There are many reasons for the cause of Acne. Although everyone is different, acne is usually caused by the build up of oil and dead skin in a pore. This build up of oil and dead skin is caused because of the following,
1. Natural hormones - These are particularly active in your teens.
2. Family background - If you have acne, your kids are more likely to have it too.
3. Bacteria - Bacteria can easily infect oil glands and pores and grow very quickly.
4. Plugged skin - Lots of skin cells can close the oil glands or pores, creating blackheads or whiteheads.
