The tiny white bumps on your eyelids are most commonly known as milia. Milia are small, keratin-filled cysts that form just under the surface of the skin. They are typically 1 to 2 millimeters in size and have a pearly-white appearance. Unlike acne, milia are not caused by clogged pores or bacterial infections.
Milia can occur at any age and are particularly common in newborns. However, they can also develop in adults, especially around the eye area where the skin is delicate and thin. They are usually harmless and not associated with any underlying medical condition.
2. Milia 101: Why These Little Cysts Form Around the Eyes
Milia form when dead skin cells become trapped in small pockets near the skin’s surface instead of exfoliating naturally. This trapped keratin becomes a tiny cyst. The formation of milia is not fully understood, but it is believed to be related to skin damage, such as from sun exposure, or the use of heavy skincare products that can clog the skin’s surface.
The eye area is particularly prone to milia because the skin is thinner and more sensitive to environmental damage and product buildup. People who use thick creams or heavy makeup around the eyes without proper cleansing may be more susceptible to developing milia.
3. How to Tell Milia From a Stye, Chalazion, or Whitehead
Distinguishing milia from other eyelid conditions is essential for proper management. Milia are firm, white, and painless bumps that do not change much in size. A stye, on the other hand, is a red, painful lump near the edge of the eyelid, caused by an infection of an oil gland. Styes are often tender to the touch and can cause swelling of the eyelid.
A chalazion is similar to a stye but is usually larger, less painful, and occurs further back on the eyelid. Chalazia result from a blocked oil gland and can take longer to resolve. Whiteheads, unlike milia, are soft, filled with pus, and often part of acne breakouts.
