What skin condition is typically associated with a buildup of keratin in hair follicles?

The skin condition characterized by a buildup of keratin in hair follicles is known as keratosis pilaris. This condition leads to small, rough bumps on the skin, often resembling goosebumps. The excess keratin forms hard plugs within the hair follicles, resulting in these distinctive elevations. Keratosis pilaris commonly appears on the upper arms, thighs, face, and buttocks, and while it is usually harmless and often asymptomatic, it can cause a cosmetic concern for some individuals.

Understanding the nature of keratosis pilaris highlights the importance of managing keratin production effectively to prevent its buildup. This condition is often treated with moisturizers and exfoliants that can help remove the dead skin cells and smooth the affected areas.

In contrast, acne vulgaris is associated with a buildup of oil and bacteria in a blocked pore rather than keratin specifically. Psoriasis is an autoimmune condition that speeds up the life cycle of skin cells, leading to red, scaly patches, and dermatitis encompasses a group of conditions that cause inflammation of the skin but does not specifically involve keratin buildup in hair follicles.
