AgingSkinNet Update Treating non-facial aging skin
Our faces aren’t the only parts of our body
that succumb to lifelong sun exposure and collagen breakdown. The good
news is that just as there are treatments to rejuvenate aging skin on the
face, there are treatments that can make the neck, décolleté, hands and
legs more youthful.
When we look for the reasons for our aging
skin, we need to look no further than the sun. The sun causes 90 percent
to 95 percent of the wrinkles; lines; brown, red and white discolorations;
and more on our bodies. That’s why the sun-exposed areas, including the
backs of the hands, are most prone to the imperfections.
Rejuvenating neck and chest skin
With age, many experience more and more
pronounced skin blotchiness and spider veins, called telangiectasias, on
the sides of the neck and chest. The condition, called poikiloderma, is a
result of sun damage. Areas of atrophy, which are white areas, are related
to loss of elasticity. The neck and the chest are particularly prone to
these white indentations because of the thinning skin in the region.
Chemical peels and bleaching agents applied
directly to the skin help with the pigmentation problems, including white
and brown spots. Laser and light treatments, including pulsed light
lasers, reduce redness.
A problem that often occurs is the
mismatched coloration on the neck after a person has laser rejuvenation on
the face. Laser procedures and chemical peels can lighten the skin. As a
result, dermatologists can also lighten those areas, such as the neck,
which can contrast the face, with a trichloracetic acid (TCA) peel. This
helps to blend in the areas so that the face doesn’t look strikingly
lighter than the neck and chest.
Nonablative lasers are tools dermatologists
use to treat sun damage on the neck and chest area. While lasers work by
heating and removing the top skin layers, nonablative lasers work beneath
the skin’s surface by targeting cells that absorb the light’s energy. The
underlying sources of the skin discoloration break apart from the laser’s
light and become absorbed in the body.
After a series of nonablative laser
treatments, dermatologists can reduce the signs of aging and sun damage,
including fine wrinkles, freckles and irregular pigmentation—especially on
the face, neck and chest (though it can also be used on the hands).
Patients who have these procedures can return immediately to activities
because nonablative laser therapy causes no downtime.
Photo rejuvenation is yet another approach
that uses intense pulsed light technology to correct imperfections on the
hands, neck, chest and face. The light penetrates the outer layer of skin
without causing damage and goes directly to the dilated vessels or
pigment. Patients have no downtime from the procedure but typically they
require a series of treatments for optimal results.
Botulinum toxin can be used on the chest
for diminishing wrinkles. Ask your dermatologist about its use in
décolleté smoothing to relax the muscles underneath.
Younger looking hands
Many focus on rejuvenating the skin on
their faces but forget about their aging hands. Among the most common
problems associated with aging hands are lentigines, or brown spots, which
respond to a number of treatments.
For those who don’t want to undergo any
procedures, there is the option of dermatologist-prescribed bleaching
creams, which patients rub on their hands on a regular basis for the
long-term. These work subtly to reduce the discoloration of dark pigmented
spots.
Approaches that lead to more dramatic,
faster results include the use of chemical peels, from the superficial
glycolic acid to the medium TCA peels, which work to remove dead skin
cells and stimulate the production of new skin cells. Dermatologists use
these peels on different parts of the sun-exposed body, including the
hands, to diminish age spots and lighten the skin. Cryosurgery with liquid
nitrogen can peel local areas.
Some dermatologists also use lasers, such
as the Q-switched Nd: YAG laser, to change the hands’ skin color and
remove spots. Unlike the face, hands are much easier to treat. Typically,
laser treatments correcting discolorations on the hands might take about
10 minutes in a dermatologist’s office.
The skin on the hands also tends to be
thin. Dermatologists have the option of using fat transplantation from
other areas of the body to give the hands a more youthful plumpness. This
can be done in conjunction with other procedures to lighten the
hyperpigmented (or dark) areas on the hands.
Diminishing leg veins: options in the
dermatology office
Varicose and spider veins on the legs can
worsen with age. Here, too, dermatologists have an arsenal of treatments
to bring youthfulness back to the skin on the legs.
Varicose veins are abnormally swollen or
enlarged blood vessels caused by a weakening of the vein’s walls.
Dermatologists can treat the condition with a procedure called radio
frequency closure. This involves the dermatologist inserting a small tube,
or catheter, into the varicose vein through a small puncture. The catheter
delivers radio frequency energy to the vein wall, causing it to shrink and
seal shut. Patients generally do not feel pain during the procedure and
often can return immediately afterwards to activities.
Though not as common, the endovascular
laser procedure is another technique used to treat varicose veins. The
technique involves inserting a diode laser wire or fiber directly into the
vein. The laser fiber penetrates the skin to deliver laser energy into the
vein, which heats and destroys the vein.
Dermatologists today treat leg spider
veins, which are red or bluish appearing dilated small blood vessels
located close to the skin’s surface, with lasers, which were traditionally
reserved for the face. Newer versions of laser technology, including the
Nd: YAG 1064nm, use wavelengths to penetrate the skin of the legs without
heating the pigment. This reduces the risk of burning or injury to the
skin. Typically, two to five treatments, which last about 15 minutes each,
are required to remove spider veins.
The mainstay of leg vein treatments
continues to be injection with sclerosing solutions or sclerotherapy, a
method in which the solution is injected with a very fine needle directly
into the blood vessel. All of the above procedures work in conjunction
with or in addition to its benefit. |
