During your initial consultation, your dermatologist will go over a list of important precautions you should take before and after your procedure. Come into your appointment with a fresh, clean face and refrain from using any facial cleansers, creams, serums that contain retinoid, benzoyle peroxide, AHAs, or salicylic acid as these can have adverse effects. Post treatment, you should continuously wash your face to avoid bacterial infections, stay out of the sun or wear sun protection, and moisturize your skin frequently.
