Chemical peel uses a chemical solution to improve and
smooth the texture of the facial skin by removing
its damaged outer layers. It is helpful for those
individuals with facial blemishes, wrinkles and uneven
skin pigmentation. Phenol, trichloroacetic acid (TCA)
and alphahydroxy acids (AHAs) are used for this purpose.
The precise formula used may be adjusted to meet each
patient's needs. Although chemical peel may be performed
in conjunction with a facelift, it is not a substitute
for such surgery, nor will it prevent or slow the aging
process. This brochure provides basic information about
certain types of chemical peel treatments and the
results you might expect. It won't answer all your
questions, since a lot depends on your individual
circumstances. Once you and your plastic surgeon have
decided on a specific peel program, be sure to ask about
any details that you do not understand.
Deciding if chemical peel is right for you Chemical peel
is most commonly performed for cosmetic reasons -- to
enhance your appearance and your self confidence.
Chemical peel may also remove pre-cancerous skin
growths, soften acne facial scars and even control acne.
In certain cases, health insurance may cover the peel
procedure. Be sure to check your policy and contact your
insurance company before the procedure is performed.
Alphahydroxy acids (AHAs), such as glycolic, lactic, or
fruit acids are the mildest of the peel formulas and
produce light peels. These types of peels can provide
smoother, brighter-looking skin for people who can't
spare the time to recover from a phenol or TCA peel. AHA
peels may be used to treat fine wrinkling, areas of
dryness, uneven pigmentation and acne. Various
concentrations of an AHA may be applied weekly or at
longer intervals to obtain the best result. Your doctor
will make this decision during your consultation and as
the treatment proceeds. An alphahydroxy acid, such as
glycolic acid, can also be mixed with a facial wash or
cream in lesser concentrations as part of a daily
skin-care regimen to improve the skin's texture.
Trichloroacetic acid (TCA) can be used in many
concentrations, but it is most commonly used for
medium-depth peeling. Fine surface wrinkles, superficial
blemishes and pigment problems are commonly treated with
TCA. The results of TCA peel are usually less dramatic
than and not as long-lasting as those of a phenol peel.
In fact, more than one TCA peel may be needed to achieve
the desired result. The recovery from a TCA peel is
usually shorter than with a phenol peel.
Phenol
is the strongest of the chemical solutions and produces
a deep peel. It is used mainly to treat patients with
coarse facial wrinkles, areas of blotchy or damaged skin
caused by sun exposure, or pre-cancerous growths. Since
phenol sometimes lightens the treated areas, your skin
pigmentation may be a determining factor as to whether
or not this is an appropriate treatment for you. Phenol
is primarily used on the face; scarring may result if
it's applied to the neck or other body areas.
All
chemical peels carry some uncertainty and risk. Chemical
peel is normally a safe procedure when it is performed
by a qualified, experienced plastic surgeon. However,
some unpredictability and risks such as infection and
scarring, while infrequent, are possible.
AHA
peels may cause stinging, redness, irritation and
crusting. However, as the skin adjusts to the treatment
regimen, these problems will subside.
With a
TCA peel, your healed skin will be able to produce
pigment as always; the peel will not bleach the skin.
However, TCA-peel patients are advised to avoid sun
exposure for several months after treatment to protect
the newly formed layers of skin. Even though TCA is
milder than phenol, it may also produce some unintended
color changes in the skin.
With a
phenol peel, the new skin frequently loses its ability
to make pigment (that is, tan). This means that not only
will the skin be lighter in color, but you'll always
have to protect it from the sun. Phenol may pose a
special risk for patients with a history of heart
disease. It's important that you make your surgeon aware
of any heart problems when your medical history is
taken.
It is
also possible that phenol will cause some undesired
cosmetic results, such as uneven pigment changes.
Certain modified phenol peels are gentler and may be
preferred in some circumstances.
