Immediately following a lash lift, for a minimum of 24 hours, avoid heat, steam (including cooking over steaming stovetop, grilling and opening oven doors), saunas, water, oils, lotions, creams, shampoos, face washes, makeup remover wipes or pads on lashes. Only approved product to put on immediately after a lift may be applied by your esthetician. Because your lashes are still malleable (shape-shifting), a side sleeper or face sleeper may notice that one or both eyes may raise or drop, leaving the lashes misshaped. Sleeping on your back is best. Avoid direct sunlight right after your treatment, as this can weaken the lift lotion and fade the tint.
