A small white bump under your eye is most likely a milium (plural: milia), a tiny cyst filled with a protein called keratin that gets trapped beneath the skin’s surface. These are extremely common, completely harmless, and one of the top reasons people search for bumps in this area. But not every bump under the eye is a milium. Depending on the size, color, texture, and how long it’s been there, it could also be a syringoma, a chalazion, a cholesterol deposit, or occasionally something that deserves a closer look.
Milia: The Most Common Cause
Milia are small, dome-shaped white cysts that sit just under the surface of the skin. They typically measure 1 to 2 millimeters across and look like tiny pearls or grains of sand embedded in the skin. Unlike a pimple, a milium feels firm to the touch and has no redness or inflammation around it. You can’t squeeze one out the way you would a whitehead, because the keratin inside is trapped in a small pocket that doesn’t connect to the skin’s surface.
The area under the eyes and on the eyelids is one of the most common spots for milia to appear. They affect both children and adults. In newborns, milia (sometimes called “milk spots”) show up at birth and typically clear on their own within a few weeks. In adults, milia can stick around indefinitely.
Several things can trigger milia formation. Sun damage, burns, blisters, or rashes can all cause secondary milia by disrupting the skin’s normal shedding process. Heavy eye creams and ointments are another well-known culprit. Rich, occlusive products can block the skin’s natural exfoliation cycle and trap dead skin cells underneath. If you started noticing white bumps after switching to a thicker moisturizer or eye cream, that product is a likely contributor.
Syringomas: Clusters of Skin-Colored Bumps
Syringomas are another common cause of small bumps under the eyes, though they look a little different from milia. These are benign growths that develop from overactive sweat glands in the skin. They tend to appear as clusters of small, rounded bumps that are skin-colored or slightly yellowish rather than bright white. Each bump is usually 1 to 3 millimeters across.
The key difference between syringomas and milia is their origin. Milia are keratin-filled cysts sitting near the skin’s surface, while syringomas are deeper growths rooted in the sweat ducts. Syringomas are more common in women, often appear during adolescence or early adulthood, and tend to be persistent. They’re completely harmless but don’t resolve on their own.
Xanthelasma: Yellowish Patches Near the Nose
If the bump under your eye is more yellow than white and looks like a flat or slightly raised patch rather than a round cyst, it could be xanthelasma. These are cholesterol deposits that build up under the skin, typically appearing near the inner corners of the eyelids closest to your nose. They tend to be larger than milia, sometimes growing to a centimeter or more, and have a soft, waxy texture.
About half of people with xanthelasma have elevated cholesterol levels, which makes these patches worth mentioning to your doctor even though the deposits themselves are harmless. The other 50% have normal cholesterol. Still, xanthelasma can signal that it’s worth checking your lipid levels, especially if you haven’t had bloodwork recently.
Chalazion: A Firm Bump on the Eyelid
A chalazion forms when one of the oil-producing glands in the eyelid gets clogged and swells into a firm, round bump. Unlike a stye, which is a painful, red, infected lump that grows at the base of an eyelash, a chalazion usually sits farther back on the eyelid and isn’t particularly painful. It can range from the size of a pea to something noticeably larger.
Chalazia are more pink or skin-colored than white, and they tend to develop over days rather than appearing suddenly. Warm compresses applied for 10 to 15 minutes several times a day help the clogged gland open and drain. Most chalazia resolve within a few weeks with this approach alone.
Molluscum Contagiosum: A Viral Bump
Less commonly, a bump near the eye can be molluscum contagiosum, a viral skin infection. These bumps are raised, round, and skin-colored with a distinctive small dent or dimple right at the center. That central indentation is the hallmark feature. Molluscum bumps are contagious and can spread to other parts of the body or to other people through direct contact. They’re more common in children but can appear in adults as well.
When a Bump Needs Attention
Most white bumps under the eye are benign, but certain features should prompt a closer look. Basal cell carcinoma, the most common type of skin cancer, can appear on the eyelid or around the eye as a shiny, translucent bump that looks pearly white or pink. On darker skin tones, it may appear brown or glossy black. Tiny blood vessels may be visible on or near the surface. The key red flags are a bump that slowly grows over time, changes in appearance, bleeds or crusts, or looks like a sore that won’t heal. A white, waxy, scar-like patch without a clear border is another presentation to watch for.
Any bump that changes shape, bleeds, feels painful without explanation, or has been growing steadily over weeks or months is worth having a dermatologist evaluate.
Removal and Treatment Options
Milia sometimes resolve on their own, especially in infants, but adult milia under the eyes often persist. The most straightforward removal method is extraction with a tiny sterile needle or blade, done by a dermatologist in a quick office visit. Cryotherapy, which freezes the milia with liquid nitrogen, is another common option. Laser treatment and heat-based removal are also used.
Trying to pop or extract milia at home is risky, particularly around the eyes. The skin here is extremely thin and delicate. Attempting to pierce a milium with an unsterilized needle can introduce bacteria, cause infection, or leave a scar in a highly visible area. The cyst wall also needs to be fully removed, or the milium will simply refill.
Syringomas have a different set of treatment options because they sit deeper in the skin. Electrosurgery uses radio-wave or sound-wave energy to generate heat beneath the surface and break down the growths. Laser therapy, dermabrasion, and surgical excision are also effective. Syringomas can sometimes recur after removal.
For xanthelasma, treatment addresses both the cosmetic concern and the potential underlying cholesterol issue. The deposits themselves can be removed through similar procedures (laser, surgery, cryotherapy), but if cholesterol levels are elevated, managing those levels helps prevent new deposits from forming.
Preventing New Bumps
If you’re prone to milia under the eyes, a few changes can reduce your chances of developing new ones. Swap heavy, occlusive eye creams for lighter, gel-based formulas. Gentle chemical exfoliation with products containing low concentrations of retinol or alpha-hydroxy acids can help keep dead skin cells from building up, though you should use these cautiously around the eye area since the skin is sensitive. Wearing sunscreen daily also matters: UV damage is a known trigger for milia because it thickens the outer layer of skin and traps keratin underneath.
For chalazia, keeping the eyelids clean and occasionally using warm compresses can help prevent oil glands from clogging. If you wear eye makeup, removing it thoroughly every night reduces the chance of blocked glands.
