Will one treatment of Infini give a significant improvement to my acne scars? (photos)

You will likely need 2-3 treatments. Make sure you see someone with a lot of experience treating acne scars.

Acne is very difficult to treat and realistic expectations are required before one under goes any treatment. Infini is very good in treating acne but it requires at least 3 treatments to see good results. Generally, infini is combined with PRP, subcsion and fillers to obtain even better results. Please consult with an expert to determine if you are a candidate for this procedure.

Truth- no. You sill have tethering. Plan for at least 3-4 sessions with subcsion. Remember INFINI is only a device, make sure you have a specialist initiate the treatment. Everything from needle depth, pulse duration, and energy levels play a role. I still think there is a place for some HA filler with subcision at the end of your treatment cycle. 
Acne scar revision is a sub-specialised field. For the best results, one should target the acne scar type with ideal treatments and not just one device. The web reference below will take you to a resource to help you understand acne scar revision at a specialist level. I embedded all the videos in one page to help.

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,
