Sleeping with makeup on is not a good idea. Sleeping in your makeup is unlikely to cause long-lasting damage to your skin. During the day, your skin is in protection mode — keeping your complexion free from harmful rays and free radicals. At night, your skin goes into repair mode — creating healthy cells, regenerating levels of collagen, and more. By sleeping in your makeup, your skin must work harder to get through all that dirt and grime.
Eye Irritation & Infection
Neglecting to remove eye makeup can cause dryness, redness, irritation and infection.
Dirt and makeup trapped against your skin cause environmentally induced oxidative damage. This leads to a breakdown of the skin barrier and prematurely ages your face. It can also increase your exposure to free radicals leading to collagen breakdown and skin that ages faster.
Leftover makeup residue can inhibit the absorption of skin-care products by creating a barrier that prevents beneficial ingredients from penetrating the skin’s surface that means your beloved moisturizer won’t be able to nourish your parched skin.
If you don’t cleanse your face, dirt and dead skin cells they stay on the skin, clogging pores and leading to chronic inflammation in the form of pimples.
Develop a rash.
Makeup often contains irritants like dyes and perfumes that, when left on the skin for long periods of time, can cause inflammation.
So, even if you are super tired, wash your face before heading to bed your skin will thank you later. Cleanse twice daily. At night, if you wear heavy makeup, start with a quick makeup wipe. If you have normal to dry skin, find a gentle cleanser to lift off impurities, makeup, and dirt. For oilier skin, look for exfoliating cleansers with alpha-hydroxy acids, and for acne-prone skin, consider a topical treatment that contains active ingredient dapsone.
