Sometimes referred to as “chicken skin,” keratosis pilaris looks like tiny, often red, white, or flesh-colored bumps on the skin. It’s totally harmless and caused by a buildup of keratin around the hair follicle, which can clog pores and cause inflammation or redness in the area. These red bumps on the legs and the backs of arms occur when sticky cells within the hair follicle clump together to form a plug, preventing them from being whisked away through routine exfoliation. This common condition, believed to be genetic, can be minimized but not cured with lactic acid creams or scrubs.
