The Ordinary Salicylic Acid 2% Solution is a water-based serum specifically formulated for blemish-prone skin. This direct acid treatment contains 2% concentration of salicylic acid to help exfoliate the skin, unclog pores, and reduce the appearance of blemishes. This product is a clinical formulation with integrity, designed to address skin texture irregularities and congestion. The 30ml bottle comes with a dropper applicator for precise application. As a beta hydroxy acid (BHA) product, it may increase skin's sensitivity to sun, so sunscreen use is recommended. Patch testing is advised before full application.
