If you currently suffer from acne, and try to find a cure- don't worry. Acne is a common condition, usually prevalent during puberty. It is caused by skin pores being clogged with sebum, which is the skins normal lubricant. During puberty, hormones are produced in very high quantities and this, in turn, causes the skin to overproduce sebum.
There are several ways that can help you cure acne.
First, apply a high standard of personal hygiene. Wash your face daily, with mild soap and warm water, to get rid of the excess sebum. Find out which soaps are particularly recommended for people with acne, buy them, and use them as often as needed.
You can also find many over the counter lotions that contain an anti-bacterial agent, like benzoyl peroxide. This will decrease oil and bacteria.
Resist the temptation and don’t pop pimples. This might spread the infected material further over the skin, and cause swelling and possibly even scars.
Always wash your hands before touching your face, and generally try not to touch your face often.
If you have acne on your body, for example on your back, wear loose clothes. This will enable your skin to breath, and prevent irritation.
If you use some kind of cosmetic lotions other then for acne treatment, make sure that these lotions or creams are classified as non-comedogenic, which means that they do not clog your pores. These are generally lotions that are very gentle to the skin, and are lightly scented or have no scent at all.
If you are really worried about your acne, visit a dermatologist. He can give you support and advice, based on your particular circumstances.
Finally, if you're taking a prescription acne medication, make sure you finish the entire prescribed dose, even if you notice that your skin has become much clearer. Finishing medication too early might increase the chance of another acne breakout.
