The application of anesthesia is a major component of Hair transplant procedure. 

In classical Hair transplant procedure local anesthesia is provided via numerous punctures leading to pain and discomfort for the patients.

An injection without needles, is that even now perhaps one or the other readers will ask now. The answer: Yes, that works! With the Needle-Free system, which injects the local anesthesia directly under the scalp without any needles.

And it is great for patients who are afraid of getting an injection.

The injection of the anesthetic happens so to speak in “high speed”. There is a spring in the piston of the Comfort In System. At the lower end there is a nozzle with a piston in which the anesthetic is filled. The lower opening of the piston is about 0.15 mm in size and can be filled with 0.5 ml of an anesthetic (which is quite sufficient in a hair transplant). When the trigger on the top of the stylus is pushed, the piston in the nozzle will shoot down.

As a result, such a high pressure builds up in a short time that the anesthetic is injected directly through the skin into the underlying tissue. The piston has only about a third of a second of contact with the skin. This makes the application virtually painless. Only the moment in which the anesthetic gets under the skin, can be perceived as something unpleasant.

In addition, the surrounding tissue is not injured because no needle is used. The risk of infection via the puncture wound is thus virtually eliminated. Thanks to a special system that is integrated directly into the Comfort In Pen, the dosage can be individually adapted to the patient.

Needle-free injection offers some advantages over the subcutaneous (in the skin). Anesthesia administered in this way usually works faster and can be started earlier.

The injection procedure with the Comfort-In System is certified and patented and easy to use anywhere on the head.
