Clean off make-up before exercising, scientists warn

The growing trend of wearing make-up at the gym or on runs is likely to be causing skin damage, according to scientists based in South Korea and the United States.

After testing the effects of applying foundation cream before exercise, the team concluded that it "can reduce skin oil, causing dryness."

"Additionally, make-up can clog pores and increase sebum production," they said, warning in the Journal of Cosmetic Dermatology that people with dry skin are likely to be worst affected by slapping on make-up before working out.
