    GlossaryFollicular Hyperkeratosis (Phrynoderma)

    condition where hair follicles clog with keratin, causing bumps

    Follicular Hyperkeratosis, also known as Keratosis Pilaris, is a common skin condition where hair follicles become clogged with keratin, a protein found in the skin. This results in small, rough bumps, often on the arms, thighs, cheeks, or buttocks, giving the skin a sandpaper-like texture. It is generally harmless but can be cosmetically concerning for some individuals.
