Dermal Fillers Can Provide Minor Facelifts

A new study using 3D imaging shows that dermal fillers can also provide some ‘lifting’ effects, as well as their normal ‘volumising’ effects in facial rejuvenation therapy. 

Dermal fillers are ranked second of the top five non-surgical cosmetic procedures, behind botulinum toxin injections. While dermal fillers have been increasing in popularity, plastic surgeons are trying to work out the best application for facial rejuvenation without surgery. Most studies have used subjective rating systems with little generalisability as a result.

The results of a recent study showed that in addition to ‘volumising’ effects, dermal fillers may also have variable ‘lifting’ effects. Sebastian Cotofana, MD, PhD, of the Mayo Clinic,and colleagues came up with a study to measure the true lifting effect of soft tissue fillers.

In this experimental study, the researchers performed standardised dermal filler injections in facial cadaver specimens, in the areas commonly targeted for facial rejuvenation: the forehead and temple; the midface region, including both the medial (central) and the lateral (sides) areas; and around the mouth and jawline.

Dr Cotofana and colleagues performed before-and-after 3D scans of the facial surface to measure the effects of the injections. 

Dermal filler injections showed significant increases in local soft tissue volume in central areas of the face, consistent with the well-established clinical effects of ‘injectable’ treatment in the forehead, midface, and mouth and chin areas.

Local lifting effects were also seen from central facial injections, with up to one millimetre of vertical ‘lift’ in the forehead area, but this was not seen in the other facial areas.

Injections in lateral facial areas such as the jawline also resulted in local volumising and lifting effects. These lateral facial injections also created ‘additional regional lifting effects’ in neighbouring facial areas. Temple injections resulted in a small but significant lifting effect on the lateral midface and jawline, for example.

Combined injection techniques provided even greater benefits. Added to deep filler injection, a superficial temple injection technique produced an additional 17.5% increase in the lifting effect of the temple, plus a 100% increase in the jawline lifting effect.

“These results indicate that lateral face injections co-influence adjacent lateral facial regions and can thus induce regional lifting effects,” wrote Dr Cotofana and coauthors. The results are consistent with previous knowledge of the in-depth anatomy of the face: filler injections may lead to a change in tension of the connective tissue (fascia) under the skin, resulting in “re-positioning” of the upper skin layers.

In this way, filler injections can provide a small but significant lifting effect in a minimally invasive, repeatable procedure, although they are not as effective as plastic surgery. Besides providing confirmation on previous findings on the lifting effects of facial injectables, the study also “broadens their applicability to the total lateral face…to achieve local and regional lifting effects.”
