I used mederma , bio oil and invicible. First-rate for me was invicible. It took a while but relatively less than the other ones and actually showed pretty good results. I used mederma for two months and bio oil for over 3 or 4 months...
The invicible scar is really effective in reducing the scars of all types. It is a good choice for scar removal but will require few weeks to heal, depending upon the age of your scars
