Keratosis Pilaris is a common skin condition characterized by small, rough bumps, often resembling goosebumps. These bumps typically appear on the upper arms, thighs, cheeks, and buttocks. The condition occurs when keratin, a protein in the skin, builds up and clogs hair follicles, leading to the formation of these tiny, raised spots. While keratosis pilaris is harmless and not contagious, it can be more noticeable in individuals with dry skin. The condition often improves with age and can be managed with moisturizers and gentle exfoliation. It is important to consult a dermatologist for personalized treatment options if desired.
