Cryotherapy uses liquid nitrogen to freeze and destroy hypertrophic (raised) scars by either applying liquid nitrogen on the outside of the scar or by injecting liquid nitrogen directly into the scar.
Next, corticosteroids are injected into the scar to reduce the size and thickness of the scar further.
This procedure is normally repeated multiple times (3 or more) in 4-week intervals. You should see gradual results with each session. After your last session, your scar(s) should continue to improve. However, in some cases, scars may grow back after treatment.
