What disorder is characterized by blocked hair follicles causing redness and bumpiness?

The disorder characterized by blocked hair follicles, leading to redness and bumpiness, is indeed keratosis pilaris. This condition is a common skin issue that results from the buildup of keratin, a protein found in the skin. When keratin clogs the hair follicles, it can cause small, rough, red bumps to appear, typically on the upper arms, thighs, cheeks, and buttocks.

Unlike acne, which involves inflamed or infected pores and can include pus-filled bumps, keratosis pilaris is not typically inflamed and is more about texture than specific breakouts. Eczema, on the other hand, is an inflammatory skin condition that usually presents as itchy, inflamed patches rather than bumps resulting from follicle blockage. Psoriasis is a chronic autoimmune condition that leads to thick, red, scaly patches and is distinct from the characteristics of keratosis pilaris. Thus, keratosis pilaris is accurately described by the symptoms of blocked hair follicles causing redness and bumpiness.
