Avoid sun exposure, self-tanners, and tanning beds for at least one week leading up to your appointment. Discontinue retinoids, exfoliants, and harsh skincare products three to five days before treatment. If the area requires shaving, do so the day before, but avoid waxing or using depilatory creams. Arrive with clean skin, free of makeup, lotion, or deodorant on the area to be treated.
