Having eyelash extensions certainly has its perks. They make it possible to flaunt thick, long and fluffy lashes at all times — no mascara necessary — so you can pull off a literal no-makeup makeup look. But, despite how well lash extensions transform your natural lashes, you may want to pump up the drama even more. So, what are the rules of applying makeup with eyelash extensions without damaging them? Ahead, we put together a list of dos and don'ts with the help of Cristina Monaco, who specializes in cosmetic dermatology at the Schweiger Dermatology Group in New York City. Stay Away From Oil Oil can cause the glue in your extensions to break down, so you should always look for oil-free makeup products. In addition to using oil-free makeup, you should make sure that your makeup remover and daily skincare routine is oil-free, as well. “Using a makeup remover that is oil-based will cause those lashes to slide right off,” warns Monaco. Consider Garnier SkinActive Micellar Cleansing Jelly Water with Charcoal, which is formulated without oil or fragrance. This gentle cleanser is especially suitable for acne-prone skin.
