Milia are tiny, hard white bumps caused by keratin trapped beneath the skin’s surface. Unlike pimples, they can’t be squeezed out, because they sit inside a small cyst wall with no opening to the surface. Lancing (piercing the skin to create an opening) is the standard method dermatologists use to remove them, and while it’s a straightforward procedure, doing it yourself carries real risks of scarring and infection, especially on delicate facial skin.
Why Milia Can’t Be Popped Like Pimples
A milium (the singular of milia) is a tiny keratin-filled cyst sitting just below the outer layer of skin. It forms around the base of a fine hair follicle or sweat duct and is surrounded by layers of skin cells that create a sealed capsule. There’s no pore or opening connecting it to the surface, which is why squeezing does nothing except bruise the surrounding tissue.
This structure also explains why milia feel firm and pearly rather than soft like a whitehead. The keratin inside is compacted and solid, similar to what makes up your fingernails. To remove a milium, you have to physically break through the overlying skin and then dislodge or extract that solid core.
How Dermatologists Lance Milia
Professional extraction is quick and usually painless. The procedure takes just a few minutes, even for multiple milia. Here’s what typically happens:
- Skin is cleaned with an antiseptic to reduce bacterial contamination.
- A sterile needle or lancet is used to make a tiny puncture in the skin directly over the milium. The angle is shallow, just enough to break through the thin layer of skin covering the cyst. Some practitioners use insulin syringe needles or blood glucose lancets because the fine gauge minimizes tissue damage.
- The keratin core is extracted. A comedone extractor (a small metal loop tool) applies gentle, even pressure around the puncture to push the contents out. Some clinicians use the syringe itself as a suction device, drawing the contents out through the needle rather than pressing on the skin. This approach is particularly effective for smaller milia.
- The area is cleaned again and left to heal on its own.
The puncture is so small it typically closes within a day or two without any visible mark. There’s no stitching, no bandage, and minimal redness.
Attempting It at Home: What to Know
Many people attempt milia extraction at home, and the technique is mechanically simple. But the risks are worth understanding before you try. Infection is the primary concern. Facial skin has a rich blood supply, which means bacteria introduced through a non-sterile needle can spread quickly. Scarring is the other risk, particularly if you use too much pressure, go too deep, or work on areas with thin skin like around the eyes.
If you do attempt it on a milium located on your cheek, forehead, or chin (never the eyelid), cleanliness is everything. Wash your hands thoroughly. Use a brand-new, individually wrapped sterile needle or lancet. Clean the skin with rubbing alcohol before and after. Pierce only the very top of the bump at a shallow angle, just enough to create a tiny opening. Then use gentle lateral pressure with clean fingers or a sterilized comedone extractor to ease the hard white ball out. If it doesn’t come out easily, stop. Forcing it will damage the tissue and increase scarring risk.
Apply a thin layer of antibiotic ointment to the spot afterward and keep it clean for a few days. Avoid makeup on the area for at least 24 hours.
Where You Should Never Lance at Home
Eyelid milia are one of the most common locations people want to treat, and they’re the one area you should absolutely leave to a professional. The eyelid skin is the thinnest on the body, highly vascular, and sits directly over your eye. A slip with a needle here can cause permanent damage. Dermatologists and ophthalmologists have magnification tools and precise control that make eyelid extraction safe. At home, the margin for error is too small.
The same applies to milia clustered very close to the lip line, inside the nostril, or on the genitals. These areas are more prone to infection, slower to heal, and more likely to scar visibly.
Alternatives to Lancing
Not every milium needs to be lanced. Many resolve on their own over weeks to months as the skin naturally turns over. If you’d rather avoid a needle entirely, topical treatments can speed up the process.
Retinoids (vitamin A derivatives available over the counter as retinol or by prescription as tretinoin) increase the rate of skin cell turnover, which can help milia work their way to the surface and shed naturally. In one documented case, widespread milia that hadn’t responded to antibiotics or steroids cleared rapidly with topical tretinoin cream. Over-the-counter retinol products are gentler but work on the same principle, just more slowly.
Chemical exfoliants containing glycolic acid or salicylic acid also help by dissolving the bonds between dead skin cells, thinning the layer of skin trapping the cyst. These are especially useful for people who develop milia repeatedly. A glycolic or salicylic serum used a few times per week as part of your regular routine can reduce recurrence over time.
Preventing Milia From Coming Back
Milia often recur in the same areas, particularly around the eyes and on the cheeks. Heavy, occlusive skincare products are a common trigger. Rich eye creams, thick moisturizers, and petrolatum-based products can trap keratin beneath the surface in people who are prone to these cysts. Switching to lighter, non-comedogenic formulas often makes a noticeable difference.
Sun damage also plays a role. UV exposure thickens the outer layer of skin over time, making it harder for keratin to shed naturally. Daily sunscreen use helps keep skin texture normal and reduces the conditions that allow milia to form.
If you wear heavy eye makeup, remove it gently with a proper makeup remover rather than rubbing. Aggressive rubbing around the eyes irritates the delicate skin and can contribute to milia formation in that area.
Cost of Professional Removal
Because milia are cosmetic rather than medically dangerous, insurance almost never covers their removal. Extraction falls into the same category as facials and chemical peels, which most plans consider elective. Out-of-pocket costs vary widely depending on your location and the number of milia being treated, but a dermatology office visit for extraction typically runs anywhere from $100 to a few hundred dollars. Some estheticians also perform milia extractions at a lower price point, though they may not be able to treat eyelid milia or use certain tools that require a medical license.
