What to know about pimples on arms

Many things, including infections and blocked pores, can cause a person to develop pimples on the arms. Because the fabric of clothing generally covers this part of the body, sweat or dirt can collect and clog pores.

Simple remedies and prevention tips can treat these pimples in many cases.
A pimple is an inflamed red spot that is often filled with pus. Pimples or zits can develop anywhere on the body. Causes include the body producing too much oil, a clogged pore, or a medical condition. The condition of keratosis pilaris often affects the skin on the arms, for example.

Pimples can look different depending on the person or the cause. They can appear as red, swollen, small, black-headed or white bumps due to pus.


Acne is a very common skin condition. Characterized by pimples that can vary in appearance from red to black, acne can affect any part of the body. It is most common on the face, back, shoulders, and upper arms. Acne can affect people of any age, race, and gender. A common trigger for acne is hormonal changes, which is why it commonly affects young adults.

Acne causes the body to produce too much oil or sebum, which mixes with dead skin cells to block pores. Bacteria on the skin infect these blocked pores, which cause pimples.

Keratosis pilaris

Keratosis pilaris is a skin condition that causes small rough bumps to develop on the skin. The bumps are most common on the upper arms and on the front of the thighs. Dead skin blocks pores and causes bumps. Keratosis pilaris may be itchy, but it is harmless.


Hives can appear as small red, itchy spots anywhere on the skin. Sometimes they are the result of an allergic reaction. An insect bite can also cause them to develop. A reaction to a skin irritant, heat, or stress usually causes the rash.
Staph infection

A staph infection can cause red pimples or a rash, although it can also look like sores or blisters. Staph bacteria live on parts of the skin, such as the armpits and nose. If these bacteria get into a cut, it can cause a staph infection.

It is important to treat staph promptly, as it can sometimes cause complications. If the infection reaches the body’s organs, it can be fatal. A person should see a doctor if they suspect that he has a staph infection.


Folliculitis affects the hair follicles and can appear anywhere there are follicles on the body. When hair follicles are damaged, bacteria can enter and cause an infection. This usually appears as red spots on the skin. The symptoms of folliculitis can resemble acne.

Shaving, rubbing the skin, and wearing tight clothing can damage hair follicles. This is most likely to occur when the skin is hot and moist.


Skin infections that cause pimples often go away without treatment. Applying a warm washcloth to the skin can help relieve folliculitis symptoms. Sometimes a staph infection requires treatment with antibiotics. This is likely to be the case if a person has a rash that lasts longer than a week, gets worse, or spreads quickly.

Acne may require drug treatment. Topical treatments include creams and lotions that a person applies to the skin. These kill bacteria or reduce the amount of oil your skin produces and can take 4 to 8 weeks to work. Continuing treatment after this can help prevent acne from recurring.

Laser therapy, light therapy, and chemical peels are other options for treating acne. These can help eliminate bacteria from the skin or remove the top layer of the skin to clean the pores.

Treating dry skin can help eliminate keratosis pilaris or decrease the appearance of pimples. Applying a moisturizer two to three times a day can prevent your skin from drying out. Gently massage into skin after showering or bathing for best results.
