One of the more common approaches now is to use a technique called subcision. This involves the cutting of the fibrous scar tissue under the skin to release the depression on the skin surface, followed by the injection of dermal filler or nano-fat to fill the space created by the cutting of the scar tissue. The final results can be very good but the methods for cutting the scar tissue can be uncomfortable and leave bruising

In response to the challenge Sterimedix, a UK medical device company, and a plastic surgeon in London, Dr Olivier Amar, have between them created a product that can perform subcision without the unpleasant after-effects of traditional methods.
