Answer

Overall, keratosis pilaris is described as a condition of childhood and adolescence. Although it often becomes more exaggerated at puberty, it frequently improves with age. However, many adults have keratosis pilaris late into senescence. Approximately 30-50% of patients have a positive family history. Autosomal dominant inheritance with variable penetrance has been described. The autosomal recessive form of keratosis pilaris atrophicans is related to a desmoglein 4 mutation. [2]
