I have extremely oily skin, which I choose to see as a plus: Sure, I spent my 20s fighting stubborn nodulocystic acne, but maybe all that extra oil means I'll age more slowly than my dry-skinned peers. Unfortunately, any anti-ageing effects are probably negated by the grimacing I do when someone insists my skin is oily because I don't moisturise enough. Sorry - "reactive seborrhea" is full-on bull.

Zits are unfair. We didn't ask for them, we certainly don't deserve to have them into adulthood, and it's especially insulting when you finally get a giant pimple to go away and then it comes right back a few days later.

Shining a magenta light on your face to tame acne sounds like more of a gimmick than science. But it turns out products like Neutrogena's Light Therapy Mask may actually be effective, although they aren't for everyone.

Pimples are annoying and they tend to pop up at the absolute worst time. Before you try to pop them, though, check out this video for some better ways to get rid of acne.
