New Survey and Studies Debunk the Myths and Misconceptions
About This Common Skin Condition
NEW ORLEANS, Feb. 21 /PRNewswire/ -- Have you ever washed your face more
than twice a day to clear up your skin? Do you avoid chocolate and greasy
foods in the hopes that when you look in the mirror, you won't see another
blemish? Have you ever drank more water, or avoided or increased your
exercise to prevent acne flare-ups? If you answered yes to any of the above
questions, you're not alone.
Acne is one of the most common skin disorders in the United States,
affecting nearly 85 percent of all people. While the variety of effective
acne treatments continues to grow, so does the number of myths about how to
control the condition.
Speaking today at the 63rd Annual Meeting of the American Academy of
Dermatology, dermatologist Alexa Boer Kimball, M.D., assistant professor of
dermatology at Harvard University, Boston, Mass., discussed a recent survey
that determined which acne myths still persist among young adults as well as
several studies on the scientific accuracy of these beliefs.
"Although new acne treatments are developed every day, a cure for acne has
not yet been discovered. As such, many patients choose to self-treat or
experiment with unconventional treatments," stated Dr. Boer Kimball. "Yet
many of these treatments are based on anecdotal observations and have not been
rigorously tested by science. The survey indicates that these myths are still
affecting how patients care for their acne."
Myth: Poor Hygiene Worsens Acne
The relationship between face washing and acne has always been greatly
misunderstood, with most individuals believing that dirt and poor hygiene
contribute to acne. In fact, a recent survey conducted at Stanford University
asked participants about what they thought made acne worsen, and the majority,
91 percent, mentioned poor hygiene. "If a patient believes that dirty skin
causes acne, they logically conclude that washing their face more often will
improve their acne," said Dr. Boer Kimball. "But dermatologists caution
patients against washing too often, as the resulting irritation can exacerbate
their acne."
To determine the scientific validity of this myth, the effects of face
washing on acne were recently studied at Stanford University. A group of
twenty-four males washed their faces twice a day for two weeks using a mild
over-the-counter facial cleanser. Then the participants were randomly
selected to wash their faces either once, twice or four times a day for
another six weeks. The study found that washing the face either once, twice
or four times daily did not significantly change the appearance or condition
of acne, and determined that the positive effects of increased facial
cleansing are minimal at best. Dermatologists continue to recommend washing
the face twice daily to maintain good overall skin health.
Myths: Exercise Can Clear Acne or Exercise Can Worsen Acne
The relationship between acne and exercise continues to show high levels
of individual variability. Some believe that exercise and sweating can help
clean out the pores, especially on the chest and back; while others note that
their skin worsens when they exercise, especially those who use special
equipment that rubs against their skin.
In another study conducted at Stanford University of patients with acne,
it was determined that exercise-induced sweat does not have a significant
positive or negative influence on acne of the chest and back. Twenty-three
male participants were assigned to three groups: no exercise, regular exercise
followed by immediate showering and regular exercise followed by delayed
showering. The number of acne lesions on the chest and back were counted over
a two week period and no difference was noted between the three groups.
"Based on the finding of this study, regular exercise can be encouraged for
patients with acne," stated Dr. Boer Kimball. "But they should avoid tight-
fitting clothing and equipment. If tight-fitting equipment is required, it
should be cleaned on a regular basis."
Other Acne Myths
While misconceptions about facial hygiene and exercise are still the most
commonly recognized acne beliefs, the Stanford survey also found that
respondents believed that poor diet and decreased sleep can negatively affect
acne. In addition, more than 80 percent of participants believed that
increased stress, touching the face and popping pimples exacerbated the
condition. Among male and female participants, the only differences noted
were that more females believed that increased stress could worsen acne and
that drinking more water would improve the quality of their skin. The study
also found that some beliefs that were previously popular about acne were no
longer viewed as true, including the idea that tanning improves the appearance
of acne.
"What this survey and these studies have shown is that substantial
differences still exist between popular belief and scientific support, yet
this does not change the way patients attempt to care for their acne," stated
Dr. Boer Kimball. "It is important for anyone who is affected by acne to seek
the help of a dermatologist who can diagnose and provide treatment options
that are specific to the patient's skin type to effectively address the
condition."
