Acne is something most of us have experienced at one time or
another. As many as three out of four teenagers have experienced it
to some extent. It is most prevalent during adolescence because
hormonal changes stimulate the sebaceous glands (oil glands) into
producing more sebum (oil), increasing the chance of acne. While
most people outgrow acne in their late teens or early twenties, many
continue to be affected much longer. Aggravation of acne in later
life may occur with menstrual periods, use of birth control pills,
use of oil-based products and stress.
What causes acne?
Acne occurs when the oil produced by sebaceous glands does not
reach the surface of the skin but is trapped in tiny pores or
follicles. This plug may close off the pore, causing the follicle
wall to bulge, which creates a whitehead. If the pore stays open,
the top surface of the plug may become darkened, causing a
blackhead. In both cases, the bacteria, P acnes, thrives in the
clogged follicles. When the bacteria and pus leak from the follicle
into the surrounding tissue, pimples are formed.
You may have heard that "blackheads are dirt" ; "only teens have
acne" ; "junk foods cause acne" ; or "it will just go away by
itself." These and other myths have prevented many from seeking the
appropriate acne treatment for years.
Your doctor will determine the severity of your acne and may
select one or more treatments that are best for you. The basic steps
of acne control may include topical antibacterials and antibiotics,
oral antibiotics, comedolytics (such as Retin-A(tm)), sebostatics
(such as Accutane(tm)), astringents and exfoliants.
Recent advances in device-based acne treatments include:
* ClearLight(tm) system which uses a high intensity blue-light
designed specifically to kill the bacteria responsible for acne
vulgaris.
* Micro-Dermabrasion with and without vitamin C (ascorbic acid).
Common acne scar treatments
Injections with Collagen,
Cymetra(tm), Dermalogen(tm), Restylane(tm), and Hylaform(tm) are
good treatments for shallow and deep acne scars. These fillers can
be injected into the area of the scar, smoothing depressions.
Results are immediately apparent. Patients usually require touch-up
treatments every six months to two years.
Dermabrasion is often
recommended for severe acne scars and works well on both raised and
grooved areas of the skin. The skin is first treated with an
anesthetic, and the top layer of the skin is then "sanded down" with
a wire brush or diamond burr. Seven to ten days later, the skin
forms a new, smoother layer. Patients can expect full recovery in
about six weeks.
Micro-Dermabrasion can
be likened to a superficial "skin polishing" using micro-crystals
vacuumed over your skin's surface to remove damaged skin cells.
These gentle treatments can provide noticeable improvement to acne
scars. The treatments are progressive and are applied through a
course of weekly sessions.
Chemical Peels use a
chemical solution to burn away the fine outer layers of the skin.
The solutions are available in several strengths, depending on the
degree of peeling desired. Healing can take from three days to three
weeks. A new, smoother layer of skin is then formed.

non-ablative laser treatments do not require anesthesia, as they are
not painful and there is no downtime. Most patients receive a series
of about five treatments. Depending on the type of acne scar,
improvement can be dramatic. The improvement is gradual and
continues to improve even after the treatment stops.
Laser resurfacing
Laser resurfacing gives your
physician precise control as the procedure gently vaporizes the
damaged or acne-scarred skin to reveal the smooth, fresh skin
underneath. Scars are removed in a precise, rapid, bloodless fashion
achieving excellent results. Laser scar removal can be performed
with local anesthesia if limited areas are treated, while full face
resurfacing is usually performed with the administration of
intravenous sedation by an anesthesiologist. Both procedures may be
performed in your doctor's office.
Treating acne scars
Millions of people suffer from varying degrees of acne scars.
Even a mild case of adolescent acne can leave permanent scars
throughout adulthood. In addition to physical trauma, for many, acne
scars can also have adverse psychological effects.
Fortunately, severe and mild acne scars can be successfully
treated with a range of non-surgical procedures.
