Be ready to fill out a medical questionnaire and describe what medications and skin care products you are using. Your therapist will do an analysis of your skin, look for any interactions between products and medications, and devise a treatment plan that’s suitable for your skin type and condition. If possible, come to your appointment without anything on your skin; otherwise your skin care professional will cleanse your skin. Start your care when you are ready to commit to a series of treatments and a home care regimen.
