Filler or fat transfer? (Photo)

While the allure of a permanent result is certainly understandable, the problem with fat grafts (and with permanent fillers, for that matter) is that they are permanent and that adverse reactions to them, such as the formation of lumps and nodules can be very difficult to treat. In the case of fat grafts, since the fat grafts retain the characteristics of the region from which they were taken (i.e. belly, thighs, hips), with the passage of time, just as one can develop a midriff bulge, so can the fat injected into the cheeks. Fat injections are also an expensive, miniimally invasive procedure with downtime. One step requires large cannulas to withdraw fat from the thighs, buttocks or hips and a second procedure to inject it under the eyes.
On the other hand, the use of a robust, off-the-shelf HA volumizing filler appropriately placed in the upper cheeks can create a smoother, more desirable, gradual transition between the upper cheeks and the under-eyes in about fifteen minutes, with immediate results and little to no significant downtime.. Make sure to see an experienced, board certified cosmetic dermatologist. Best of luck.

Both have nice cosmetic outcomes it depends really what you prefer. Fat Grafting depends on your metabolism and current diet, results can be short lasting or long lasting. Dermal filler we know more or less that it will last x amount of time and they do have many peer review studies especially on the allergan products to show that they work on several hundreds of patients.
