Salicylic Acid is an amazing component for oily skin. It’s a famous BHA that chemically exfoliates dead cells, kills bacteria, and prevents acne. It works as a strong pores cleanser. AHAs are not effective for removing sebum from pores, while BHAs are leaders in this space. Salicylic Acid also helps to shrink pores, remove acne scars and make skin tone even. Pay attention: concentration matters! This ingredient is rather aggressive. It can lead to irritation in high concentrations. If your skin has never seen this component before test the product first.
