According to Home Remedy, eyeliner should be removed properly before washing the face. The article recommends using a cotton swab, and to dab it into the eye make up remover. Gently wipe off the eyeliner using the wet cotton swab. Petroleum jelly may also be used in the absence of eye make up remover.
According to Everyday Health, not removing eye makeup, including eyeliner, can lead to eye dryness and irritation. For people who use contact lenses, this can leave deposits on the lenses. This can impair
vision and may feel uncomfortable for the user.
Everyday Health recommends gently washing off eye make up every night before going to bed to make sure that it does not get into the eyes and cause product build-up and eye damage. A Huffington Post article points out that while leaving eyeliner on during sleep cannot cause fine lines or acne, it can cause significant eye irritation and clog hair follicles. The clogged areas are prone to inflammation that may require medical treatment.
Aside from eye make up remover and petroleum jelly, Brasserie Alize says olive oil, coconut milk and baby oil may also be used to remove eyeliner. Simply pour a little of any of these on a cotton ball and rub it on the eyes. If clothes become stained with eyeliner, Good Housekeeping recommends pre-treating them with a pre-wash stain remover before washing.
