My new go to for relieving stress in the body and promoting collagen is using the traditional Chinese cupping technique using silicone cups at home. You can go here to amazon to purchase the cups. Silicone Cups for Purchase

Cupping benefits are the following:

Release scar tissue and fascial adhesions.
Reduce painful trigger points.
Improve circulation, blood and lymph circulation.
Relieve pain.
Promote mobility and range of motion.
Improves mature scars.
Decrease toxins.
