      A pimple, also known as a zit or spot is a small papule or pustule; small skin lesions or inflammation of the skin – they are oil glands (sebaceous glands) that are infected with bacteria, become inflamed, and then fill up with pus.

      Here are 4 Simple tips that could help you get rid of pimples.

      1. Keep you hands off of your face. This is extremely important. Unless your hands have just been washed do not touch your face with them. All day, your hands come in contact with bacteria and oils that can and will spread your acne and make it worse. Don’t sit there feeling them and popping them all day long.

      2. Wash your face gently with Warm water and a soft wash cloth 2-3 times a day. Do not use a tough wash cloth. Once this is done you can then apply your exfoliant, which works well in the fight against acne.

      3. Baby Powder can work well in drying out your pimples and getting rid of them. Remember to wash your face first though.

      4. Eat plenty of nutritional foods that are high in fiber, iron, protein, and zinc. Also remember to drink plenty of water as It helps flush a lot of toxins out of your body.

      There are particular bacteria that are associated with spots, for example Proprionibacterium acnes (it’s even named after it’s spot forming properties). Antibiotics can be used to get rid of these bacteria either by taking tablets or applying them straight to the skin. These are used for months or years so it’s best not to take tablets as they will kill all the bacteria in your body, even the good ones that help you digest food and protect you from the bad bacteria.

      We’re developing another method to control the bacteria that cause spots in my lab. We use chemicals that react with light to kill the bacteria. Unlike with antibiotics, there is little chance of bacteria becoming resistant to these chemicals.
