DON'T exfoliate 24 to 48 hours prior to waxing to avoid irritation! DON'T coat your body with lotions, potions, creams, or any of the sort the day of your wax!
Unless you're a heavy sweater, have used a heavy occlusive the night before or have a very oily skin, you don't need to use a cleanser in the morning. A water rinse will do to clean your face, this will improve your skin's sensitivity and dry patches.
Avoid heavy products, like oils and sticky occlusive like Vaseline under the eye, that attract sweat and grime. These might lead to small under-the-surface white bumps called "milia". Instead, an eye cream formulated with retinol can exfoliate the area and keep it moisturized.
