Acne: Types, Causes, Treatment & Prevention

How is acne treated?

There are several ways to treat acne. Each type of treatment varies based on your age, the type of acne you have and the severity. A healthcare provider might recommend taking oral medications, using topical medications or using medicated therapies to treat your skin. The goal of acne treatment is to stop new pimples from forming and to heal the existing blemishes on your skin.

Topical acne medications

Your healthcare provider may recommend using a topical acne medication to treat your skin. You can rub these medications directly onto your skin as you would a lotion or a moisturizer. These could include products that contain one of the following ingredients:

Benzoyl peroxide: This is available as an over-the-counter product (such as Clearasil®, Stridex® and PanOxyl®) as a leave-on gel or wash. It targets surface bacteria, which often aggravates acne. Lower concentrations and wash formulations are less irritating to your skin.Salicylic acid: This is available over the counter for acne as a cleanser or lotion. It helps remove the top layer of damaged skin. Salicylic acid dissolves dead skin cells to prevent your hair follicles from clogging.Azelaic acid: This is a natural acid found in various grains such as barley, wheat and rye. It kills microorganisms on the skin and reduces swelling.Retinoids (vitamin A derivatives): Retinol, such as Retin-A®, Tazorac® and Differin®, which is available without a prescription, breaks up blackheads and whiteheads and helps prevent clogged pores, the first signs of acne. Most people are candidates for retinoid therapy. These medications aren’t spot treatments and must be used on the entire area of skin affected by acne to prevent the formation of new pimples. You often need to use these for several months before noticing positive results.Antibiotics: Topical antibiotics like clindamycin and erythromycin control surface bacteria that aggravate and cause acne. Antibiotics are more effective when combined with benzoyl peroxide.Dapsone: Dapsone (Aczone®) is a topical gel, which also has antibacterial properties. It treats inflamed acne.Oral acne medications

Oral acne medications are pills that you take by mouth to clear your acne. Types of oral acne medications could include:

Antibiotics: Antibiotics treat acne caused by bacteria. Common antibiotics for acne include tetracycline, minocycline and doxycycline. These are best for moderate to severe acne.Isotretinoin (Amnesteem®, Claravis® and Sotret®): Isotretinoin is an oral retinoid. Isotretinoin shrinks the size of oil glands, which contributes to acne formation.Contraceptives: The use of certain contraceptives can sometimes help women who have acne. The U.S. Food and Drug Administration (FDA) approved several types of birth control pills for treating acne. Some brand names include Estrostep®, Beyaz®, Ortho Tri-Cyclen® and Yaz®. These pills contain a combination of estrogen and progesterone.Hormone therapy: Hormone therapy is helpful for some people with acne, especially those who experience acne flare-ups during menstruation or who have irregular periods caused by excess androgen. Hormone therapy may be in the form of low-dose estrogen and progesterone pills (birth control pills), or a medication called spironolactone that blocks the effect of certain hormones at the level of your hair follicles and oil glands.Additional acne therapies

If topical or oral medications don’t work well for your acne, or if you have acne scars, a healthcare provider may recommend different types of therapies to clear your skin, including:

Steroids: Steroids can treat severe acne with injections into large nodules to reduce inflammation.Lasers: Lasers and light therapy treat acne scars. A laser delivers heat to the scarred collagen under your skin. This relies on your body’s wound-healing response to create new, healthy collagen, which encourages growth of new skin to replace it.Chemical peels: This treatment uses special chemicals to remove the top layer of old skin. After removal of the top layer of skin, new skin grows in smoother and can lessen acne scars.

How do antibiotics treat acne?

Antibiotics are medications that target bacteria. Bacteria can clog your pores and cause acne. Some antibiotics that treat acne also can decrease inflammation. Antibiotics are responsible for:

Blocking bacteria from entering your body.Destroying bacteria.Preventing bacteria from multiplying.

A healthcare provider will recommend antibiotics if you have acne caused by bacteria or if you have an infection. Antibiotics get rid of an infection if bacteria gets into a popped pimple, which can swell and become painful. This medication isn’t a cure for acne, and you shouldn’t take it long-term to treat acne.

How can I make my acne go away at home?

If you have acne, you can start an at-home skin care routine to help your acne go away by:

Wash your skin at least once daily with warm (not hot) water and a gentle cleanser. Cleansers are over-the-counter skin care products that help clean your skin.Wash your skin after you exercise or sweat.Avoid using skin care products with alcohol, astringents, toners and exfoliants, which can irritate your skin.Remove makeup at the end of the day or before you go to bed.Choose an oil-free moisturizer to apply on your skin after cleansing.Avoid popping, picking or squeezing your acne. Let your skin heal naturally to prevent scars from forming on your skin.

If your at-home skin care routine isn’t effective at treating acne, visit a healthcare provider.

Is acne treatment safe when you're pregnant?

Many topical and oral acne treatments aren’t safe to take during pregnancy. If you’re pregnant or planning on becoming pregnant, it’s important to discuss acne treatments with your healthcare provider and notify them if you become pregnant.

How long does it take for acne to go away?

On average, it can take between one to two weeks for acne pimples to clear up on their own. With medicated treatment and a good skin care routine, you can speed up your body’s healing time to make acne go away faster. For severe acne, it can take several weeks for your acne to go away, even with treatment.
