Confidence and Comfort. Helping to redesign mesotherapy.

A redesign of a medical tool is no easy feat. When this customer returned to CES to improve their mesotherapy injector tool we recommended a design centered around improving the customer experience. Our designers and engineers broke the work flow down to its essential systems and rebuilt it piece by piece using more intuitive processes. The resulting design delivers a sleek, fully automated system that comfortably provides hours of use.


Mesotherapy is a non-surgical body sculpting treatment that has been practiced in Europe for over 60 years. However, in the United States, mesotherapy was introduced in the mid-1990’s, gaining popularity in the 2000’s. This cosmetic procedure is administered using multiple injections of dermal filler, a mixture of medications and vitamins, across the targeted area. This process is time intensive for physicians who often perform multiple procedures in one day. Our customer, a health care and pharmaceutical company, sought to improve mesotherapy delivery by redesigning the injection tool with a focus on ease of use. The device was aimed to decrease treatment times and to build operator confidence, all while simultaneously increasing comfort for the patient. The redesign would require extensive design and engineering work to bring this idea to reality.


Our design and engineering teams were challenged to develop a new, innovative method of mesotherapy delivery. The new design would have to set our customer apart from those currently on the market. Our designers began by studying a typical mesotherapy work flow and simulating procedures to get a sense of the pain points associated with treatment delivery for both physicians and patients. In conjunction with the use case simulations, an assessment of the mesotherapy market was used to identify three areas of improvement.

The first was the control and balance of the tool. Poorly distributed weight in traditional mesotherapy tools causes physicians to lose dexterity and sensitivity, making the procedure challenging. Using information gathered from role playing exercises, the design team saw that by avoiding the pistol grip design they were able to better configure the working components. Through configuration studies done with the mechanical engineers, the designers developed a pen grip design that relocated the weight over the back of the hand. The more intuitive design reduced fatigue and improved both physician control and patient confidence in the procedure. An added benefit to this design was the improved visibility of the treatment site.

Another substantial improvement came in the form of increased ease of use. This was a new approach to mesotherapy. It provided physicians a level of control which had not been seen before. In turn, there needed to be a greater focus on the interface and communication to the operator. Our designers worked with the electrical engineering team to develop an interface concept which used a full color display, capacitive touch in the component housings, haptic feedback and LED syringe level indicators. This design gave operators an ambidextrous device with 360 degree status indicators.

Finally, the device needed to be automated. This third opportunity required the design team to work closely with the mechanical engineering team once again to discuss components. Even more important than components would be the capability of physicians to control the quantity of medicine and the speed delivery of the dermal gel. A drive motor assembly was developed to deliver the gel at a specified speed, depth, and volume, all controlled by the physician. Automating this labor intensive procedure would exponentially speed treatment while ensuring consistent and controlled delivery of the dermal gel.


CES’ improvements to the injector tool provide physicians with a cutting edge mesotherapy system. The increased speed of delivery allows doctors to treat more patients with confidence and comfort throughout the day. The customer has since returned to CES to work on many other health care initiatives.


The client is a global health care and pharmaceutical company focused on developing medical devices that use technology to deliver better patient outcomes. The company strives to create devices in those areas where there are substantial unmet needs.
