Keratosis Pilaris (KP) is a common problem that results in rough texture at the back of the upper arms, thighs, buttocks, back and sometimes cheeks. It’s so common that almost every day at least one patient tells me they have “goose bumps” or “chicken skin” that they would like help treating. 40% of adults, and up to 80% of adolescents experience this. KP looks like rough, slightly red or skin colored bumps. While KP is harmless and generally doesn’t itch or hurt, it can be quite annoying. It occurs when excess keratin, one of the major proteins in the skin, forms hard plugs within hair follicles. This plug then traps the hair in the follicle. KP runs in families and happens more when people have a tendency for dry skin or eczema. Sometimes it just happens. Because it’s associated with dryness, KP is usually worse in the winter or in dry climates, and improves in warm and humid climates.
