There are many causes of eyelid fatty grains, including congenital and acquired factors, as follows: 1. congenital factors: some people have small yellow particles around their eyelids after birth, caused by genetics. 2. acquired factors: for example, long-term sun exposure, use of substandard and poor quality cosmetics, or violent rubbing of the skin, secondary infection, can cause eyelid fatty grains. For the treatment of fatty grains, you can usually choose an antibiotic eye ointment with a combination of hormonal eye ointments. For acquired cases, such as those caused by sun exposure, it is important to avoid exposing the eyelid skin to the sun and to avoid using poor quality cosmetics. The fatty pellets will gradually fade with medication, but if they do not fade with medication, skin freezing or laser treatment can be considered.
