There are several different factors that affect the formation and distribution of acne. Oil, dirt, food, allergies, skin type and follicle size all play a part in the development of acne blemishes. Acne medicines focus on one or several of these factors.

If you are plagued by acne you are more than aware of the overwhelming number of products that are available for treatment - both over the counter and as prescription medications. With all of these medications how do you decide which is best for your skin type, sensitivity and your age?

The acne medicine you chose should be determined by the type of acne you have, your skin type and the sensitivity of your skin. Most products require at least 2-3 weeks before you see improvement because of the physiological response of the skin. It can take up to 3 months before your skin clears completely if the acne medicine is successful.

If your acne is mild to moderate then over the counter acne medicines may be best for you. They contain drying agents to decrease the amount of oil that clogs the pores and may also have a mild antibiotic to clear the bacteria that makes the acne worse. If you have severe acne, however, you should seek the advice of a dermatologist. Improper acne medicines can actually make the problem worse.

Since hormone levels sometimes have an effect on the production of oil, birth control pills are used. They are mostly used to decrease the activity of androgens, the male sex hormones that are responsible for producing oil. Birth control pills work to correct hormonal imbalances.

For severe cases of acne Accutane or Isotretinoin may be prescribed. This is an acne medicine that is taken orally to help over-active oil glands. This acne medicine has some dangerous side-effects such as liver damage and birth defects. Although it can be effective in the short run it is usually reserved as a last resort.

Retin-A creams are formed from a derivative of Vitamin A and is a prescription acne medicine. This form of Vitamin A helps to take off the top layer of dead cells which often block the pores in the skin.

Phototherapy is still experimentally being used to help clear acne. Although not a specific medication, because it is regulated for use by the FDA it can be considered an acne medicine. Phototherapy is the special use of light bulbs that give off a blue or red and blue light. This particular treatment has been found to work as well or better than benzoyl peroxide, a common ingredient in over the counter and prescription medication.

There are no universal treatments for acne. The resolution of the condition is gradual and can extend over a period of time. There just are no quick fixes and there are no instant cures. Acne medicines take time, patience, and persistence.
