Ways Of Treating A Hypertrophic Scar

Cryotherapy

Cryotherapy involves the use of liquid nitrogen to freeze a hypertrophic scar. It is often very successful at smoothing out all types of scars and reducing their appearance. It is most commonly used for small scars. One technique known as intralesional cryotherapy involves inserting a needle into the hypertrophic scar and injecting liquid nitrogen. This way, the nitrogen gets into the center of the scar, under the tissue, and freezes it from the inside out. This treatment is considered very safe, though it does have a few side effects. For instance, some patients experience pain at the treatment site during and after the treatment. Some patients also have a loss of pigmentation at the treatment site. Despite these side effects, which are often temporary, many individuals find cryotherapy to be effective enough to be worth it.
