Milia are small, hard white bumps that form when dead skin cells get trapped beneath the surface of your skin. They’re not pimples, and squeezing them won’t work. The good news: most milia can be treated at home with the right skincare approach, and stubborn ones are easily removed by a dermatologist in a quick office visit.
What Milia Are and Why They Form
Your skin constantly sheds dead cells to make room for new ones. Milia form when that process stalls. Instead of falling away, old skin cells get buried under new growth, harden, and form tiny cysts filled with a protein called keratin. They typically show up on the eyelids, forehead, and cheeks as firm, pearly-white bumps about 1 to 2 millimeters across.
There are two types worth knowing about. Primary milia appear on their own, with no obvious trigger, and are extremely common in both adults and newborns. Secondary milia develop after your skin has been damaged by burns, blisters, rashes, or excessive sun exposure. They can also form as a reaction to heavy, occlusive skin creams. Understanding which type you have helps determine whether you need to change your skincare routine or simply treat the bumps themselves.
At-Home Treatments That Actually Help
Because milia sit beneath a sealed layer of skin, they don’t respond to spot treatments the way acne does. You can’t pop them, and trying to pick at them with a needle at home risks scarring and infection. What does work is encouraging faster skin cell turnover so the trapped material works its way out naturally.
Over-the-counter products containing salicylic acid or glycolic acid are your best starting options. Salicylic acid is a beta hydroxy acid that penetrates into pores and helps dissolve the buildup of dead cells. Glycolic acid is an alpha hydroxy acid that loosens the bonds between surface skin cells, promoting exfoliation. Look for leave-on serums or toners with these ingredients and use them consistently for several weeks. Milia won’t vanish overnight; you’re gradually thinning the skin over the cyst so the contents can escape.
A retinol product can also speed things along. Retinol increases cell turnover across the entire skin surface, which makes it harder for dead cells to get trapped in the first place. If you’re new to retinol, start with a lower concentration a few nights per week to avoid irritation, then build up.
Professional Removal Options
If at-home exfoliation hasn’t cleared your milia after a couple of months, or if you have a cluster that bothers you cosmetically, a dermatologist can remove them in minutes. The most common method is manual extraction: the dermatologist nicks the surface of the milium with a small blade, then gently applies pressure to pop the intact cyst out through that tiny opening. It’s fast, precise, and usually heals without a mark.
For more widespread or stubborn milia, dermatologists have additional tools:
- Cryotherapy: Liquid nitrogen is sprayed or dabbed onto each milium with a cotton swab, freezing and destroying the cyst. This is the same technique used for warts and other small skin growths.
- Laser ablation: A focused laser beam removes the outer layer of skin over the milium and vaporizes the cyst contents without damaging surrounding tissue. It’s extremely precise and works well for milia near the eyes.
- Chemical peels: A professional-strength solution containing glycolic or salicylic acid is applied to the skin to remove several layers at once, clearing multiple milia in a single session.
Most of these procedures involve minimal downtime. You might have some redness or slight swelling for a day or two, but the skin heals quickly because milia sit so close to the surface.
Skincare Ingredients to Avoid
If you keep developing new milia, your moisturizer or eye cream could be the culprit. Heavy, occlusive ingredients seal a thick barrier over the skin that can trap dead cells underneath. The biggest offenders are mineral oil derivatives. Check your product labels for liquid paraffin, liquid petroleum, paraffinum liquidum, and petrolatum liquid. These are all forms of mineral oil that are particularly likely to trigger milia in people who are prone to them.
Lanolin is another common trigger. It’s a thick, greasy oil derived from sheep’s wool and used as an emollient in many moisturizers and lip products. If you notice milia forming around the areas where you apply a lanolin-heavy product, switching to a lighter, non-comedogenic formula often solves the problem on its own. Gel-based moisturizers and oil-free sunscreens are generally safer choices for milia-prone skin.
Milia in Babies
Nearly half of all newborns develop milia, usually across the nose, cheeks, and chin. These tiny white bumps look alarming but are completely harmless. A baby’s skin is still learning to shed cells efficiently, and the bumps typically resolve on their own within a few weeks to a couple of months without any treatment. You don’t need to apply creams, scrub the area, or try to remove them. Just wash your baby’s face gently with water and let the skin do its work.
How to Tell Milia From Similar Bumps
Several other skin conditions look like milia at first glance. Syringomas are small, yellowish or skin-toned bumps caused by sweat gland overgrowth. They tend to cluster around the eyes and, unlike milia, won’t respond to exfoliation because they’re glandular tissue rather than trapped dead skin. Sebaceous hyperplasia produces slightly larger, yellowish bumps with a central dimple, caused by enlarged oil glands. Closed comedones (whiteheads) can also look similar, but they’re softer and more easily expressed than the hard, pearl-like texture of a milium.
If you’re unsure what you’re dealing with, a dermatologist can usually tell by looking. In rare cases where the diagnosis isn’t clear, a small skin biopsy confirms what’s going on. This matters because each condition has a different treatment path, and exfoliating acids that work well for milia won’t do anything for syringomas.
Preventing New Milia
Once you’ve cleared existing milia, keeping them from coming back is mostly about maintaining good skin cell turnover and avoiding pore-clogging products. A consistent routine with a gentle exfoliant two to three times a week goes a long way. Sun protection also matters: UV damage thickens the outer layer of skin, making it easier for dead cells to become trapped. Use a lightweight, non-comedogenic sunscreen daily.
If you’ve had secondary milia after a skin injury, the area is more likely to develop new ones as it heals. Keeping the healing skin moisturized with a light, non-occlusive product and avoiding heavy ointments in that area reduces the risk. Over time, as the skin fully repairs itself, the tendency to form milia in that spot usually fades.
