Acne, of course, has long been known as a teenage scourge, although pimples can also affect older people. Feldman and his colleagues looked for research into the possible effects of acne on quality of life and mental health in adolescents. They determined that 16 studies were worthy of inclusion in their review; some of the studies included both teenagers and older people.
The review was published in the Dermatology Online Journal.
Overall, it says, the studies suggest that acne "can negatively affect quality of life, self-esteem and mood in adolescents." Acne is also linked to higher rates of anxiety, depression and suicidal thoughts.
In particular, one study found that 9 percent of teens with acne showed signs of depression, a rate that is three to four times higher than in the general population.
The cause-and-effect issue is a tricky one: the studies don't prove that acne directly causes these problems; it could conceivably be the other way around.
However, "we're not anticipating that depression cause
