Keratosis Pilaris (KP) is a common skin condition that causes small, rough bumps to appear on the skin, most commonly on the upper arms, thighs, and cheeks. These bumps are caused by an overproduction of keratin, a protein that makes up the top layer of the skin. While KP is not harmful, it can be unsightly and cause itching and irritation.

Symptoms of KP include small, rough bumps on the skin, dry and scaly patches, and redness or inflammation. In some cases, the bumps may be itchy or painful. KP is more common in people with dry skin, eczema, and other skin conditions.

Diagnosis of KP is typically made through a physical examination of the affected skin. A dermatologist may also perform a skin scraping to look for signs of inflammation or infection.

Treatment options for KP include moisturizing the skin, using exfoliating scrubs or acids to remove the buildup of dead skin cells, and using topical creams or ointments containing retinoids or alpha hydroxy acids. In some cases, laser therapy or light therapy may be used to improve the appearance of the skin.

Preventing KP from occurring is difficult as the exact cause is unknown. However, keeping the skin well-moisturized, avoiding harsh soaps and detergents, and avoiding excessive sun exposure can help to reduce the risk of developing KP.
