Those little bumps under your eyes are most likely milia, tiny cysts formed by dead skin cells trapped beneath the surface. They’re the single most common cause of small, painless bumps in the under-eye area. But several other conditions can look similar, and telling them apart matters because each one has a different cause and a different path to clearing up.
Milia: The Most Common Culprit
Milia are small white or yellowish bumps that often appear in clusters under the eyes. They form when dead skin cells don’t shed normally. Instead of flaking off, they get buried under new skin growth, harden, and turn into tiny cysts just below the surface. They feel firm to the touch and don’t pop like a pimple, no matter how tempting it is to try.
Unlike acne, milia aren’t caused by bacteria or clogged pores in the traditional sense. They’re not inflamed, they don’t hurt, and they don’t turn red. Many people develop them without any obvious trigger, but heavy skincare products are a well-known contributor. Thick creams containing ingredients like shea butter, dimethicone, coconut oil, or petroleum jelly can create too much of a seal over the skin, trapping cells underneath. If your under-eye bumps appeared after switching to a richer eye cream or moisturizer, that product is worth reconsidering.
Milia can resolve on their own over weeks or months, but stubborn ones often stick around. A dermatologist can remove them quickly with a sterile needle or small blade in a process called extraction. Trying to pick, scratch, or pop milia at home can lead to scarring, bruising, or infection, especially in the delicate skin under the eyes. Leave removal to a professional.
Syringomas: Skin-Colored and Clustered
If your bumps are skin-colored or slightly yellowish rather than white, and they’ve been there for a long time without changing, they may be syringomas. These are caused by an overgrowth of cells in your sweat glands. Each bump is typically 1 to 3 millimeters across, firm, and round. They tend to appear in symmetrical clusters, with both sides of the face affected in a similar pattern.
Syringomas are completely harmless but permanent. They won’t go away with skincare products or home treatments. For people who want them removed for cosmetic reasons, laser treatment is the most common professional option. CO2 lasers are the most widely used, though newer fractional laser techniques reduce recovery time and lower the risk of side effects like scarring or discoloration. Non-ablative fractional lasers offer an easier recovery but may need multiple sessions.
Sebaceous Hyperplasia: Bumps With a Dent
Sebaceous hyperplasia looks like small bumps, usually 2 to 6 millimeters across, that are skin-colored, yellow, or brown. The defining feature is a small dent or indentation in the center of each bump. These form when oil glands in the skin become enlarged, something that happens more often with age as hormone levels shift.
These bumps are benign and don’t require treatment unless they bother you cosmetically. They’re more common on the forehead and cheeks but can appear under the eyes as well. A dermatologist can distinguish them from other conditions by that characteristic central dimple.
Xanthelasma: Flat Yellow Patches
Xanthelasma looks a bit different from the other conditions on this list. Rather than round bumps, these are soft, flat or slightly raised yellowish patches that typically appear on the inner corners of the upper or lower eyelids. They’re deposits of cholesterol under the skin.
What makes xanthelasma worth paying attention to is what it can signal about your overall health. Roughly 50% of people who develop xanthelasma have abnormal cholesterol levels, often linked to inherited cholesterol disorders. If you notice yellowish, flat patches near your eyes, getting your cholesterol checked is a reasonable next step. The patches themselves are harmless to the skin, but they point toward cardiovascular risk that’s worth knowing about.
Periorbital Dermatitis: Red, Scaly Bumps
If your under-eye bumps are pink or red, slightly scaly, or surrounded by irritated skin, you may be dealing with periorbital dermatitis. This inflammatory condition causes small papules or pustules around the eyes, nose, or mouth. It’s most common in young adult women, though anyone can develop it.
The strongest known trigger is topical steroid use on the face. Steroid creams initially improve the rash, but the condition rebounds and worsens when you stop applying them, which can trap people in a frustrating cycle. Other triggers include fluorinated toothpaste, certain sunscreens, cosmetics, and prolonged face mask use. Treatment typically starts with stopping the steroid entirely, though your skin will likely flare before it improves. This is one condition where professional guidance makes a real difference, since managing the rebound period takes a clear plan.
Signs That Need Professional Evaluation
Most under-eye bumps are harmless, but a few features should prompt a closer look. A bump that bleeds, develops a pearly or rolled border, grows steadily over weeks, or becomes an open sore that won’t heal could be a sign of skin cancer. Basal cell carcinoma, the most common type, often appears as a skin-colored or pink bump on lighter skin, or a brown to glossy black bump on darker skin. Pain or itching around a bump that wasn’t there before also warrants attention.
Preventing New Bumps
If milia are your issue, the most practical prevention strategy is rethinking what you put on the skin around your eyes. Switch from heavy, occlusive eye creams to lighter, gel-based formulas. Avoid layering petroleum jelly, thick butters, or silicone-heavy products directly on the under-eye area. Regular gentle exfoliation of the face can help dead skin cells shed normally rather than building up, though be careful with exfoliants near the eyes since the skin there is thin and easily irritated.
Sun damage also contributes to milia formation over time by thickening the outer layer of skin and making it harder for dead cells to shed. A lightweight, non-comedogenic sunscreen (rather than a thick, greasy one) protects without creating the occlusion problem. For syringomas and sebaceous hyperplasia, there’s no reliable prevention since both are driven by your body’s gland activity rather than external products.
