small, rough skin bumps from keratin buildup in hair follicles
Keratotic Follicular Papules are small, rough bumps on the skin caused by the buildup of keratin, a protein that protects skin from infections and other harmful things. These bumps often appear on the upper arms, thighs, or cheeks and are commonly associated with conditions like keratosis pilaris. For professionals, they indicate hyperkeratinization at the hair follicle, leading to follicular plugging and inflammation.
