Washing off makeup at the end of the day is crucial, because it can clog pores, cause oily build-up and aggravate or trigger acne. Use a mild soap or skin cleanser to gently remove dirt, excess oil and makeup. If your skin is prone to acne, try a cleanser that’s specifically designed for acneic skin. Available brands have been expanded to include mousse formulations that make it easier to remove these impurities. Once daily use can revitalize your skin while preventing breakouts. Next, use a toner to remove any residue not eliminated by cleansing. The final step is to restore hydration with a moisturizer.
