Even if you&amp;#39;re lucky enough to have relatively problem-free skin, you still need to exfoliate. You can use either a scrub or an enzyme-based exfoliator. If you prefer a scrub, look for one with jojoba beads—they are gentler on the skin than harsh scrubs and better for the environment than scrubs with plastic micro-beads. We like Neutrogena Naturals Purifying Pore Scrub, $7, drugstore.com. For enzyme-based exfoliants, look for a product with bromelain, an enzyme derived from pineapple. You&amp;#39;ll find it in Colbert MD Daily Nutrition for Skin Intensify Facial Discs, $64, colbertmd.com.
