Keratosis pilaris, colloquially known as "chicken skin," affects an estimated 50% to 80% of teenagers and 40% of adults, according to recent figures. While a single, direct cause remains elusive, many people ask what deficiency causes KP, believing a simple nutritional fix exists. In reality, the condition is primarily rooted in a genetic predisposition to keratin overproduction, though nutritional status can influence its severity.

Affecting up to 80% of adolescents and 40% of adults, the rough, tiny bumps on the backs of your arms are most likely a common and harmless skin condition called keratosis pilaris (KP). While the condition has a strong genetic link, KP symptoms can be worsened by nutritional factors, leading many to wonder what vitamin are you lacking when you have bumps on your arms.
