In the news is the discovery that within the harvest of fat cells during liposuction stem cells exist. When correctly processed stem cells will survive when injected with fat. These cells release growth factors which stimulate survival of fat and other cells. Injection into the buttocks permits longterm enlargement and reshaping without silicone implants. Advances in digital mammography permits differentiation of fat injection induced calcifications from malignant ones making this the procedure of choice for women with breast asymmetries or those looking for a one cup size enlargement. Fat injections to the naso-labial folds from the nose to the corner of mouth and to the lower chin, lips, eyelid/cheek grooves and overlying the cheek bones are growing in popularity. Natural looking, long lasting results (may be permanent) make this my preferred technique. Plumping of the cheeks, outer eyelids and lower facial regions for many can rejuvenate the face as much as a facelift with less risk, scarring and downtime. Fat is harvested with a 2.5mm cannula using local anesthesia from most unwanted fatty areas. Injection with small blunt canulae make this a safe and effective procedure with results lasting years. Fat may be refrigerated for repeat sessions within three days to further enhance results. Multiple donor sites are possible: who would not want us to take a little more from around the waist! Recuperation is minimal with most patients looking better within three days. You can have fat injected after Christmas and look smooth and fresh for New Year’s Eve. Facial fat injections are successful 2/3 of the time. The remaining patients experience loss of the injected fat which can be irregular. Even so the injected fat can stimulate new collagen formation resulting in smoother more youthful appearing skin. Platelet rich plasma or PRP has been used for injection to promote healing and the so called Vampire Facelift. An interesting concept, appropriate amounts of platelets may not be able to be harvested and injected in the physician’s facility. I have not seen any significantly improved results published or in person.
Stretch marks although quite prevalent have been an elusive condition to treat. The pink discoloration caused by tissue inflammation usually resolves spontaneously with time. The Pulsed Dye Laser and Intense Pulsed Light are helpful in expediting their resolution. The crinkled depressed skin caused by disruption of collagen and elastin fibers can be improved with the use of collagen stimulators such as Radio-Frequency and Electromagnetic energy “Lasers”. We have commenced injecting the stretch marks and neck wrinkles with fat injections or Sculptra with a good preliminary response. We are conducting further investigations into this promising treatment.
