In fact for your first few sessions I would subcise your scars, micro needle manually your forehead, then consider either RF or CO2 fractional laser. 4-8 sessions depending on the degree of sub dermal fibrosis you have. See Dr Emil Henningsen or Prof Tony Chu if you are in Europe. Acne scar revision is a sub-specialised field. For the best results, one should target the acne scar type with ideal treatments methods and not just one device. It is the dermatologist or plastic surgeon and the settings behind a device combined with proper technique that will give you the best results. For example deep ice pick scars, and narrow box car scars can be treated with TCA CROSS peels, mixed scars, rolling, and atrophic scars treated with fractional devices such as Fraxel, fractional lasers, PRP and INFINI radiofrequency. Atrophic scars (depressions) can be treated with either fat grafts, or with HA dermal fillers. Tethered and anchored scars are best treated with surgical techniques such as subcision. Other surgical techniques that we use include punch elevation, surgical elevation, punch excision and traditional excision of focal scars. The majority of patients will have a collection of different scar types, and hence a tailored treatment METHOD will be best. Careful examination, especially under angled lighting with scar mapping will give you an understanding of what are the best options for your scars. In the majority of patients its finding the correct combination that give you best results, and everyone is unique! All the best, Dr Davin Lim. Acne scar dermatologist specialist. Brisbane, Australia.
