A
High-Tech Weapon in the Fight Against Aging Skin
Vaporized
Normally this is
not a good thing where humans are concerned. In science
fiction films the characters vaporized by a laser simply
disappear. Patients opting for cosmetic laser surgery,
however, suffer a less severe fate: Only their wrinkles
and other skin imperfections disappear.
In recent years,
lasers have shed their science fictional image to become
a surgeon's and dermatologist's most promising weapon in
the fight against aging skin. According to the American
Academy of Cosmetic Surgery in Chicago, nearly 170,000
Americans, men and women, underwent laser resurfacing of
the face in 1998, up from 138,891 in 1996--a 64 percent
increase. That's nearly twice the number of the more
traditional surgical facelifts performed in the same
year.
Laser resurfacing
is a very controlled burning procedure during which a
laser vaporizes superficial layers of facial skin,
removing not only wrinkles and lines caused by sun damage
and facial expressions, but also acne scars, some folds
and creases around the nose and mouth, and even
precancerous and benign superficial growths. In a sense,
the laser procedure creates a fresh surface over which
new skin can grow.
While the Food and
Drug Administration does not regulate how surgeons carry
out these procedures, it is responsible for clearing
lasers for marketing for the uses requested by the
device's manufacturer.
Lasers in
Cosmetic Surgery
Since their 1958
discovery, lasers have become a powerful industrial tool,
but their applications in medicine have been truly
revolutionary. One reason, says Richard Felten, a senior
reviewer in FDA's Center for Devices and Radiological
Health, is that lasers used as surgical tools can cut
through tissue without causing excessive bleeding. In
fact, lasers actually can coagulate tissue to stop
bleeding. "That's something a knife can't do,"
Felten says. Also, for many internal procedures, surgeons
can get the laser's energy to reach areas within the body
more easily than with a scalpel. And finally, the
wavelengths of the laser light itself lets surgeons use
the device selectively on very specific types of tissues,
such as port wine stains or hair follicles, without
affecting nearby tissue. (See "Other Laser Treatments")
But using lasers
for facial skin resurfacing was discovered almost by
accident, Felten says. In the course of treating acne
scars with a laser, surgeons noticed that after
resurfacing the skin around the scar to make the scar
less visible, small adjacent wrinkles were greatly
diminished.
"Resurfacing
is very appealing to people," says Stephen W.
Perkins, M.D., president of the American Academy of
Facial Plastic and Reconstructive Surgery and of the
Meridian Plastic Surgery Center of Indianapolis, Ind.,
"because it is a way of refreshing the skin's
surface and getting a new layer of non-sun damaged and
more youthful skin."
Collagen is a key
fibrous protein in the skin's connective tissue, and it
helps give the skin its texture. Natural aging and such
factors as sun damage and smoking help break down the
collagen layer so that the skin's once smooth surface
develops wrinkles. New, more youthful collagen actually
forms after laser treatment, says A. Jay Burns, M.D.,
partner in the Dallas Plastic Surgery Institute and
assistant professor of plastic surgery at the University
of Texas Southwestern Medical School.
Laser resurfacing
can often make patients look 10 to 20 years younger, and
the results can last for eight to 10 years, says Tina
Alster, M.D., director of the Washington Institute of
Dermatologic Laser Surgery in the nation's capital. But
she warns that after surgery, patients must avoid
sunbathing and destroying their skin again. Patients can
have a repeat treatment after one year, but usually the
first procedure is so successful a follow-up is not
needed.
Lasers cannot
rejuvenate skin on other parts of the body nor can laser
treatment lift or remove sagging jowls or smooth out
"crepey" or sagging neck skin. These conditions
only respond to traditional cut-and-stitch surgical
methods.
Is
Resurfacing for You?
Not everyone makes
an ideal candidate for laser resurfacing, Perkins
explains. "Certain people with very sensitive skin
cannot tolerate the medications and lubricants used on
the skin during healing." Perkins also feels that
the darker-skinned ethnic groups are not candidates
because the laser treatment alters the color of skin too
dramatically and unpredictably. Alster, on the other
hand, believes that in the hands of a very experienced
surgeon, people with darker skin tones, although not
ideal candidates, can benefit from surgery.
Alster warns that
anyone not mentally prepared for resurfacing or who
expects instant results is not a good candidate.
"This is not easy in-easy out surgery," she
says. "Potential patients have to realize that there
will be bruising and swelling and they will be holed up
in the house for seven to 10 days," she says.
"They will have a crusty, oozy, bruised, scabbed,
raw-appearing face." Further, they should not expect
unflawed skin. "I can't deliver that," she
says. "I am not able to give unlined, unscarred
skin." Patients, however, can expect a 50 percent or
greater improvement.
They must also plan
on at least 10 days of healing before applying any
makeup. For satisfactory healing, that means following
rigorous after-care treatment, including proper skin
cleansing, the application of a skin lubricant, and the
frequent changing of dressings.
What Are
the Risks?
As with any medical
procedure, patients may experience certain
complications--most temporary--including a prolonged
redness of skin, tenderness, easy flushing, and some
pigmentary changes, like hyperpigmentation, when the skin
appears darker than normal, says Rox Anderson, M.D.,
director of the Laser Center at Massachusetts General
Hospital in Boston.
Other risks are
more serious, and possibly permanent, including
hypopigmentation, or lightening of the skin.
"Somewhere between one to two years after treatment
it becomes clear that there is a permanent lightening of
the skin color where the resurfacing was done," he
says.
And scarring may
occur in about 2 percent of the cases, he adds, from poor
postoperative care, during which time an infection may
develop. Or a surgeon may go too deep during the
procedure, creating an injury the skin cannot repair,
says Alster.
Consider the case
of Anne Jones (not her real name) in semi-rural
Mississippi, a stay-at-home mom and a doctor's wife.
Wanting to remove some mild acne scars, she went to a
well-respected local plastic surgeon, but after a
five-month recovery period, Jones realized that something
had gone very wrong. "He had just burned my
face," she says. It was red, with scar tissue all
over, she adds.
Eventually, Jones
went for help to an ophthalmologist who had extensive
laser knowledge--many ophthalmologists use lasers for
corrective eye surgery. He took one look at her and
exclaimed, "Oh, I am so sorry this has happened to
you." He told her that the surgeon had been too
aggressive and had not used the right settings, so that
her skin had retained too much heat and had been severely
burned.
Because both
qualified and unqualified practitioners are flooding the
cosmetic laser surgery field, consumers may face some
real hazards. "All of a sudden, there's widespread
use of lasers by unqualified people," says Perkins,
who notes that some laser manufacturers are so eager to
sell their products that they stage one- or two-day
meetings, or courses, for training. That means that even
dentists, obstetricians, gynecologists, and family
doctors are now offering laser surgery, says Alster.
"The person
planning to do laser surgery must understand the basic
physics of how laser energy is absorbed by tissue and how
tissue responds," warns FDA's Felten. "Then
that person should go where the surgery is performed and
watch a skilled surgeon use the equipment." Besides
that, says Anderson, the best people to work with lasers
on skin conditions are the professionals who best
understand skin and surgery of the skin: dermatologists
and plastic surgeons.
"Sometimes
people may choose the wrong laser, or a surgeon may
believe more is better, which can lead to significant
burning," says Alster. And some operators don't know
they must keep wiping off the partially desiccated skin
or that they must keep moving the hand holding the laser
instrument during the procedure.
To date, no
national policy exists for credentialing those planning
to practice laser surgery. Felten says FDA is responsible
for granting individual manufacturers permission to
market their lasers for the specific indications
requested. FDA also often recommends training needed to
operate the lasers.
But credentialing
is a state function, since states are responsible for the
licensing of doctors and nurses, and standards for laser
training vary from state to state.
That's bad news for
patients like Jones. Two years have passed since her
procedure and she has spent nearly $70,000 for both the
initial surgery and subsequent consultations and
corrective surgeries to remove the scarring. She says she
has partially reclaimed her life. But she bitterly
regrets undergoing the initial surgery. "I will
never look right," says Jones. "I would never
do this again."
Finding the
Best Surgeon
Selecting a laser
surgeon is just like picking a qualified doctor for any
medical treatment. "Consumers ask more questions of
auto mechanics," says Alster. "This is surgery
and with it comes inherent risks and complications. While
it is perceived as easy, it is not. When you are talking
about skin, it is harder to treat than eyes."
The Internet is a
good place to start the search. Consumers can find
thousands of Websites, including those for specialists,
laser and plastic surgery societies, and information
pages. But consumers should be wary of assuming the
accuracy of any information taken off the Internet
because the unscrupulous can put up their own Web pages
just as easily as can the qualified.
Alster suggests
interviewing several doctors and evaluating their answers
and their credentials. After all, she adds, it's the
doctor's skill that counts--the laser is just the
doctor's tool.
The next step is
crucial: asking the right questions. Alster advises
asking where the doctor has trained and if he or she owns
or rents the equipment--those who own have likely made a
commitment to training and to laser surgery. Ask to see
before and after pictures of the doctor's cases, and find
out how many different types of lasers the doctor owns
and how often each piece of equipment is used.
"There is not one laser that does everything,"
she says, cautioning patients to select a surgeon whose
practice offers more than one laser system. "One
needs to use [the right] laser for the right lesion. So
the person examining you must make the correct
diagnosis," she says. Alster herself has at least 10
different lasers in her office.
Of course, the
final decision may be difficult, since no doctor can
guarantee perfection or complete safety, but
well-informed patients with reasonable expectations may
be one step closer to younger, fresher-looking skin.
Other
Laser Treatments
Many skin
conditions respond well to laser surgery, including red
vascular lesions such as spider veins on the face,
hemangiomas, and birthmarks such as port wine stains,
says Rox Anderson, M.D., director of the Laser Center at
Massachusetts General Hospital in Boston. Lasers also are
useful for scars, warts, excessive eye folds, tattoos,
and hair removal, along with such conditions as rosacea,
brown age spots, and the brown and blue pigmented facial
lesions common to Asian skin. "Most Asians are told,
'There's no hope. Live with it,'" Anderson says. But
in one or two laser treatments, the facial lesion
vanishes. "Lasers really are magic bullets. They can
do things deep in the skin without trashing anything
else. It's not like surgery where the tools are not
microscopically specific." And most significantly,
laser resurfacing can remove precancerous lesions caused
by sun damage.
