Those small white dots under your eyes are most likely milia, tiny cysts filled with a protein called keratin that gets trapped beneath the skin’s surface. They’re harmless, painless, and extremely common. In most cases they resolve on their own within a few weeks to a couple of months, though some stick around longer. A few other conditions can look similar, so it’s worth knowing the differences.
Milia: The Most Likely Cause
Milia form when bits of dead skin cells get trapped just below the surface and harden into a small, firm ball. The material inside is keratin, the same protein found in your hair and outer skin layer. They show up as small white or yellow bumps, usually two millimeters or smaller, on your eyelids, under your eyes, or across your cheeks and nose. Unlike pimples, milia don’t have an opening to the surface, which is why they feel hard and can’t be squeezed out like a whitehead.
In adults, milia typically clear up on their own within a few weeks to a couple of months. They aren’t caused by poor hygiene, and they’re not a sign of a skin disease. Some people are simply more prone to them than others.
Why Skincare Products Sometimes Trigger Milia
Heavy, occlusive eye creams are one of the more common triggers. These products work by sealing moisture into the skin with a barrier on top, but that same barrier can interfere with the skin’s natural process of shedding dead cells. Ingredients to watch for include mineral oil, petroleum, beeswax, lanolin, squalene, and dimethicone. If you notice milia forming after switching to a richer eye cream, the product may be contributing. Switching to a lighter, non-occlusive formula often helps prevent new ones from appearing.
Other Conditions That Look Similar
Syringomas
Syringomas are small, round bumps caused by an overgrowth of cells in your sweat glands. They tend to cluster on and around the lower eyelids and are typically 1 to 3 millimeters across. Unlike milia, which are bright white, syringomas are often yellow, translucent, or skin-colored. They’re completely benign but don’t go away on their own. If their appearance bothers you, a dermatologist can discuss removal options.
Xanthelasma (Cholesterol Deposits)
Xanthelasma appears as flat or slightly raised yellow patches near the inner corners of the eyelids, close to the nose. These are cholesterol deposits in the skin, and they can be soft, chalky, or semi-solid. They tend to be larger and flatter than milia, making them fairly easy to distinguish once you know what to look for. A provider who spots xanthelasma will often want to check your cholesterol levels, since the deposits can signal elevated blood lipids even when you feel perfectly healthy.
Fordyce Spots
Fordyce spots are enlarged oil glands that appear in areas without hair follicles. They look like tiny white, yellow, or pale bumps, typically 1 to 3 millimeters across (about the size of a sesame seed at most). They sometimes appear as isolated spots, but they can also cluster in groups of 50 or more. Fordyce spots are harmless and don’t require treatment. They’re most commonly found on the lips and inside the cheeks, but can occasionally show up near the eyes.
Why You Shouldn’t Try to Pop Them
It’s tempting to squeeze milia the way you’d pop a pimple, but the structure is different. Milia sit in a tiny pocket beneath the skin with no pore opening at the surface. Squeezing forces pressure into the surrounding tissue rather than pushing anything out. Around the eyes, the skin is exceptionally thin and the blood vessels are close to the surface, so aggressive squeezing can cause bruising, broken capillaries, or scarring that looks worse than the original bump.
If a milium bothers you and hasn’t resolved after a couple of months, a dermatologist can extract it with a small sterile needle or blade in a quick office visit. This controlled approach avoids the tissue damage that DIY attempts cause.
Gentle Approaches That Can Help
For milia, regular gentle exfoliation encourages the natural turnover of dead skin cells that prevents keratin from getting trapped. Products containing a low concentration of retinol or a mild alpha hydroxy acid can speed up cell turnover around the eye area. Start slowly, since the skin under the eyes is sensitive and can become irritated quickly. Keeping the area clean and avoiding thick, greasy products at night reduces the chance of new milia forming.
For syringomas and xanthelasma, over-the-counter products won’t make a meaningful difference. These require professional treatment if you want them removed.
Signs a Bump Needs Medical Attention
Most white dots under the eyes are completely harmless, but certain changes warrant a closer look. A bump that keeps growing over weeks, changes color, becomes painful, or develops into a sore that won’t heal could indicate something other than milia. Basal cell carcinoma, the most common type of skin cancer, frequently appears on sun-exposed areas of the face and can initially look like a small, pearly bump. On lighter skin it often appears pink or skin-colored with a slightly rolled edge. On darker skin tones it may look brown or glossy black. Any bump that itches persistently, bleeds, or changes in appearance over time is worth having a dermatologist evaluate.
