Eye Doctor Warns Against Sleeping with Mascara On

Dr. Jennifer Tsai, an eye doctor from New York, recently shared a video on Instagram explaining why it's important to remove your mascara before going to sleep.

She said that if you leave mascara on overnight, tiny flakes can collect under your eyelids and form hard lumps.

These lumps can rub against your eye every time you blink, which can cause irritation, redness, or even scratches on the surface of your eye.

Dr. Tsai advises always removing your makeup before bed, double cleansing your lashes, and choosing mascaras that are not waterproof.

She also suggests using tubing mascara, which is easier to remove and forms tiny tubes around your lashes instead of a wet film.
