There is no way to remove scars (other than replacing them with other scars).
There are several treatments with scientific evidence that make small improvements in normal healing scars.
1. Scar massage
2. Silicone sheeting
3. Topicals like Mederma
Timing of the use of these treatments is important and using something like Mederma too early can cause wound healing problems.
Remember, it won't remove the scar but it will make them less noticeable.
For atypical scars (keloids and hyertrophic scars there are additional treatments like steroid injections which carry separate risks but may be of some benefit).
I hope this helps.
