A milium (single for milia) is a small superficial cyst formed in the top layer of the skin called the epidermis. Milia appear as tiny, pearly-white bumps just under the surface of the skin and contain keratin (skin protein). They are often seen on the face, in particular on the delicate skin around the eyes. While milia are harmless, they can be prevented or minimized with exfoliation techniques like chemical peels, microdermabrasion or topical retinoids. However, they are sometimes difficult to remove without a physician’s help, since they cannot simply be squeezed out. Often, the surface of the skin has to be pierced first with a lancet, a sharp pointed blade, or a needle, in order to open the milium, which can then be removed with a comedone extractor.
