Acne scar revision is a specialised field. Before I go on about other treatments, I do believe that INFINI is a leap forward in the field of scar revision. As a heads up, I perform all forms of acne scar revision Fraxel, Profractional, Fraxel 1550, CO2 RePair, CORE CO2, fully ablative erbium, Dermapen, skin rolling - derma roller, fillers, surgical subcision etc....etc....etc... I find INFINI the most challenging procedure to perform. Why? Because, as the name suggest, treatment parameters are infinitely variable- depth 0.25- 3.5 mm. Technique - pinch to decease depth, stretch to increase depth. Treatment levels 1-20. Pulse duration 10- 1000 ms. These are all tailored according to your scar types, downtime, and MOST importantly your scar location. e.g.-- 3.5 mm Level 20, 600ms on your temple near the artery and nerve, stretch technique can be an absolute disaster. If this were to happen, it gives the INFINI treatment a bad rap. You will require a Specialist to give you the best results. I perform all INFINI treatments myself, and will not delegate it to an aesthetician. I think realistically it would take 6-12 months to train a nurse to perform this procedure, with the guidelines and SOP ( standard op. protocols) done by a dermatologist or plastics BEFORE the procedure. For the best results, one should target the acne scar type with ideal treatments. 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, 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 surgery. The majority of patients will have a collection of different scar types, and hence a tailored treatment 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.
