Does massaging help flatten raised or hypertrophic scar tissue?

Hypertrophic scar: Actually, the ability to scar is in your dna. Sometimes where the scar is on the body predisposes a cut to scar thick. Rubbing the area may make it worse as it tries to heal. The best answer is to try to keep the area that has been cut relaxed and immobile. That is hard to do on the torso, which scars the worst. Visit your dermatologist and he or she may be able to help with an injection.

Yes, it can: I will often have my patients massage raised scars to help hasten their maturation. It may not help, but it certainly doesn't hurt.
