Small, white bumps that are present on the skin may be keratosis pilaris, otherwise known as keratin spots, which is caused by keratin accumulating underneath the skin, as reported by WebMD. Keratosis pilaris is a harmless skin condition, and the bumps can appear basically anywhere on the body like on the thighs, facial regions, buttocks and arms. The buildup of the keratin ends up clogging the skin pores and causes a bump to form.
Keratin is a natural compound made by the body to fend off infections and other harmful things. At this moment, medical professionals have not yet determined the underlying cause behind this condition although studies have shown that those with dry skin are more prone to it. Keratosis pilaris is also more prevalent with individuals with pre-existing skin conditions, like eczema.
To prevent keratosis pilaris, keep the skin moisturized at all times and use soaps that have added oils and fats in them. Using warm water instead of hot water when bathing also seems to be effective.
There are no cures available on the market just yet; however, those who are struggling with keratosis pilaris can opt for laser surgery or topical exfoliators that may help get rid of the skin buildup so that the keratin can be extracted.
