In general, deep wrinkles, folds and volume loss in
the face, lips and hands may be treated with filler
materials and fat injections. There are different volume
filling materials commercially available today. Of those,
most commonly used
is different hyaluronic acid products such as restylane,
teosyal and hyaloform. After injection under the skin
or in the lips, these filler materials last about 6-15
months. Fat, on the other hand, is obtained from the
patient and injected during the same session, and about
half of the injected fat remains viable for the long
term. Of the other filling materials, collagen is not
much of use today because of potential allergic reactions
and much faster absorbtion at the injected areas. The
best candidates for filler materials are those patients
with thin, dry and light colored skins. Filler materials
and fat injections are also used in augmenting both
the upper and lower lips and upper cheek regions as
well.
Technically, filler materials and fat are injected just
below the skin using a very thin needle under local
anesthesia.
As mentioned above, restylane, teosyal etc. are commercially
available products. Fat is obtained from an unwanted
area such as the lower tummy using a very thin needle
and injected during the same session, likewise under
local anesthesia.
Duration of the procedure is 5-10 minutes for the fillers
and about 30-45 minutes for the fat injection. Both
procedures are performed using local anesthesia in the
doctor’s office.
Normal daily activities can be started with almost no
down time. Temporary swelling which occurs usually disappears
in about 1-2 days after fillers and 2-4 days after fat
injections.
Main risks of the procedure are temporary swelling,
bruising, asymmetry and minor surface irregularities
and very rarely infection. Since collagen carries risks
of allergy and autoimmune reaction, and is absorbed
much faster it is not much of use today. If used at
all, collagen requires first an injection of a small
test dose to investigate the possibility of allergic
reaction. On the other hand, patient’s own fat does
not carry allergic reaction risk. Hyaluronic acid products,
likewise do not carry risks of allergic reaction other
than very rare and temporary hyperemia, eg. pinkish
swelling.
