While wearing DIY lash extensions, you can certainly keep your face/eye area clean and shower with them on. When cleansing around the eyes, gently navigate with a cotton swab to reach any tricky spots. If there's makeup on the lashes, carefully dab it off with a water-dampened cotton swab. It's important to steer clear of oil-based products near the eyes, as oils can weaken the adhesive bond. On the day you plan to remove your lashes, ensure to thoroughly cleanse your natural lashes for optimal lash health.
