Those small white bumps under your eyes are most likely milia, tiny cysts filled with a protein called keratin that gets trapped just beneath the skin’s surface. They’re extremely common, completely harmless, and not a sign of poor hygiene. That said, not every bump under the eye is the same thing. A few other conditions look similar enough to cause confusion, and telling them apart matters because the right approach depends on what you’re actually dealing with.
Milia: The Most Common Cause
Milia are small, dome-shaped cysts that typically measure 1 to 2 millimeters across. They’re white or yellowish-white, feel firm to the touch, and don’t pop like a pimple no matter how much you’re tempted to try. Unlike acne, milia aren’t inflamed or painful. They just sit there, looking like tiny pearls embedded in the skin.
They form when dead skin cells get trapped in a small pocket near the surface instead of shedding naturally. Research suggests this happens through a blockage in the tiny channels surrounding fine facial hairs. The trapped cells produce keratin, the same structural protein that makes up your hair and nails, and that keratin fills the pocket into a firm little ball. The under-eye area is especially prone because the skin there is thinner than almost anywhere else on your body, making these small deposits more visible.
In babies, milia are so common they’re considered normal and typically clear up on their own within a few weeks to months. Adults can also see milia resolve without treatment, though they tend to be more persistent. Heavy eye creams, thick sunscreens, and oil-based products can contribute to their formation by creating a barrier that traps dead skin cells. Sun damage also plays a role, since it thickens the outer layer of skin and makes it harder for cells to shed properly.
Other Bumps That Look Similar
Syringomas
Syringomas are small, firm bumps caused by an overgrowth of cells in your sweat glands. They appear in clusters, are typically 1 to 3 millimeters in diameter, and tend to be yellow, translucent, or skin-colored rather than the pearly white of milia. They show up most often on the lower eyelids and cheeks. The key difference is that syringomas are deeper in the skin and won’t resolve on their own. Under a microscope, they have a distinctive tadpole or comma shape. They’re benign and don’t require treatment unless they bother you cosmetically.
Xanthelasma
Xanthelasma looks different from milia once you know what to look for. These are flat or slightly raised yellowish patches, not round bumps, that appear on or near the eyelids. They’re deposits of fat beneath the skin. There’s a common assumption that xanthelasma signals high cholesterol, but a study from the American Academy of Ophthalmology found that people with these patches had essentially the same rate of lipid disorders (42%) as people without them (46%). Still, if you develop yellowish plaques near your eyes, getting your cholesterol checked is reasonable since the connection exists in some cases even if it’s not as strong as once believed.
Sebaceous Hyperplasia
These bumps are caused by enlarged oil glands. They tend to be skin-colored or slightly yellowish with a small central indentation, almost like a tiny donut. They’re more common in middle-aged and older adults and can appear anywhere on the face, including near the eyes. A dermatologist can usually identify them with a visual exam, sometimes using a magnifying instrument called a dermoscope. In rare cases, a biopsy is recommended because sebaceous hyperplasia can resemble a type of skin cancer called basal cell carcinoma.
How to Tell What You Have
Color and texture are your best clues. Milia are distinctly white and round, like a grain of sand under the skin. Syringomas cluster together and lean more yellow or translucent. Xanthelasma forms flat, irregular patches rather than round bumps. Sebaceous hyperplasia has that characteristic dimple in the center.
If a bump is growing, changing color, bleeding, or developing an irregular border, those features point away from all of the harmless conditions above. Any bump near the eye that looks different from the others, changes over weeks, or develops a pearly, waxy quality should be evaluated by a dermatologist to rule out skin cancer.
Getting Rid of Milia
You have two basic paths: letting them resolve naturally or having them removed.
For milia that have stuck around for months, a dermatologist can extract them in a quick office visit. The standard technique involves nicking the surface of each cyst with a fine needle or small blade, then applying gentle pressure to push the keratin plug out. The procedure is minimally painful and rarely leaves a scar. For multiple milia or larger clusters, dermatologists sometimes use a low-current electrical technique that destroys the cyst with minimal scarring or changes in skin color afterward.
At-home approaches focus on encouraging skin cell turnover so keratin is less likely to get trapped. Products containing glycolic acid (a chemical exfoliant) or retinol can help. Some people report good results with glycolic acid toners in the 7% range, and gentle retinol serums designed for facial use can also speed turnover. Be cautious applying active ingredients close to your eyes. Start with a low concentration, apply a small amount, and keep the product on the orbital bone rather than the eyelid itself.
What you should not do is try to squeeze or lance milia at home. Unlike a pimple, there’s no pore opening to release the contents through. Attempting extraction with unsterilized tools risks infection and scarring in an area where your skin is delicate and heals visibly.
Preventing New Bumps
If you’re prone to milia, your skincare routine is the first thing to audit. Heavy, occlusive eye creams are a frequent trigger. Switch to lightweight, oil-free formulas and look for products labeled non-comedogenic, meaning they’re less likely to block pores and trap dead cells. The same goes for sunscreen: choose a lightweight or gel-based formula for the area around your eyes.
Regular gentle exfoliation helps keep the skin’s surface clear so dead cells shed normally. A mild glycolic or lactic acid product used a few times a week can make a noticeable difference over time. Sun protection also matters, since UV damage thickens the outer skin layer and makes milia more likely to form. Wearing sunglasses and applying sunscreen daily reduces that risk.
If milia keep coming back in the same area despite these changes, it may be worth seeing a dermatologist to check whether an underlying skin condition or medication is contributing. Certain steroid creams, for example, are known to trigger milia with prolonged use around the eyes.
