milia also known as whiteheads are very common white pimples that can occur in persons of all ages. they appear mostly on the upper cheeks nose and chin of infants. this occurs when dead skin cells and sebaceous matter gets trapped near the skin surface rather than exfoliating naturally. common causes of milia include the use of thick and heavy cosmetics or poor-quality products that are not suitable for the skin that prevent the sloughing-off of dead skin cells. excessive sun exposure makes the skin thick which leaves it unable to exfoliate naturally.
what causes milia? how can i avoid getting these?
