Effects are usually seen after the first treatment, with ongoing improvements seen week after week during a course. Your SkinBase therapist will perform an initial consultation and recommend a course length to you. Usually, this will consist of 6 to 8 treatments, 7 to 10 days apart. Skin problems such as acne or acne scarring, or deeper forehead wrinkles may require up to 20 weeks to achieve full improvements. After a course is completed, a single monthly treatment will maintain your skin’s improvements.
