Explanation:
Detailed explanation-1: -Keratosis pilaris may make your skin look like you have “goose bumps.” The bumps are often the color of your skin. They may also look white, red, pinkish-purple on fair skin, or brownish-black on dark skin. They can feel rough and dry like sandpaper. They may itch, but they don’t hurt.
Detailed explanation-2: -Goose bumps are created when tiny muscles at the base of each hair, known as arrector pili muscles, contract and pull the hair straight up. The reflex is started by the sympathetic nervous system, which is responsible for many fight-or-flight responses.
