In general, mesotherapy was a 1952 French doctor. It is a treatment method developed by Pistor and is now widely practiced worldwide.

The treatment method involves injecting a small amount of the therapeutic agent into the skin layer and the subcutaneous layer using a special injection device and a microinjection needle.

Mesotherapy is the treatment of most severe acute and chronic pain, partial obesity, and cosmetic surgery to increase blood circulation and lymphatic circulation at the site of pain, partial obesity, skin wrinkles and skin aging, It increases the elasticity of the skin. Its effect is immediate, there is no pain in the treatment, and there are few side effects.

In this mesotherapy procedure, it is necessary to finely adjust the thickness of the needle according to the thickness, depth, angle, amount of injection and the operation site.

In general, when a practitioner manually receives a predetermined medicament in a disposable syringe and manually injects the medicament part manually, it takes a lot of time due to a long time of procedure, and there is a problem that the operation is very inconvenient due to excessive fatigue. A meso gun or an injection gun is used as a means for automatically injecting a chemical liquid.
