To remove glue after a lash lift, use a oil-based method with baby oil or coconut oil on a cotton swab, a dedicated eyelash glue remover, or a water-soluble remover on a cotton pad, applying it gently to dissolve and lift the glue. For the oil method, apply a generous amount of oil, let it sit for a few minutes to soften the glue, and then gently wipe it away with a Q-tip or cotton pad, using a spoolie to break up remaining residue
