With age, the face gradually loses fat tissues, which causes collapse in the cheeks, loss of fullness of the cheekbones and a hollow appearance around the nose and eyes. To restore the volume lost, different types of dermal fillers can be used. These fillers can be synthetic, or naturally obtained from the individual's own fat tissue.
The procedure involves local anaesthesia in the area where the fat will be taken. These areas are generally fat-rich areas, such as abdomen, waist, or hipline of the patient. Then fat is suctioned through liposuction with the help of the cannula, and processed to be ready for injection. Next, the fat is injected again into the relevant part in the individual’s face through special injectors. To the patient’s advantage, using his/her own fat cells avoids injection of foreign substances to the body. The patient can also benefit from the stem cells in the fat tissue, which provides vitality, brightness and freshness to the skin.
By the end of six months to a year, some of the fat injected may dissolve. Hence sometimes the procedure needs repeating for once or twice to achieve a permanent result depending on the individual’s situation. Remaining fat can be frozen, if there is any, for later use in other sessions. However, freshly taken fat is always more resistant than frozen fat.
Swelling in the fat injected areas is normal especially in the first three days following the operation. In this period, the patient should avoid direct exposure to sun and use sunscreen. Swelling rapidly disappears after three days.
