Dermal Fillers – Advancements
in our Facial Aesthetics Portfolio
A wide variety of temporary
and permanent fillers are now available. They can
be used to restore youthful facial contours by
eliminating frown or smile lines, crows feet and
scars and they can be used to augment specific
facial features such as lips, chin, and cheeks.
Over time, these products have
become safer, easier to use and more accessible
to the patient. The number of products also allows
physicians to treat a broad scope of problems in
various ways, leading to much greater flexibility
in treatment and optimum results.
The temporary fillers include
collagen, hyaluronic acid, calcium hydroxylapatite
and poly-L-lactic acid. With all fillers, short-term
redness, swelling and tenderness at the injection
sites can occur.
- Collagen has been used
for over twenty years as a filler and is the
gold standard that all other fillers are compared
to. Collagen can be obtained from cow hide
or from manufactured human skin. A skin test
with the cow derived collagen is required prior
to the treatment to determine whether the patient
is allergic to the implant. The effect of collagen
usually lasts two to four months and can be
used to treat lines and wrinkles in the lower
half of the face as well as lip enhancement.
- Hyaluronic acid is also available from an animal
(rooster comb) or a non-animal source. Allergy
testing is not required prior to using the animal
derived product but there may be a low incidence
of allergic reactions. HA is often used for lip
enhancement but can also be used for filling
facial lines and contouring. The animal derived
HA usually lasts between three and six months
and the other slightly longer.
- Calcium hydroxylapatite not only replaces volume
to folds and wrinkles but also stimulates the
body to produce new collagen. As a result, this
product can last more than a year. Poly-L-lactic
acid is used primarily to sculpt or repair facial
defects and is not recommended for lip augmentation
or treatment of superficial lines and/or wrinkles.
Skin testing is not required for either calcium
hydroxylapatite or poly-L-lactic acid.
Semi-permanent to permanent
implants such as fat injections, and physical implants
can be effective for deeper lines, furrows and
folds as well as lip and cheek enhancement. Placement
of these can be more complex and time consuming
but relatively safe.
Filler technology is rapidly
expanding and there are many more cosmetic options
on the horizon. This is an exciting time in the
field of cosmetic rejuvenation!
