A whitehead on the lower eyelid should not be popped as the bacteria, pus or fluid resulting can infect the skin and the eye, according to WebMD. In most cases, the whitehead pimple may be an abscess known as a stye.
When a whitehead is popped, the bacteria within the pimple can splatter and spread to other pores, which may cause more pimples, according to WebMD. Bacteria from the hands may also force bacteria deeper into the skin, cause the eyelid to become swollen, infected, red or inflamed and may lead to scarring on the eyelid or face. Pimples typically heal naturally within seven days.
Most commonly, bumps on the eyelid are styes, which are forms of pimples, according to WebMD. Styes form as a result of a blockage of bacteria and oil ducts on the eyelid. Many styes heal on their own, but if the infection causes pain, the fluid-filled cyst may need to be opened and drain by a trained physician.
To minimize the white appearance or discomfort from a stye, patients can apply hot compresses three or four times a day for 10 to 15 minutes, according to All About Vision. In many cases, styes rupture, drain and heal on their own.
