an extract from the plant willow bark and is a natural anti-inflammatory drug. The commonly used cold medicine aspirin is sodium acetylsalicylate, a derivative of salicylic acid, and sodium para-aminosalicylate (PAS) is a commonly used anti-tuberculosis drug. Salicylic acid is commonly used in dermatology to treat various chronic skin diseases such as acne (pimples), ringworm, etc. Salicylic acid can exfoliate, sterilize, and reduce inflammation, so it is very suitable for treating acne caused by clogged pores. The mainstream international acne products contain salicylic acid, and the concentration is usually 0.5~2.
Salicylic acid has two functions: sterilization (anti-inflammatory) and helping to exfoliate old cuticles. It will be irritating, but the merits outweigh the faults. It is a good thing. The reason why it has the effect of shrinking pores is that after the old cuticles are shed, the pores will not look obvious (the principle of microdermabrasion), but the concentration must be between 1-2 (or 0.5-2? I can’t remember) , salicylic acid will have an exfoliating effect, otherwise it will only have a bactericidal effect. Salicylic acid may have superior properties in clearing black acne. Its body cuticles are rich in lipids. The fat-soluble properties of salicylic acid penetrate deep into the stratum corneum and pores by fusing with lipids, but are less likely to cause irritation to dermal tissue than the acid itself. The acid concentration and surface area need to be used very accurately if you want to treat pore acne problems and burn the skin.
