Keratosis pilaris (KP) is a very common genetic follicular condition that is manifested by the appearance of rough bumps on the skin and hence colloquially referred to as "chicken skin". It most often appears on the back and outer sides of the upper arms (though the lower arms can also be affected), and can also occur on the thighs and tops of legs, flanks, buttocks or any body part except glabrous skin (like the palms or soles of feet). Less commonly, lesions appear on the face and may be mistaken for acne.
Worldwide, KP affects an estimated 40 to 50% of the adult population and approximately 50 to 80% of all adolescents. It is more common in women than in men. Varying in degree, cases of KP can range from minimal to severe.[citation needed]
There are several different types of keratosis pilaris, including keratosis pilaris rubra (red, inflamed bumps), alba (rough, bumpy skin with no irritation), rubra faceii (reddish rash on the cheeks) and related disorders.
Many people with keratosis pilaris do not know they have it (if the condition is mild). While KP resembles goose bumps, it is characterized by the appearance of small rough bumps on the skin. As a result, it is often confused with acne.
Keratosis pilaris occurs as excess keratin, a natural protein in the skin, accumulates within the hair follicles forming hard plugs (process known as hyperkeratinization). Bearing only cosmetic consequence, the condition most often appears as a proliferation of tiny hard bumps that are seldom sore or itchy. Though people with keratosis pilaris experience this condition year round, it’s during the colder months when moisture levels in the air are lower that the problem can become exacerbated and the “goose bumps” are apt to look and feel more pronounced in color and texture.
There has be no actor or actresses that have admitted to have this disease and it is not surprising as it may jeopardise them getting a job especially on television and film work.
