Certain eating habits, high levels of stress and exposure to pollution are among the greatest factors associated with acne, researchers say.

Nearly 28 million Americans are affected by the skin condition eczema, and for some it may become so chronic and severe they consider suicide, new research shows.
A new review of data from 15 studies, involving over 300,000 people, found that those with eczema had a 44 percent higher risk of suicidal thoughts compared with people without the immunological disease.

As if the start of a new school year isn't stressful enough, many teens may find their acne worsens when classes start, a skin doctor says.

Though psoriasis is not contagious, many Americans shun people with the skin condition, new research indicates.
The study included a cross-section of about 400 Americans who viewed images of people with visible psoriasis. Large numbers wrongly thought psoriasis was contagious or only affects the skin, and about one-third said they wouldn't want to invite people with the condition into...
Acne and adolescence go hand in hand. But researchers say the skin lesions might become a torment of the past if preliminary tests of an experimental vaccine pan out.
So far, the vaccine has only been tried on animals and human skin samples. It uses antibodies to target a toxin secreted by the bacteria responsible for acne, explained study author Chun-Ming Huang. He's a professor of d...
