Scientists find stress linked to acne

[Tatiana]

BERLIN, GERMANY (CNN) --It's a common experience: You're under stress
because of an exam, your job or just juggling your everyday activities
-- and you develop acne.

Was the outbreak caused by stress? Until now, no scientific evidence
has supported that it is.

But German researchers say they have found a major indication that
stress and acne, as well as other skin conditions, are linked.
