Dermatologist Dr. Joshua Zeichner tells Real Simple, "We know that the skin undergoes daily circadian rhythms, where specific activities occur in the morning and others in the evening. However, the night is the prime time to rest and repair the damage that occurs to the skin during the day as a result of environmental and other stressors."
Some expert-backed skincare tips connected to sleep that can improve your skin's health include:
Cleanse before bed: End the day by washing away any makeup, oils, pollution, and debris that can accumulate. Real Simple's experts suggest using a gentle moisturizing cleanser to properly clean and not strip the skin's natural oils.
Hydrate the skin: The beauty experts say our skin's hydration levels dip at night and recommend evening as a great time to moisturize. Dermatologist Dr. Wendy E. Roberts explains, "This is especially true if you have dry skin. Opt for a rich emollient crème packed with lipids and ceramides, as they will be highly absorbed into the clean and receptive skin." Before bed is an ideal time to use your eye cream, neck cream, and lip ointment.
Try an overnight treatment: When sleeping, use a retinol serum (3 to 4 times a week) or even an overnight mask once a week, say Real Simple's experts. (We love these beauty products that can help your skin and hair look its best!)
Keep your hair away from your skin: If your hair gets greasy, oily, or dirty, either make sure to wash it before bed or keep it away from your face. The experts note oils and styling products can easily transfer to your bedding and then cause acne. While using a hair mask or leave-in hair treatment, always wrap your hair in a towel or use a shower cap.
Sleep on your back: If possible, avoid side sleeping, say the experts. Having the side of your face planted on the pillowcase can lead to fine lines and even wrinkles, say Real Simple's skin experts. They note satin or silky bedding can create less friction on the skin and if you deal with sensitive or eczema-prone skin, use natural fiber bedding, which tends to be more soothing.
Keep your room cool and clean: The best sleep is usually in a room that is cool (from 65 to 72 degrees), as a hot room can lead to itching sensations, which can make eczema worse. Also, if you have dry skin or eczema, using a humidifier in your room can also help. (Find out our favorite items to help cool down your room while sleeping.)
Get enough sleep: Getting the proper amount of quality sleep is so vital to someone's overall health, including your skin. Real Simple's experts say 8 hours should be your minimum and if you can get 10 hours even better. (If snoring is keeping you awake, these products may help you sleep better!)
