What are Arm Pimples?
Arm pimples can appear as whiteheads or pus-filled bumps on the arms that happen when hair follicles get clogged with oil, bacteria, and dead skin cells.
But arm pimples aren’t always acne. Small, rough bumps on the upper arms can be keratosis pilaris (KP), caused by keratin protein buildup in the hair follicles. Red, inflamed pimples on the arms can be folliculitis, a skin condition caused by bacterial or fungal infections.
You may also see these pimples on your legs and other areas of the body like chest and back.
What Causes Arm Acne?
Arm acne typically occurs when the pores or hair follicles get clogged with dead cells, excess sebum, and bacteria. The most common causes include sweat, pore-clogging skincare products, friction from tight clothing, and hormonal fluctuations.
However, not all arm pimples are actually acne. Keratosis pilaris appears as small, rough bumps caused by keratin buildup. Folliculitis, on the other hand, appears as red, sometimes itchy bumps on the skin caused by heat, sweat, and shaving.
How to Prevent Arm Breakouts
The best way to prevent arm pimples is by keeping pores clear and reducing friction. You can do this by showering straight after working out or heavy sweating so that oils don’t trap bacteria in your hair follicles.
To prevent build up in your pores, apply a leave on exfoliating product 2-3 times a week. And moisturize daily with a lightweight, non-comedogenic moisturizer as dry skin produces more oil to compensate.
To prevent friction-induced arm pimples, wear loose, breathable clothing that doesn’t rub against your skin.
Now you know how to get rid of arm pimples easily, make sure you stock up on our recommended products to keep your arms clear and silky smooth.
Many people will find that the above options are effective for clearing arm breakouts. However, if you still experience these bumps after using these products consistently for six weeks, consult your dermatologist for advice.
