The Consequences of Sleeping with Your Makeup On (And the 5-Minute Nighttime Routine That Saves Your Skin)

The Science: Free radicals from pollution and UV exposure (that your makeup has trapped against your skin all day) continue to break down collagen and elastin fibers overnight. This process, called oxidative stress, is magnified when not cleansed away.

• The Consequence: Earlier and deeper appearance of fine lines, wrinkles, and a loss of skin elasticity and firmness. You are literally fast-tracking the aging process.

3. Dull, Uneven Skin Tone & Rough Texture

The Science: Overnight, your skin is in repair mode, working to shed dead cells. A layer of makeup blocks this natural exfoliation process, causing a buildup of dead skin on the surface.

• The Consequence: A rough, flaky texture and a complexion that looks lifeless, tired, and lacks its natural radiance. No amount of highlighter can fix this kind of dullness.

4. Eye Area Irritation & Potential Damage

The Science: Mascara and eyeliner flakes can migrate into your eyes, causing micro-scratches on the cornea or bacterial infections like styes. The delicate eye skin is also prone to milia (tiny white cysts) from clogged glands and exacerbated dryness, leading to more prominent crow’s feet.
