1. Prepare the nails and apply your favourite nail varnish as usual. Leave the nail polish to dry completely - this will take between 20 minutes and 30 minutes, the longer, the better. If your nail polish was applied much earlier (the night before, for instance) then you must clean the polish surface free of oil, grease or moisturiser by wiping the nails with the Cleansing Wipe and allowing to dry. 2. Once the nail polish is completely dry, apply a coat of Gel Illusion to the nail and place under the LED lamp for 60 seconds. Apply another coat of Gel Illusion if desired and cure again for 60 seconds. NB. Do not allow Gel Illusion to overlap from the nail onto the skin or this will result in a poor bond. 3. Remove the sticky layer with the Cleansing Wipe to reveal beautiful, shiny, gel-like nails.Removal: Gel illusion can usually be peeled off but if not, it can be easily removed with a quick soak in acetone-based remover.
