Use an extension-friendly lash cleanser with a lash brush or disposable lip gloss applicator. DO NOT USE Q-tips as some of the fibers will get caught in your lashes.
Don’t use WAX-based eyeliners. Most eyeliner pencils contain wax. The wax helps the eyeliner stick to your eyelids-and also your lashes. Removing the wax-based eyeliner can turn into a battle of whether they will be taking lashes with them. If you are still set on using an eyeliner, some extension-friendly choices tend to be liquid or gel-based eyeliners.
Powder eyeshadow is the best to use because it doesn’t contain oil like some of the cream and paste shadows do.
Eyelash Extension Care 101
Certain beauty products can break down lash adhesive more quickly than others. The reason why you ask? Cyanoacrylate.
Cyanoacrylate is the main ingredient in eyelash adhesive and it happens to be a polar molecule. All molecules can be polar or nonpolar but generally, polar molecules are dissolved and/or broke down by other polar molecules. Many cosmetics contain both polar and nonpolar molecules. Since cyanoacrylate is polar, products that contain more polar molecules should be avoided.
Foundations and powders don’t have direct contact with the lashes, so they are generally safe to use no matter what the chemical composition.
The focus here is on makeup remover, eyeliner and eyeshadow.
Makeup vs. Lash Adhesive
Many oil-based products, including makeup removers and cleanser contain molecules that have a polar head (or a polar part to the molecule). This polar part will “attack” the cyanoacrylate and weaken the bonds between the lash extension and the natural lash. Even makeup removers that are labeled “oil free” often contain polar molecules. For this same reason, cleansing wipes are not the best option. Eye makeup should be removed using an extension-friendly lash cleanser.
Cleanse gently with your hands. If you are wearing an eyeliner or makeup that requires a little more attention to remove, it is
best to use a lash brush or disposable lip gloss applicator. You don’t want to use Q-tips because the fibers will get caught on your lashes.
