According to the search results, mascara can be applied before or after false eyelashes, but it is generally recommended to apply one thin coat of mascara to your natural lashes before applying fake eyelashes. This allows the falsies to easily stick to your natural lashes and provides a more natural, seamless blend between the lashes and lash band. Applying mascara before strip lashes can even help the lashes better adhere to your natural lashes, so they’re sure to stay on even longer. However, it is important to avoid applying heavy mascara to your natural lashes, as it can cause them to deteriorate faster than they would if you did not apply glue. When it comes to applying mascara with false eyelashes, it is recommended to use a mascara formula that won’t clump and smudge the formula, but instead lets your natural lashes blend seamlessly with your falsies. Waterproof mascara should be avoided to make it easier to clean the lash strips so that they can be reused.
