However, 60 percent of women either do not respond to standard
acne treatments or build up a tolerance to frequently used medications. "I want to make an appeal to every woman who has not been able
to control her acne through topical treatments or antibiotics to
consult with a dermatologist soon," said Dr. Thiboutot. "There
are so many different new therapy options to chose from now that
most cases of persistent acne can be improved."
Acne in women is often related to her menstrual cycle. Women with
premenstrual acne outbreaks, especially outbreaks on the lower
face and neck, seem to respond particularly well to treatment with
medications that either reduce or block androgen production. The
androgen hormones create male traits in women such as a deepening
of the voice, an increased libido or hirsutism that causes an excessive
or abnormal growth of hair. They also stimulate the oil (sebaceous)
glands, typically found in areas where acne is common such as the
face, upper back and chest. The oil mixes with skin cells and bacteria,
causing inflammation in the skin which appears as redness, swelling
and pus -- commonly known as a pimple.
It is not yet known exactly what causes adult acne. It is important
for patients to note that acne is not caused by dirt, nor is it
related to the foods a person eats. Some types of liquid foundation
and other make-up can clog pores and aggravate acne. In addition,
hairspray, gels and other hair products that come in contact with
the skin may worsen acne blemishes. While some patients try to
conceal acne with a tan, the sun's harmful ultraviolet (UV) rays
age the skin and can cause skin cancer, wrinkles and other dermatologic
aging.
Before a dermatologist prescribes hormone therapy for a woman,
the doctor may perform a standard screening work-up that includes
two hormones -- testosterone and DHEAS (dehydroepiandrosterone
sulfate). It is also important that the patient stop taking oral
contraceptives for at least one month before any tests are performed
because birth control pills can suppress androgens.
The basis of hormonal therapy is the birth control pill. The medications
most effective in controlling acne contain a hormone called progestin
with low androgenic activity (with generic pharmaceutical names
such as norgestimate or desogestrel) in combination with 35 micrograms
of ethinyl estradiol, an estrogen.
"As with any therapy, there are risks and rewards. The risks of
hormonal therapy require regular breast and pelvic exams to guard
against the increased risk of certain types of cancers. It is vitally
important that dermatologists work with the patient's gynecologist
to determine the most appropriate treatment and follow-up especially
in women over the age of 40 or those who might be smokers," Dr.
Thiboutot noted.
In addition to consulting on cases of acne in adult women, dermatologists
and gynecologists often consult on cases of young women with acne.
It is common for a dermatologist to be the first to consult with
a teenage girl who comes into the office with acne that is actually
a symptom of polycystic ovary disease. Both acne and polycystic
ovary disease are caused by an imbalance in androgen hormones.
It is important for dermatologists to work closely with the young
patient's gynecologist to reduce the risks of infertility, cardiovascular
disease and insulin-resistant diabetes. The identification of polycystic
ovary disease is an important contribution to the long-term health
of these young patients.
"Hormonal therapy is a good treatment for many teenage and adult
women," Dr. Thiboutot said. "It is used less often than it could
be because there are so many options to choose from. The patient
should realize it is a good adjunct therapy."
Most acne treatments require prolonged care ranging from months
to years depending upon the individual. Even after the acne is
controlled, ongoing therapy is typically required to maintain the
positive results.
