Blackheads: Causes, Symptoms, and Treatments

Blackheads are small bumps that appear on your skin due to clogged hair follicles. These bumps are called blackheads because the surface looks dark or black. Blackheads can usually be treated with over-the-counter acne products.

Blackheads are a mild type of acne that usually form on the face, but they can also appear on the following body parts:

back
chest
neck
arms
shoulders

Acne affects nearly 50 million Americans and is the most common skin disorder in the United States, according to the American Academy of Dermatology.

What do blackheads look like?

What causes blackheads?

Blackheads form when a clog or plug develops in the opening of hair follicles in your skin. Each follicle contains one hair and a sebaceous gland that produces oil. This oil, called sebum, helps keep your skin soft.

Dead skin cells and oils collect in the opening to the skin follicle, producing a bump called a comedo. If the skin over the bump stays closed, the bump is called a whitehead. When the skin over the bump opens, exposure to the air causes it to look black and a blackhead forms.

Some factors can increase your chances of developing acne and blackheads, including:

producing too much body oil
the buildup of the Propionibacterium acnes bacteria on the skin
irritation of the hair follicles when dead skins cells don’t shed on a regular basis
undergoing hormonal changes that cause an increase in oil production during the teen years, during menstruation, or while taking birth control pills
taking certain drugs, such as corticosteroids, lithium, or androgens

Some people believe that what you eat or drink can affect acne. Dairy products and foods that increase blood sugar levels, such as carbohydrates, may play a part in triggering acne, but researchers aren’t convinced that there’s a strong connection.

What are symptoms of blackheads?

Because of their dark color, blackheads are easy to spot on the skin. They’re slightly raised, although they aren’t painful because they aren’t inflamed like pimples. Pimples form when bacteria invade the blockage in the hair follicle, causing redness and inflammation.

How are blackheads treated?

Over-the-counter (OTC) treatments

Many acne medications are available at drug and grocery stores and online without a prescription. These medications are available in cream, gel, and pad form and are put directly on your skin. The drugs contain ingredients such as salicylic acid, benzoyl peroxide, and resorcinol. They work by killing bacteria, drying excess oil, and forcing the skin to shed dead skin cells.

Prescription medications

If OTC treatment doesn’t improve your acne, your doctor may suggest that you use stronger prescription medications. Medications that contain vitamin A keep plugs from forming in the hair follicles and promote more rapid turnover of skin cells. These medications are applied directly to your skin and can include tretinoin, tazarotene, or adapalene.

Your doctor may also prescribe another type of topical medication that contains benzoyl peroxide and antibiotics. If you have pimples or acne cysts in addition to your blackheads, this type of medication may be particularly helpful.

Manual removal

Dermatologists or specially trained skin care professionals use a special instrument called a round loop extractor to remove the plug causing the blackhead. After a small opening is made in the plug, the doctor applies pressure with the extractor to remove the clog.

The Healthline FindCare tool can provide options in your area if you don’t already have a dermatologist.

Microdermabrasion

During microdermabrasion, a doctor or skin care professional uses a special instrument that contains a rough surface to sand the top layers of your skin. Sanding the skin removes clogs that cause blackheads.

Chemical peels

Chemical peels also remove clogs and get rid of the dead skins cells that contribute to blackheads. During a peel, a strong chemical solution is applied to the skin. Over time, the top layers of the skin peel off, revealing smoother skin underneath. Mild peels are available over the counter, while stronger peels are performed by dermatologists or other skincare professionals.

Laser and light therapy

Laser and light therapies use tiny beams of intense light to decrease oil production or kill bacteria. Both lasers and light beams reach below the surface of the skin to treat blackheads and acne without damaging the top layers of the skin.

How can blackheads be prevented?

You can prevent blackheads without spending a lot of money by trying a few of the following ideas:

Wash regularly

Wash your face when you wake up and before you go to bed to remove oil buildup. Washing more than twice each day can irritate your skin and make your acne worse. Use a gentle cleanser that doesn’t make your skin red or irritated. Some acne cleansing products have antibacterial ingredients that kill P. acnes bacteria.

Consider washing your hair every day, too, particularly if it’s oily. Hair oils can contribute to clogged pores. It’s also important to wash your face after you eat oily foods such as pizza, because oil from these foods can clog pores.

Use oil-free products

Any product that contains oil can contribute to new blackheads. Choose oil-free or noncomedogenic makeup, lotions, and sunscreens to avoid making your problem worse.
