Acne is not one problem. Active spots and congestion are not the same as red or brown marks, or as texture left once the breakouts have settled. Each one is approached differently. The consultation looks at which of these the skin has now. A chemical peel or IPL is chosen to match it, together with home care you can keep up. You are told what to expect before anything is booked. If a doctor is already treating your skin, say so then.
