Your skin has tiny holes called pores that that can become blocked by oil, bacteria, and dirt. When this occurs, you may develop a pimple or “zit.” If your skin is repeatedly affected by this condition, you may have acne. According to the American Academy of Dermatology (AAD), acne is one of the most common skin problems in the United States. At any one time, between 40 and 50 million people have this condition. Although acne is not a life-threatening condition, it can be painful, particularly when it is severe. It can also cause emotional distress. Acne that appears on the face can impact self-esteem and, over time, may cause permanent scarring. Fortunately, there are effective treatments for this condition that reduce both the number of pimples you get and the chance for scarring to occur.
Acne occurs when the pores on your skin become blocked with oil, dead skin, or bacteria. Each pore on your skin is the opening to a follicle. The follicle is made up of a hair and a sebaceous (oil) gland. The oil gland releases sebum (oil), which travels up the hair, out of the pore, and onto your skin. The sebum keeps your skin lubricated and soft. If you develop acne, this may be because of one or more problems in this lubrication process. These possible causes include:
An overabundance of oil, a pore clogged by dead skin cells, and bacteria all contribute to the development of pimples. A zit appears when the bacteria grows in the clogged pore and the oil is unable to escape.
Myths about what contributes to acne are quite common. Many people believe that foods such as chocolate or French fries will contribute to the development of acne. While there is no scientific support for these claims, there are certain risk factors that may put you at risk for developing acne. These include:
Young people are most at risk for developing acne during puberty. During this time, the body undergoes drastic hormonal changes. These hormones can trigger oil production, leading to an increased risk of acne. Hormonal acne related to puberty usually subsides when a teenager reaches adulthood.
Acne can be found anywhere on your body. It most commonly develops on the face, back, neck, chest, and shoulders. If you have acne, you will typically notice pimples that are white or black in appearance. Both blackheads and whiteheads are known as comedones. Blackheads open at the surface of the skin giving them a black appearance. Whiteheads are closed just under the surface of the skin, giving them a white appearance. While whiteheads and blackheads are the most common types of acne, other lesions can occur. Inflammatory lesions are more likely to cause scarring of the skin and include the following:
If you have symptoms of acne, your doctor will be able to confirm a diagnosis by examining your skin.
You can use a number of self-care activities at home to prevent pimples and to clear up your acne. Home remedies for acne may include:
If self-care activities do not help with your acne, there are a number of over-the- counter acne medications that may be helpful. Most of these medications contain ingredients that can help kill bacteria or dry the skin. These active ingredients include:
Sometimes, you may continue to experience symptoms. If this happens, you may want to seek medical advice. Your doctor can prescribe medications that may help reduce your symptoms and prevent scarring. Your doctor may give you oral or topical antibiotics. These kill the bacteria that cause pimples. Typically, antibiotics are only used for a short amount of time so that your body doesn’t build up a resistance. Antibiotic resistance can make you prone to infections. Topical creams like retinoic acid or prescription strength benzoyl peroxide are often stronger formulas of over-the-counter treatments. These work to dry out the skin and reduce oil production. Women with hormonal acne may be treated with birth control pills or spironolactone. These medications seek to regulate the hormone-causing acne. Isotretinoin (Accutane) is a vitamin A-based medication that is used to treat certain cases of severe nodular acne. It has serious side effects, and is only used when all other treatments have failed.
Your doctor may recommend additional procedures to treat severe acne and prevent scarring. Many of these work by removing damaged skin.
Your doctor may suggest using cortisone injections if your acne consists of large cysts. Cortisone is a steroid naturally produced by the body. It can reduce inflammation and speed healing.
Treatment for acne is often successful. Most people can expect their acne to clear up within six to eight weeks. However, flare-ups of the condition are common and may require additional treatment. Scarring that occurs as a result of acne can cause emotional distress. Prompt treatment can help prevent scarring.
It’s difficult to prevent acne. However, you can take some steps at home to help prevent acne following treatment. These include:
