What Really Happens When You Shave Your Face

As with any skincare treatment, you need to make sure you take care of your skin afterwards to get the most out of it and to avoid irritation. "You need to use moisturizer when you are done," says Dr. Sal. In addition to moisturizing, Dr. Sal suggests it's absolutely essential to protect your face with sunscreen, which we all know you should be doing anyway. "Part of the reason why you have hair is that it is a body protector," he says, "[So you need to use] sunscreen after you shave."

Sosnick also agrees that moisturizing is one of the most important steps post shaving. He suggests choosing products with specific ingredients including aloe vera, chamomile, allantoin and AquaCactee, which comes from the cactus plant. "It's always important to find [a product] that is both dermatologist and allergy tested." If you plan on applying makeup post shave, Dr. Goldenberg says you should wait approximately an hour.
