Soft Tissue Fillers
Soft tissue fillers – which fill out the skin or the tissue under the skin – are used to smooth out wrinkles, which begin to appear as collagen and elastin fibers in the skin break down. This breakdown can be attributed to aging, excessive squinting, frowning, smiling, and especially smoking. Fillers are also used to restore volume that may be lost through aging and weight loss.
Types of fillers
Permanent- various materials are available to produce long lasting results however these products are more difficult to use, and carry some increased risks when compared to temporary fillers
Temporary- The most common type of dermal filler. These are either collagen based or hyaluronic acid based and come in various formulations.
Fat grafting or lipofilling – transfer of fat from one part of your body to another
Fat grafting – procedure
Fat transfer is widely used because it is tolerated well and you cannot be allergic to substances taken from your own body. In addition to filling out wrinkles, lipofilling can be used to recontour the face and provide fullness to cheeks, chin, lips and lower eyes. The fat used for fat transfer is liposuctioned from another part of your body like the abdomen or thighs and injected into an area of the face that requires more volume.
Injected fat lasts longer in larger areas of non-movement, so while it is successful for the correction of grooves under the eyes and sunken cheeks, it is not as successful for creating fuller lips.
Fat grafting can also improve atrophic aging of the hands. Fat grafting is usually performed on an outpatient basis. Both the area from which the fat is taken and the treatment site are anesthetized with a local anesthetic. Using a small needle attached to a syringe, fat is removed from a donor site where you have spare fat, such as your abdomen. Once removed, your fat is processed to remove excess fluids and then reinjected using another needle, which is placed just under your skin beneath the wrinkle, or deeper if contour change is desired. The procedure may need to be repeated until the desired correction has been achieved.
Swelling and bruising is expected after fat injection. Discomfort following the procedure can be easily controlled with medication. Although your body may resorb some of the fat a significant portion will survive and produce long lasting results
