Even the stars have gone through some of the same problems that we do.

Acne and blemishes happen to all of us. When Katy Perry was a teen she had acne and it left some scars on her face which she now covers up with make-up.

Katy has never denied the fact that she had issues with acne, and that is why one facial cream company has chosen her as their cover girl for their creams. At least Katy can say that her zits paid off in the long run - she will earn 4 million dollars for doing ads for this company!

The ad will come out in 58 countries this mwezi and so soon we will be able to see Katy giving us some tips on how to clear up problem skin.
