Milia are tiny white or yellowish bumps that form just beneath the surface of the skin, and the under-eye area is one of the most common places they appear. Each bump is a small cyst filled with keratin, a protein your skin naturally produces. Unlike pimples, milia have no opening to the surface, which is why they don’t pop like a whitehead and can stick around for weeks or months.
How Milia Form
Your skin constantly sheds dead cells to make room for new ones. Milia develop when that process stalls. Instead of sloughing off, dead skin cells get trapped beneath a layer of new skin, harden, and form a tiny cyst. The result is a firm, dome-shaped bump typically 1 to 2 millimeters across.
The under-eye area is especially prone because the skin there is thinner and more delicate than almost anywhere else on your body. That thinness makes it easier for dead cells to become trapped, and it also makes the white bumps more visible once they form.
Common Causes and Triggers
Milia fall into two broad categories. Primary milia appear on their own, without any clear trigger, when dead skin simply doesn’t shed properly. These are the same “milk spots” that are extremely common on newborns’ faces. In babies, they almost always resolve on their own within a few weeks. In adults, primary milia tend to be more persistent.
Secondary milia form after something damages or disrupts the skin. Common triggers include:
- Heavy eye creams or ointments that create an occlusive barrier, trapping dead cells underneath
- Sun damage, which thickens the outer layer of skin and slows cell turnover
- Burns, blisters, or rashes that injure the skin surface
- Long-term use of steroid creams around the eye area
If you’ve recently switched to a richer moisturizer or eye cream and noticed new bumps, the product itself may be the culprit. Formulas that sit heavily on the skin can seal dead cells in place rather than letting them shed naturally.
How to Tell Milia From Other Under-Eye Bumps
Several conditions look similar to milia but have different causes and treatments, so getting the identification right matters. Milia are pearly white, very small (1 to 2 millimeters), and feel firm to the touch. They sit right at the skin’s surface and don’t itch, hurt, or change color when you press on them.
Syringomas are another common under-eye bump that people mistake for milia. These are small sweat gland growths, typically yellow or skin-colored, that also cluster around the eyes. They tend to be slightly larger (1 to 3 millimeters) and have a flatter, more blended appearance compared to the distinct white dot of a milium. A dermatologist can distinguish the two on sight, and if there’s any doubt, a small skin biopsy confirms the diagnosis.
Xanthelasma, flat yellowish patches around the eyelids, are cholesterol deposits and look quite different from the round, raised bumps of milia. If your bumps are soft, flat, and yellowish rather than white and dome-shaped, that’s a different condition worth having evaluated.
Why You Shouldn’t Try to Pop Them
Because milia look like tiny whiteheads, the temptation to squeeze them is strong. But unlike a pimple, a milium has no pore opening connecting it to the surface. Squeezing just compresses the cyst against the surrounding tissue without releasing anything. Around the eyes, where the skin is thin and full of small blood vessels, this can cause bruising, broken capillaries, infection, or scarring that’s harder to treat than the original bump.
Professional Removal Options
If milia bother you cosmetically, a dermatologist can remove them in a quick office visit. The two most common approaches are:
- Deroofing: A sterilized needle is used to carefully lift the thin layer of skin over the cyst, then the hardened keratin plug is eased out. Results are immediate, and the procedure takes only a few minutes.
- Laser ablation: A small, precisely targeted laser opens the cyst and removes the keratin buildup. This option works well for clusters of milia or bumps in tricky locations very close to the eye. The laser removes only the outermost layer of skin, leaving surrounding tissue intact.
Both procedures are minimally invasive. The skin around the treated area may look slightly pink for a day or two, but recovery is fast and scarring is rare when done by a trained professional.
Preventing New Milia
You can reduce the chances of milia forming (or returning) by adjusting a few parts of your skincare routine.
Gentle exfoliation helps keep dead skin cells from building up. Cleansers or serums containing salicylic acid, glycolic acid, or citric acid encourage cell turnover without requiring you to physically scrub the delicate under-eye area. Chemical exfoliation is preferable to gritty scrubs around the eyes, where the skin tears easily.
Retinoids (or the milder over-the-counter form, retinol) speed up the rate at which your skin renews itself, making it harder for dead cells to get trapped. If you’re adding a retinoid product to your routine, use it once per day, ideally at night, and introduce it gradually since it can cause dryness and irritation at first. The skin under the eyes is sensitive, so starting with a low-strength retinol and working up is a safer approach than jumping to a prescription-strength product.
Sunscreen with SPF 30 or higher protects the under-eye skin from the UV-driven thickening that contributes to milia. If your skin is very sun-sensitive, SPF 50 or higher adds an extra margin of protection. Look for lightweight, non-comedogenic formulas rather than heavy creams that could contribute to the problem.
Switching away from thick, occlusive eye creams is one of the simplest changes you can make. Lightweight gels or serums deliver hydration without sealing the skin’s surface shut. If you suspect a specific product triggered your milia, stop using it for a few weeks and see whether new bumps stop appearing.
How Long Milia Last Without Treatment
In newborns, milia typically disappear on their own within a few weeks as the baby’s skin matures. Adults aren’t as lucky. Because adult skin is thicker and turns over more slowly, milia can persist for months, and some never resolve without intervention. They’re completely harmless from a medical standpoint, so leaving them alone is a valid option if they don’t bother you. But if they do, professional removal is straightforward, and the right skincare adjustments can keep them from coming back.
