If you still need convincing, consider this: The more rock-star foods in your repertoire, the more diseases you'll fend off, the better you'll look, and the stronger you'll feel. That means less cancer, diabetes, and heart disease, as well as more energy, a tinier tummy, and a better night's sleep.
Avoid going out in dust, dirt and sun exposure because it causes pimples on the face. Excess exposure to sunlight is another important reason of the pimples on forehead. The formation or over activation of oil glands is the cause of the production of pimples on the nose.
Pimples start popping up around puberty, when the oil glands in skin become active. What happens is something like this: skin naturally sheds dead skin cells, which get glued together by all this new sebum (aka oil) that's being produced by the oil (aka sebaceous) glands.
