Before you reach for some makeup to cover a popped pimple, there are a few things you can do to ensure it won’t do more harm than good. Ahead are ways to cover up your blemishes correctly, according to dermatologists and beauty experts. (1) Start with covering the area with a spot treatment, followed by a moisturizer to create a barrier between your skin and makeup. (2) Do not apply concealer with your fingers. Use a brush or an applicator instead, and be gentle using a dabbing motion. (3) After applying makeup, keep your hands off your face.
