It's best to avoid oil-based products around your eyes when wearing cluster lashes, as oil can weaken the bond, causing the lashes to loosen or fall off prematurely. If you must use products near your eye area, opt for oil-free formulas to maintain the longevity of your lash application. On your scheduled lash removal day, oil-based cleansers can then be used to help gently and effectively remove the lashes without harming your natural ones.
