Dr Coleman just received the first shipment of Evolence to his office in TriBeCa. Even though the FDA approved this innovative form of collagen as a dermal filler in June 2008, Evolence just now being delivered to offices.
The Aesthetics Group of OrthoNeutrogena, a division of Johnson & Johnson, will only sell Evolence to a physician who has been trained in its use. Dr. Coleman flew to Grand Cayman earlier this year to inject Evolence into patients, and he now will train other physicians in the use of Evolence.
The pricing for Evolence is similar to Radiesse, Restylane and Juvaderm; however, more Evolence may be necessary to obtain the initial correction. This increased expense is offset however, by the longer duration of the correction with Evolence. The FDA trials in the US were only for six months, so the press release for the FDA only mentions six months duration of the correction. However, the European Evolence website says that the results last up to twelve months; and the experience of injectors in Europe is that it lasts even longer.
Above are photographs of one of Dr. Coleman’s patients he treated with Evolence in the nasolabial folds, lips and around the chin. This patient experienced minimal bruising and surprisingly little swelling as seen at twelve hours (middle photograph). The right photo is one month after the procedure and demonstrates notable softening of the deep wrinkles and folds.
More photos soon from Dr. Coleman. In the meantime, please look at the Evolence before and after gallery for more examples.

Rhonda Rundle of the Wall Street Journal today wrote an article entitled “Stem Cells and Breast Surgery” in which they discuss the process of “super-charging” fat grafts with stem cells and other factors by a special processing method. This process has been developed for commercial use by Cytori Therapeutics. Ms. Rundle does a nice job of explaining the process and the controversy.
She used the diagram below from Peter Rubin of the University of Pittsburgh, recent recipient of the Presidential Early Career Award for Scientists and Engineers (PECASE). I think that the diagram is helpful in understanding this process. Click on the image to open up the diagram in another window.
More discussion of this the impact of stem cells on fat grafting and breast surgery will appear in future posts.

There is a new filler on the market! An innovative form of collagen for injection, Evolence was approved by the FDA in June 2008 and will be available in the US soon.
Collagen Corporation introduced the original collagen for injection into the skin, Zyderm and Zyplast, over 25 years ago. They were made from cows (bovine), lasted two to five months after injection and required skin testing to determine potential reactions to the product. Evolence is made from pigs (porcine), can last over a year and requires no skin testing. Porcine collagen is more similar to human collagen, and has been used safely in the production of heart valves for years.
Hyaluronic acid based products like Restylane and Juvaderm produce their effect by attracting water to the surrounding tissues. The advantage of a collagen-based product such as Evolence is that it mimics human collagen by providing a matrix like support structure for the skin.
Colbar of Israel asked me to be on their medical advisory board over three years ago. I met with the executive from the company who I knew from Q-med and the Restylane products. She said that the company wanted me to be involved in the evaluation and development of Evolence. She explained the GlymatricTM technology used to link the collagen dramatically increased its stability and longevity.
Even though I did not join their board, as I attended many plastic surgery meetings in Europe and Asia over the next years, I heard many positive comments from the physicians using Evolence: They claimed less bruising and swelling and noted a different effect than filling with hyaluronic acid fillers. Finally and perhaps most importantly, the European and Asian physicians claimed that Evolence lasted much longer than other non-permanent fillers, up to two years.
I was not surprised when over a year ago I heard that Johnson & Johnson acquired Evolence for international distribution by the Aesthetics Group of OrthoNeutrogena. Another executive from Q-med who now works for Johnson & Johnson invited me early this year to fly to Cayman to inject Evolence in patients, so I could understand better the advantages of the product.
In the Cayman Island, I was able to perform injections into many areas of the face, using both Evolence and Evolence Breeze (the formulation for lips). The products exceeded my expectations, and I was pleased to hear that Evolence was approved by the FDA in June 2008 and will be available in the US soon. Evolence Breeze will probably be available in the near future.
The patients that I have already treated with Evolence have apparently had great results. I think it is a welcome addition to the tools in my practice for rejuvenating the face.
Before and after photos for Evolence coming soon.

The degree of sculpting possible with structural fat grafting to the breast is particularly advantageous in the challenging correction of tuberous breast deformity. The tuberous breast is a deformity in which the lower skin of the breast (the lower pole) is abnormally constricted (tight) and short. In addition, the normal fold of the breast (the inframammary fold) is higher that it would be under the normal breast. These two combined make the breast shape distinctly abnormal, and prevents the fluid roundness of a normal breast. In the more problematic cases, the tightness of the lower breast makes the nipple and areola appear much larger and more puffy than in a normal breast. treatment for this problem using structural fat was first described in the journal of Plastic and Reconstructive Surgery last year by Coleman.
In the case below, the skin envelope of the breast was selectively expanded with fat placed immediately beneath the skin. No fat was placed under the central breast (the nipple-areola complex). This changed the relative proportions of the breast creating a natural appearing and shapely “A cup” after one procedure (see below). The patient desired larger breasts after the first correction, so further augmentation with fat grafting was performed (see below) to bring her up to a “B-cup.”
The time requirement of such a fat grafting procedure should not be underestimated. The time to harvest, refine, and place fat into the breasts in this fashion will take many hours. In the patient shown placement of fatty tissue into the breasts took about seven hours for the first procedure and five hours for the second. The reward of the time and effort is a dramatic change, which is much more natural than if implants had been used. Fat grafting for correction of tuberous deformity leaves the patient with natural appearing, normal breasts. As with any breast procedure, patients must be aware of the potential risks and complications of fat grafting to the breast.

Photo on the right was taken at almost 5 years after the second fat grafting procedure in which 300cc was placed into the left breast and 340cc into the right.
Long-term studies still need to be completed. Dr. Coleman is currently working with other plastic surgeons, oncologists and radiologists at NYU to develop a multi-center prospective study examining the use of fat grafting in the breast.

Zeltiq Aesthetics has developed a breakthrough biotechnology for reducing unwanted fat. The Zeltiq device uses cryolipolysis to precisely cool fat and induce lipolysis (the breakdown of fat) apparently without any permanent damage to other tissues (skin, nerves, muscle and bone) around the fat. The technology allows for natural body sculpting.
Harvard Medical School and Massachusetts General Hospital performed the pioneering research that evolved into a non-invasive system to reduce subcutaneous fat. They first presented their research at the 2008 meeting of the American Society of Laser Medicine and Surgery. Please refer to the scientific paper on cryolipolysis from this meeting for a detailed explanation.
Dr Sydney Coleman is on the physician advisory board for Zeltiq.
More information about this and other non-invasive or minimally invasive methods of fat removal will follow.
