Injectable Fillers in
Plastic Surgery
Improving Skin Texture
If you're considering injectables...
As we age, our faces begin to show the effects of gravity, sun exposure and
years of facial muscle movement, such as smiling, chewing and squinting. The
underlying tissues that keep our skin looking youthful and plumped up begin to
break down, often leaving laugh lines, smile lines, crow's feet or facial
creases over the areas where this muscle movement occurs.
Soft-tissue fillers, most commonly injectable collagen or fat, can help fill in
these lines and creases, temporarily restoring a smoother, more youthful-looking
appearance. When injected beneath the skin, these fillers plump up creased and
sunken areas of the face. They can also add fullness to the lips and cheeks.
Injectable fillers may be used alone or in conjunction with a resurfacing
procedure, such as a laser treatment, or a recontouring procedure, such as a
facelift.
If you're considering a facial-rejuvenation treatment with collagen or fat, this
brochure will give you a basic understanding of the procedure - when injectables
can help, how the procedure is performed, and what results you can expect. It
may not answer all of your questions, since a lot depends on your individual
circumstances. Please ask your doctor if there is anything about the procedure
you don't understand.
Knowing your options
Injected collagen and fat are primarily used to improve the appearance of the
skin's texture. They can help fill out deep facial wrinkles, creases and
furrows, "sunken" cheeks, skin depressions and some types of scars.
They can also be used to add a fuller, more sensuous look to the lips.
Injectables are usually not sufficient for severe surface wrinkles on the face,
such as multiple vertical "lipstick lines" that sometimes form around
the mouth. Instead, your plastic surgeon may suggest a resurfacing technique,
such as chemical peel, dermabrasion or laser treatments. Rather than filling in
facial lines, resurfacing methods strip away the outer layers of the skin to
produce a smoother appearance.
Deep folds in the face or brow caused by overactive muscles or by loose skin may
be more effectively treated with cosmetic surgery, such as a facelift or
browlift. Injectables are sometimes used in conjunction with facial surgery
procedures; however, injectables alone cannot change facial contour the way
surgery can.
Keep in mind that a plastic surgeon is a specialist that can offer you the full
gamut of the most advanced treatments ranging from cosmetic surgery, refinishing
techniques, laser therapy, injectables and the use of other fillers. You and
your surgeon may determine that a single procedure or a combination of
procedures is the best choice for you.
ASPS brochures are available on chemical peel, dermabrasion, laser treatments,
facelift and browlift. If you and your doctor think that one of these other
procedures might be more appropriate for you, ask your plastic surgeon to
provide you with a copy.

in the laugh lines and facial creases
that often occur with aging.
A word about other types of fillers
This brochure deals with the two most commonly used types of injectable fillers,
collagen and fat. However, to a lesser extent, a number of other filler
materials are also being used for facial-rejuvenation purposes. They include:
Fibril, a gelatin powder compound that's mixed with a patient's own blood and is
injected to plump up the skin (similar to injectable collagen); and Gortex, a
thread-like material that is implanted beneath the skin to add soft-tissue
support.
Each of these options has its own set of risks and benefits. If you're
considering any of these alternative filler treatments, tell your doctor.
What to expect from treatment
The most important fact to remember about injectable fillers is that the results
are not permanent. Injected material is eventually metabolized by the body. You
should not expect the same long-lasting results that may be gained from cosmetic
surgery.
In some individuals, the results may last only a few weeks; in others, the
results may be maintained indefinitely. Researchers believe that age, genetic
background, skin quality and lifestyle as well as the injected body site may all
play a role in the injected material's "staying power." However, the
precise reason for the variation of results among patients has yet to be
identified.
If you've had short-lived results from fat injections, you shouldn't necessarily
assume that collagen injections will work better for you. And, conversely, if
you've had disappointing results from collagen, don't assume that injected fat
is the answer. Although it's true that some individuals' bodies are more
receptive to one substance than the other, others may find that neither
substance produces long-lasting results. Sometimes one substance may work better
than the other for a specific problem.
Risks related to injectables
When injectables are administered by a qualified plastic surgeon, complications
are infrequent and usually minor in nature. Still, individuals vary greatly in
their anatomy, their physical reactions and their healing abilities. The outcome
of treatment with injectables is never completely predictable.
Collagen: Allergic reaction is the primary risk of collagen. To help
determine if you are allergic to the substance, your surgeon will perform an
allergy skin test about a month before the procedure. After the test is
performed, the test site should be watched carefully for three or four weeks, or
as long as your surgeon advises. Any sign of redness, itching, swelling or other
occurrences at the test site should be reported to your surgeon.
Risks not necessarily related to allergies include infection, abscesses, open
sores, skin peeling, scarring and lumpiness, which may persist over the treated
area. Reports of these problems are very rare.
Fat: Allergic reaction is not a factor for fat because it's harvested
from a patient's own body. However, there is still a small risk of infection and
other infrequent complications.
Planning for treatment
Facial rejuvenation is very individualized. That's why it's important to discuss
your hopes and expectations with a board-certified plastic surgeon who has
experience with many different types of surgical and non-surgical facial
procedures.
In your initial consultation, your plastic surgeon will evaluate your face - the
skin, the muscles and the underlying bone - and discuss your goals for the
surgery. Your doctor will help you select a treatment option based on your goals
and concerns, your anatomy and your lifestyle.
Your surgeon will ask you about your medical history, drug allergies, and check
for conditions that could cause problems, such as active skin infections or
non-healed sores from injuries. Collagen injections are generally off limits for
pregnant women, individuals who are allergic to beef or bovine products,
patients who suffer from autoimmune diseases, and those who are allergic to
lidocaine (the anesthetic agent contained in the syringe with the collagen
material). For more specific information about the contraindications and risks
of collagen use, ask your doctor for the manufacturer's brochure for patients.
Insurance usually doesn't cover cosmetic procedures. However, if your injectable
treatment is being performed to treat a scar or indentation from an accident or
injury, you may be reimbursed for a portion of the cost. Check with your
insurance carrier to be sure.
Where your treatment will be performed
Injectables are usually administered in a surgeon's office-based facility. If,
however, you are being hospitalized for a facelift, necklift, browlift, or any
other procedure, your injections may be administered in the hospital as well.
Types of anesthesia
Collagen: Because the anesthetic agent lidocaine is mixed in with
collagen, additional anesthetic is usually not used. However, if you are
especially sensitive to pain, your doctor may use a topical cream anesthetic or
a freon spray to numb the injected area. Or, you may elect to have an injected
local anesthetic or sedative drugs.
Fat: Both the donor and recipient sites are numbed with local anesthesia.
Sedation can be used as well. If you elect to use sedation, be sure to arrange
for a ride home after your treatment.
The Treatments
Collagen
Collagen is a naturally occurring protein that provides support to various parts
of the human body: the skin, the joints, the bones and the ligaments. Injectable
collagen, patented by the Collagen Corporation under the trade names Zyderm and
Zyplast, is derived from purified bovine collagen. The purification process
creates a product similar to human collagen. Injectable collagen received
approval from the Food and Drug Administration in1981. It is produced in various
thicknesses to meet individual patient needs.
Collagen is used primarily to fill wrinkles, lines and scars on the face and
sometimes the neck, back and chest.
The procedure: Treatment with collagen can begin after a skin test
determines that you're not allergic to the subsstance. The collagen is injected
using a fine needle inserted at several points along the edge of the treatment
site. If a local anesthesia has not been used, you may feel some minor stinging
or burning as the injections are administered.

Years of squinting and other facial
muscle movements can take their toll
on the eye area, leaving crow's feet
and other noticeable lines
Since part of the substance is salt water that will be absorbed by the body
within a few days, your doctor will slightly overfill the area. You may be asked
to hold a hand mirror during the procedure to help your doctor decide when
you've had enough.
After treatment: Immediately following treatment, you may notice some
minor discomfort, stinging or throbbing in the injected area. Occasionally some
bruising or swelling will occur, but it is usually minor. Any redness that
appears in the injected site usually disappears within 24 hours. However, in
some individuals, particularly fair-skinned patients, this redness may persist
for a week or more. Tiny scabs may also form over the needle-stick areas; these
generally heal quickly.
No bandaging is needed and you are free to eat, drink, and wear makeup with
sunblock protection shortly thereafter. There may be some temporary swelling and
redness in the treated area which should dissipate within a few days. If these
symptoms persist, contact your surgeon.
After treatment, the skin around the eye
area appears smoother and more taut.
Results: As stated earlier, the duration of results from collagen
injections is variable. Collagen's longevity depends on the patient's lifestyle
and physical characteristics as well as the part of the body treated. In
general, the injected material is likely to disappear faster in areas that are
more affected by muscle movement.
Your doctor can help you determine how long you can go between treatments to
best maintain your results.
Fat
In the medical world, the fat-injection procedure is known as autologous fat
transplantation or microlipoinjection. It involves extracting fat cells from
the patient's abdomen, thighs, buttocks or elsewhere and reinjecting them
beneath the facial skin. Fat is most often used to fill in "sunken" cheeks or laugh lines between the nose and mouth, to correct skin depressions or
indentations, to minimize forehead wrinkles and to enhance the lips.
The procedure: After both the donor and recipient sites are cleansed and
treated with a local anesthesia, the fat is withdrawn using a syringe with a
large-bore needle or a cannula (the same instrument used in liposuction)
attached to a suction device. The fat is then prepared and injected into the
recipient site with a needle. Sometimes an adhesive bandage is applied over the
injection site.
Lines and creases that form around the
mouth are usually caused by gravity
and a breakdown of tissues beneath
the skin.
As with collagen, "overfilling" is necessary to allow for fat
absorption in the weeks following treatment. When fat is used to fill sunken
cheeks or to correct areas on the face other than lines, this overcorrection of
newly injected fat may temporarily make the face appear abnormally puffed out or
swollen.
After treatment: If a larger area was treated, you may be advised to
curtail your activity for a brief time. However, many patients are able to
resume normal activity immediately. You can expect some swelling, bruising or
redness in both the donor and recipient sites. The severity of these symptoms
depends upon the size and location of the treated area. You should stay out of
the sun until the redness and bruising subsides - usually about 48 hours. In the
meantime, you may use makeup with sunblock protection to help conceal your
condition.
The swelling and puffiness in the recipient site may last several weeks,
especially if a large area was filled.
The lower face appears firmer and
smoother after treatment with injectables.
Lines around the mouth are filled in and
nearly imperceptible.
Results: The duration of the fat injections varies significantly from
patient to patient. Though some patients have reported results lasting a year or
more, the majority of patients find that at least half of the injected fullness
disappears within 3-6 months. Therefore, repeated injections may be necessary.
Your doctor will advise you on how to maintain your results with repeat
treatments.
Your new look
If you're like most patients, you'll be very satisfied with the results of your
injectable treatments. You may be surprised at the pleasing results that can be
gained from this procedure.
With regular follow-up treatments,
your refreshed look can be easily
maintained.
