A new study published
in the journal Dermatologic Surgery this month revealed that hyaluronic acid
(HA) fillers provide sustained dermal remodeling and stimulate collagen
production.
The researchers found
HA filler injections provide sustained clinical results and a measured increase
in collagen in the small group of 40-year-old women studied.
Each received HA filler
injections in the nasolabial folds and preauricular regions of the face.
Skin biopsies of the
preauricular regions were performed prior to treatment and at three and nine
months after the procedure.
The 16 patients who
completed the study had demonstrated improvement 12 months after treatment.
Morphologic evaluation
showed increases in the epidermal layers and a statistically significant
increase in collagen fibers at three and nine months after the initial
procedure.
Researchers, including
Fabiana Braga, M.D., noted the results are explained by the presence of HA gel
on the dermis and by the dermal remodeling induced by the HA filler injected
under the surface.
This is good news for fillers that incorporate
hyaluronic acid, including Captique, Esthélis, Elevess, Hylaform, Juvéderm,
Perlane, Prevelle, Puragen, Restylane, and more.
The study is a significant breakthrough as it shows
the benefits of HA fillers are not limited to the short-term wrinkle reduction.
