## **What Causes Bumpy Skin?**

## Keratosis Pilaris (KP)

One of the most common causes of bumpy skin is keratosis pilaris, which typically appears as small, rough bumps on the arms, thighs, and back. KP occurs when excess keratin blocks hair follicles, leading to the formation of bumps.

## Body Acne and Back Acne

Back acne or bacne is another frequent cause of bumps, particularly on the back, shoulders, and chest. This condition is a result of clogged pores and follicles, often due to excess oil production, sweat, or hormonal fluctuations.

## Dry Skin and Dead Skin Cells

When the skin's surface becomes dry or there's a build-up of dead skin cells, rough patches can develop.
