How long will it take before i notice a benefit from using mederma?

Scar treatment: Scar creams are anecdotally successful & may work early on-silicone based creams or sheets probably work best. If you don't see improvement by 2 months it likely won't change the scar, although scars continue to improve & soften for up to a year. Most treatment to improve the appearance of scars like this use special technology to remodel the skin such as fractional laser treatments.
