Product Description 🖤 What does Paula's Choice 2% salicylic acid do? 1. ✨ Exfoliation ✨: Salicylic acid has excellent exfoliating properties. Compared with physical exfoliating products like scrub creams, low-concentration salicylic acid is gentler. 2. ✨ Whitening ✨: Salicylic acid accelerates the shedding of the stratum corneum. At the same time, it removes melanin from the skin cells, revealing lighter skin, thus achieving a whitening effect. 3. ✨ Unclog pores ✨: Salicylic acid can penetrate the stratum corneum and pores, dissolving oil and dirt within the pores and clearing them out, thereby unclogging pores. 4. ✨ Oil control ✨: Salicylic acid is lipid-soluble. It cleanses the skin by blending with the skin's oils, helping to control excess oil production.
