Milia are small, hard white bumps caused by dead skin cells trapped beneath the surface of your skin. They won’t pop like a pimple, and squeezing them only risks scarring or infection. The good news: most milia can be treated at home with the right skincare approach, and stubborn ones can be removed quickly by a dermatologist.
What Milia Actually Are
Milia are tiny cysts filled with keratin, the protein that makes up your outer layer of skin. They form when dead skin cells that would normally shed get trapped underneath new skin growth. Instead of flaking away, those old cells harden into a small, firm bump just below the surface. This is why milia feel solid to the touch and don’t have the soft, squeezable center of a whitehead.
There are two types. Primary milia appear spontaneously, usually on the face around the nose, cheeks, and eyelids, in areas with fine hair follicles. Secondary milia develop after some kind of skin damage: a burn, a blister, heavy sun exposure, or even prolonged use of thick creams that block the skin’s natural shedding process. Knowing which type you’re dealing with helps you figure out what to change in your routine.
Why You Should Never Squeeze Them
Milia sit deeper than whiteheads and are enclosed in a tough little sac of skin. There’s no open pore connecting them to the surface, so no amount of squeezing will push the contents out. What you’ll get instead is irritation, redness, and potentially a scar or infection that looks worse than the original bump. If you’ve been picking at a milium and it won’t budge, that’s exactly why.
At-Home Treatments That Work
The most effective home strategy is speeding up your skin’s natural cell turnover so the trapped keratin works its way out on its own. This won’t happen overnight, but consistent use of the right products can clear milia over several weeks.
Retinoids
Topical retinoids are the strongest over-the-counter option for milia. Adapalene (available without a prescription in many countries) and tretinoin (prescription-strength) both accelerate the rate at which your skin sheds dead cells and generates new ones. This helps break down existing milia and prevents new ones from forming. Apply a thin layer to the affected area at night, starting every other night to let your skin adjust. Dryness and mild peeling are normal in the first few weeks and actually signal the product is working.
Exfoliating Acids
If retinoids are too irritating or you want a gentler starting point, chemical exfoliants containing salicylic acid or glycolic acid can help. These dissolve the bonds between dead skin cells on the surface, making it easier for trapped keratin to eventually reach the surface. Look for leave-on products rather than wash-off cleansers, since the active ingredients need time on your skin to be effective. A product with 2% salicylic acid or 8 to 10% glycolic acid used a few times per week is a reasonable starting dose.
Lightweight Moisturizers and Sunscreen
Heavy, occlusive creams can contribute to milia by literally sealing dead cells against the skin. If you’re prone to milia, switch to oil-free, non-comedogenic moisturizers and sunscreens. This is especially important around the eyes, where milia commonly appear and where people tend to layer on rich eye creams. A lightweight gel formula is less likely to cause problems in that area.
Professional Removal Options
When milia don’t respond to topical treatment after a couple of months, or when you want them gone faster, a dermatologist can remove them in a single visit. The most common method is manual extraction: a doctor makes a tiny nick in the skin over each bump using a sterile needle or scalpel blade, then presses the keratin plug out with a small tool like a comedone extractor. It sounds more dramatic than it is. Each bump takes seconds, and the pinprick incisions heal quickly with minimal scarring.
Some estheticians also perform extractions, though regulations vary by state and some are not legally allowed to pierce the skin. If you go to an esthetician rather than a dermatologist, confirm they’re trained and permitted to do the procedure in your area.
For clusters of milia or bumps in tricky locations like the eyelids, dermatologists sometimes use electrocautery (a fine-tipped heated instrument) or a CO2 laser to remove the tissue. These methods destroy a tiny amount of skin and are typically reserved for cases where simple extraction isn’t practical. Recovery involves keeping the treated spots clean and moisturized while a small scab forms and falls off over a week or so.
How Long Milia Take to Clear
Milia can technically resolve on their own as your skin eventually cycles through and sheds the trapped cells, but this process is unpredictable. Some disappear in a few weeks. Others stick around for months or longer, especially in adults. In newborns, milia are extremely common and almost always clear within the first few weeks of life without any treatment at all.
If you’re using a retinoid or exfoliating acid, expect to see improvement within four to eight weeks of consistent use. Professional extraction gives the fastest results, with bumps gone immediately and the skin fully healed within days.
Milia vs. Similar-Looking Bumps
Not every small facial bump is a milium. Whiteheads (closed comedones) look similar but feel softer, contain oil and bacteria rather than hard keratin, and sit within a pore. They respond to acne treatments and can sometimes be extracted with gentle pressure. Milia are firmer, more dome-shaped, and completely sealed off from the pore.
Syringomas are another common lookalike, particularly around the eyes. These are small growths of sweat gland tissue that tend to be yellowish or skin-colored rather than bright white. Unlike milia, syringomas won’t respond to retinoids or exfoliation because they’re not caused by trapped dead skin. They require professional treatment with electrocautery or laser if you want them removed. If your bumps haven’t responded to several weeks of retinoid use, or if they cluster symmetrically under both eyes with a slightly yellowish tint, syringomas are worth considering.
Preventing New Milia
Once you’ve cleared your current milia, a few habits help keep them from coming back. Continue using a retinoid or chemical exfoliant a few times a week to maintain healthy cell turnover. Avoid thick, petroleum-based products on your face, especially around the eyes. Wear sunscreen daily, since UV damage thickens the outer layer of skin and makes it harder for dead cells to shed properly. Choose a lightweight, non-comedogenic formula.
If you notice milia forming repeatedly in the same spot after a skin injury, such as a rash, procedure, or sunburn, that area may be more prone to trapping keratin as it heals. Keeping the skin well-exfoliated during recovery can reduce the chance of secondary milia developing.
