Why is it that when you turn a certain age you get spots on you face?
In: Biology
Your skin is covered with tiny holes that itsy bitsy hairs grow from. Some of these holes also emit small amounts of a home-grown skin lotion, and under normal circumstances the little lotion holes shed used-up cells the same way the rest of your skin does. So they stay clean and unplugged.
But things can go wrong. Sometimes the lotion holes get plugged up— maybe the used-up cells inside them aren’t falling off fast enough, or there’s too much lotion, or the skin swells and blocks the holes, or something physically keeps the holes shut, or maybe they were too small or the wrong shape to start with. No one yet knows exactly why this happens to some people and not others. But if it does, small infections can start in the holes, and these infections either burst outward or deepen and get even worse. That’s acne in all its forms. Often the person outgrows it. But not always.
