In order to communicate a helpful treatment tip let's take a look at what is.
The pores in the skin contain sebaceous glands (oil producing glands). These glands produce sebum - an oil that lubricates your skin and hair. Most of the time, the sebaceous glands make the required quantity of sebum. With the onset of puberty and increased hormonal development the sebaceous glands are programmed to make more sebum. Further sebum results in jammed pores. Bacteria become entrapped inside the pores and increase in numbers. This intensification of bacteria can result in swelling and redness of the affected cells.
When this crops up on a large scale the result is acne. Whiteheads, blackheads and pimples in combination and in large numbers constitute acne. A clogged pore that bulges out from the skin is a whitehead. A pore that's clogged but which remains open manifests as a blackhead. When the wall of the pore opens, allowing bacteria, sebum, and dead skin cells to establish themselves under the skin resulting in a small red bump the manifestation is called a pimple. Sometimes pimples, because of the body's reaction to the bacterial infection, have a pus-filled top. Cysts are infected painful lumps that establish themselves deep in the skin.
For girls and for boys too the number one treatment tip is to minimize the chances of getting acne. All cosmetics, such as foundation, blush, eye shadow, moisturizers, and hair-care products should be oil free. Choose products labeled noncomedogenic (meaning they don't promote the formation of closed pores).
The second tip is to educate yourself about this horrible condition. Don't hang about. Buy a product now. The sooner you act the sooner you will be free of the ailment.
