Microneedling: no difference after 4 treatments. I have pitted scars and box scars.

Hi vishnumj, RF microneedling works by inducing collagen growth which can lift the skin from under so that scars, particularly acne scar appear more diminished. However, in cases where it has minimal results, you can opt for either a deep chemical peel or Fraxel, with or without hyaluronic fillers.Do remember to have active acne treated first.All the best,Justin Harper,M.D.

The best way to determine success or failure is objective. Side by side photos. Having said that, it does take 3-5 sessions spaced a month apart, with the best afters 2-3 months after the last session. A method should be used to direct treatment based upon scar types for the best results. Also the energy levels, passes and system is important in achieving the best results, and most importantly the experience of your provider. The Fiori Institute of Skin and Body, Brisbane. Australia.
