What is keratosis pilaris?

Keratosis pilaris is characterized by the presence of small, rough bumps on the skin, often described as "chicken skin." This condition is caused by the accumulation of keratin, a protein in the skin, which leads to the blockage of hair follicles. As a result, the skin appears bumpy and may exhibit redness, particularly on areas like the cheeks, arms, and thighs. It is not associated with active acne or flaking skin but instead highlights the clogging of follicles due to the excess keratin. Understanding this mechanism is essential for distinguishing keratosis pilaris from other skin conditions that present with similar symptoms.
