The first step to a morning and evening routine is washing your face. "Cleansing is key for healthy skin and is a crucial step," Somerville explains. "If you have dry or sensitive skin, just splash warm water on your face or use a gentle gel cleanser that does not contain sulfates. If you're oily or acne-prone, cleansing with a salicylic acid-based cleanser is a good option." If you wear a lot of makeup, wash your skin twice or use a cleansing brush.
