Got burnt during first sitting in Feb 17. Got redness which subsided in a week, overtime brown marks developed on both cheeks. Doctor reassured me they will fade and I can continue laser. Prescribed ointments like melalite15, melaglow rich, lumicep but none helped fade the scars. Gave me one laser sitting for the brown marks which seemed to help to a very limited (5%) degree. It's a year and a half later and I still have brown marks. Is there any treatment? Any essential oils I could use?
