Hyaluronic Acid

Hyaluronic acid is the most prominent glycosaminoglycan in the skin. Hyaluronic acid
potently binds to water with studies revealing on a volume basis that hyalurinic acid
draws 1000 drops of water to one drop of hyaluronic acid.  

Thus when injected into a rhytide or volume depleted areas, patients will notice that
the hyaluronic acid will volumize, soften, and hydrate the skin. In addition to these
benefits, it plays a role in cell growth, membrane receptor function, and adhesion.

Biochemically, hyaluronic acid stabilizes intercellular structures and produces the
viscoelastic network for collagen and elastin fibers to bind together.

In February 2003, the FDA approved Restylane, a cross-linked, nonanimal source
hyaluronic acid. This dermal filler was quickly embraced when found to be:
  • relatively long lasting
  • have minimal adverse effects
  • easy to use
  • ready to use out of the box,
  • did not require refrigeration
  • cost effective
  • did not require skin testing prior to treatment.

Restylane
Restylane was approved by the FDA in 2003 for the treatment of nasolabial folds.  
This dermal filler is used for correction of the nasolabial folds, marionette lines, and
glabellar frown lines, in addition to lip enhancement and cheek augmentation. Other
clinical uses include correction of the jowls and nasal deformities. In general, most
patients can expect 6 - 9 months of correction.

Perlane
This dermal filler is identical to Restylane except that it consists of larger gel particles.
This dermal filler is suitable for the correction of deeper folds, such as the nasolabial
folds, and works well for cheek enhancement. Additionally, some experienced
physicians prefer this dermal filler for lip augmentation over Restylane. Most patients
can expect 6-12 months of correction with Perlane.

Editor's Note: I have noted that many of my patients experienced satisfactory clinical
results lasting upto 24 months after the second injection given at 9 months.

Juvederm (Juvederm Ultra/Juvederm Ultra Plus)

In 2006, the FDA approved Juvederm, which is also a nonanimal stabilized hyaluronic
dermal filler.   Juvederm Ultra Plus has a higher proportion of cross-linking than
Juvederm Ultra.  Juvederm is a homologous gel with the highest degree of cross-
linking of any of the hyaluronic acid fillers and thus has a smooth consistency.

Juvederm Ultra and Juvederm Ultra Plus have indications similar  to those of
Restylane and Perlane, respectively, and do not require skin tests prior to use.

Hyaluronic Acid Precautions
The adverse effects are: discomfort with injection, erythema, swelling, and bruising.  
If injected too superficially a bluish Tyndall effect, and nodules may appear.
