What are those scaly bumps on your arms and thighs, and how can you treat them?

Keratosis pilaris (KP) is a common, harmless skin condition characterized by small, rough bumps on the skin’s surface. These bumps typically appear on the upper arms, thighs, buttocks, and occasionally seen on the face as well. As dermatologists, this is a common skin finding we see often in clinic.

The bumps associated with KP are often described as small, rough, and skin-colored or slightly red. They can resemble goosebumps or the texture of sandpaper, and also have been referred to as chicken skin: KP most commonly affects the outer sides of the upper arms (particularly triceps area), thighs, and buttocks. It can also occur on the cheeks. This condition is caused by extra build up of keratin/dry skin around the hair follicles, trapping the hair follicles themselves, and causing that roughness/bumpiness you may feel. Luckily this condition is asymptomatic typically, however sometimes can result in dry or itchy skin depending on the climate.

Treatment is centered around exfoliation to get rid of the excess keratin. As always I prefer chemical to physical exfoliation. Keeping the skin hydrated is the key! Using an alpha hydroxy acid based product or a retinoid can be helpful in helping gently remove that excess keratin. Oathology’s TBH serum contains THREE alpha hydroxy acids: glycolic, lactic, and mandelic acid and can help you achieve less bumpy skin. If your skin can tolerate stronger chemical exfoliants, one can also use Oathology’s Retinoath serum which is a granactive retinoid that offers the power of a Vitamin A based treatment without a prescription.

Keep in mind one should also moisturize often if using either of these treatments. Keeping the skin well moisturized is essential. Use gentle, fragrance-free moisturizers regularly, especially after bathing.

Other ingredients that can be helpful include urea, salicylic acid, or retinoids to help unclog pores and reduce the appearance of bumps.

Don’t forget about sun protection when using any exfoliant. AHAs can increase your skin’s sensitivity to the sun, so it’s crucial to apply sunscreen daily, even if you’re indoors. Choose a broad-spectrum sunscreen with SPF 30 or higher. We recommend pairing our Oathology TBH Serum with our sold out 6x viral Oathology Inzincable sunscreen.

Speak with your dermatologist if KP is bothersome or persistent, a dermatologist can provide guidance on the best treatment options tailored to your specific skin type and condition.

While keratosis pilaris is typically a harmless condition, it can be persistent and bothersome for some individuals. With proper care and treatment, most people can manage the appearance and symptoms effectively.
