What kind of subcision tool is this?

I have been performing subcisions for elevating and smoothing all kinds of scars--chickenpox, acne, post-surgical and post-trauma--since 1995 when it was first introduced. Conventional and traditional subcision was performed with an ordinary sterile needle, the kind typically intended to be attached to a syringe for injection purposes. These come in various diameters and lengths to correspond the variety of anatomic sites and purposes for which they are intended, which makes them excellent tools for subcising the varying sizes, shapes and thicknesses of scars. Unfortunately, these days, so many venues are in to hawking the expensive "next big thing" fraxel laser or RF device, rather than offering tried and true, quick and relatively inexpensive and safe and proven effective techniques, like subcision. So, it is very important to make sure to consult a board certified cosmetic dermatologist experienced in subcision. Hope this helps.
