Under-eye milia are small, hard white bumps that sit just beneath the skin’s surface. They form when keratin, a protein your skin naturally produces, gets trapped inside tiny cyst-like structures near hair follicles or sweat ducts. Unlike whiteheads, milia have no opening to the surface, which is why they don’t pop like a pimple and can stick around for weeks or months.
What Milia Actually Are
Milia are technically tiny keratinizing cysts, not clogged pores. Each bump is a small pocket lined with layers of skin cells, filled with compacted keratin in the center. They typically measure 1 to 2 millimeters across and feel firm to the touch. The under-eye area is especially prone because the skin there is thinner than almost anywhere else on your body, and the region is packed with fine vellus hair follicles where these cysts tend to originate.
There are two types. Primary milia appear spontaneously, often without an obvious trigger. Secondary milia develop after some kind of skin disruption: a burn, a blister, heavy product use, or even aggressive exfoliation. The under-eye area sees both types, but secondary milia are particularly common here because people tend to layer rich eye creams and occlusives directly over this delicate skin.
Make Sure It’s Actually Milia
A few other things can look similar under the eyes, and they each require different treatment. Syringomas are firm, yellowish or skin-toned bumps that form in clusters near sweat ducts. They’re 1 to 3 millimeters in diameter, about the same size as milia, but they tend to have a slightly yellow or translucent tint rather than the bright pearly white of milia. Syringomas are sweat gland growths, not keratin cysts, so the removal approach is different.
Xanthelasma are flat or slightly raised yellowish patches, usually larger and less defined than milia. They signal elevated cholesterol in many cases and don’t respond to the same treatments at all. If your bumps are yellow, soft, or irregularly shaped rather than round, white, and hard, it’s worth getting a professional opinion before trying any removal strategy.
Why You Shouldn’t Extract Them Yourself
Milia have no pore opening, so squeezing them does nothing except damage the surrounding skin. Attempting to pierce or scrape them at home risks permanent scarring and infection. The under-eye area is especially unforgiving because the skin is so thin that even minor trauma can leave lasting marks or discoloration. Put down the needle and the comedone extractor.
Topical Treatments That Help
Retinoids are the most widely recommended topical option. They work by speeding up skin cell turnover, which helps the trapped keratin work its way to the surface over time. Over-the-counter retinol products (typically 0.25% to 0.5% concentration) are a reasonable starting point, though the under-eye area is sensitive, so you may need to apply only every other night at first to avoid irritation. Prescription-strength retinoids move faster but carry a higher risk of redness and peeling in this delicate zone.
Gentle chemical exfoliants containing alpha hydroxy acids like glycolic or lactic acid can also accelerate turnover. These won’t dissolve existing milia overnight, but consistent use over several weeks helps prevent new ones from forming and may gradually thin the layer of skin trapping the cyst, allowing it to resolve. Look for low-concentration formulas specifically designed for the eye area.
Topical approaches require patience. In adults, milia can take several weeks to a few months to clear with consistent product use. Some stubborn bumps never respond to topicals alone and need professional removal.
Professional Removal Options
Manual Extraction (Deroofing)
This is the most common and fastest method. A dermatologist uses a sterile needle or small blade to create a tiny opening in the skin over the cyst, then presses out the keratin plug. Results are immediate. The procedure is quick, usually takes just a few minutes for several milia, and the small wound heals within days. One downside: deroofing can leave behind a faint white mark (hypopigmentation), though on most skin tones this fades over time. Some estheticians also offer this service, but regulations vary by state, and not all are permitted to pierce the skin.
Cryotherapy
A dermatologist applies liquid nitrogen to freeze the milia, destroying the cyst. This is the same technique used for warts and other skin lesions. It’s effective, but the freezing can cause temporary redness or blistering, and in darker skin tones there’s a risk of pigment changes. For just a few small milia, deroofing is typically preferred because it’s more precise.
Laser Ablation
Laser treatment uses focused beams of light to vaporize the outer skin layers covering the cyst. It’s extremely precise, which makes it a good option for clusters of milia in a small area like the under-eye region. Recovery involves some redness and peeling, similar to a chemical peel. Laser ablation tends to cost more than manual extraction but may be recommended when milia are numerous or recurrent.
Preventing New Milia From Forming
The products you put around your eyes matter more than most people realize. Heavy occlusive ingredients create a physical seal over the skin that traps dead cells underneath, essentially setting the stage for new milia. The main culprits are petrolatum, mineral oil, lanolin, and thick synthetic waxes. Even heavy botanical oils applied thickly at night can contribute. This doesn’t mean you need to skip eye cream entirely, but switching to a lighter, gel-based formula can make a real difference if you’re prone to milia.
Sun protection also plays a role. UV damage thickens the outer layer of skin over time, making it harder for dead cells and keratin to shed normally. A lightweight, non-comedogenic sunscreen around the eyes helps keep that turnover process functioning smoothly. Mineral sunscreens (zinc oxide or titanium dioxide) sit on the skin’s surface and are generally less likely to contribute to milia than some chemical sunscreen formulas, though individual reactions vary.
If you use retinoids for treatment, continuing a low-concentration retinol as maintenance after your milia clear is one of the most effective prevention strategies. Regular, gentle exfoliation keeps the skin’s surface from building up the kind of thickened layer that traps keratin in the first place. The goal isn’t aggressive scrubbing. A mild chemical exfoliant two to three times a week is enough to keep the under-eye area turning over properly without irritating it.
