Milia are tiny, hard white bumps caused by keratin trapped beneath the skin’s surface, and they won’t respond to squeezing the way a regular pimple does. Getting rid of them requires either patience, the right exfoliating products, or a quick in-office procedure from a dermatologist. The approach that works best depends on how many you have, where they are, and how long they’ve been there.
Why Milia Don’t Pop Like Pimples
A milium (the singular of milia) is a tiny cyst filled with keratin, the same protein that makes up your hair and the outer layer of your skin. Unlike a whitehead, which sits inside a pore and contains oil and bacteria, a milium is sealed beneath a thin layer of skin with no opening to the surface. That’s why pressing or squeezing does nothing productive. The keratin plug has nowhere to exit, and the pressure just damages the surrounding skin, risking scarring or infection.
On newborns, milia are extremely common and almost always disappear on their own within a few weeks. In adults, they’re more stubborn. Without treatment, adult milia can persist for months or indefinitely, which is why most people eventually look for ways to speed them along.
Over-the-Counter Products That Help
The most accessible route is using chemical exfoliants that gradually thin the layer of skin trapping the keratin plug. Three ingredients are worth knowing about:
- Salicylic acid penetrates into the pore lining and helps break down the keratin buildup. You’ll find it in acne cleansers, toners, and leave-on treatments, typically at 1 to 2 percent strength.
- Glycolic acid works on the skin’s surface to dissolve the bonds between dead skin cells, gradually exposing the trapped cyst. Look for it in serums or exfoliating pads.
- Adapalene (sold as Differin) is a retinoid available without a prescription. Retinoids loosen the keratin plug in milia and help push it toward the surface so the bump can resolve. Adapalene is the gentlest retinoid option and a good starting point if you haven’t used one before.
These products don’t work overnight. Expect several weeks of consistent use before you notice milia shrinking or disappearing. Apply them to clean, dry skin, and if you’re using a retinoid, start every other night to let your skin adjust. All three ingredients increase sun sensitivity, so daily sunscreen is non-negotiable while you’re using them.
Prescription Retinoids
If over-the-counter options aren’t cutting it after a couple of months, a dermatologist can prescribe a stronger topical retinoid. Prescription retinoids exfoliate the skin more aggressively than their OTC counterparts and are more effective at loosening the keratin plug, helping it reach the surface and clear. These are especially useful if you have clusters of milia or if they keep recurring. The tradeoff is more dryness, peeling, and irritation during the adjustment period, which typically lasts two to six weeks.
Professional Extraction and Procedures
For immediate results, a dermatologist or trained aesthetician can remove milia manually using a sterile needle or small blade to make a tiny incision in the skin, then gently press the keratin plug out. The procedure takes seconds per bump, causes minimal discomfort, and heals quickly with little to no scarring when done by a professional. This is the fastest option if you have a few stubborn milia, particularly around the eyes where topical acids can be irritating.
Superficial chemical peels are another in-office option, especially for people with widespread milia. These peels use higher concentrations of glycolic acid or salicylic acid than anything available over the counter, removing the top layers of skin in a controlled way. Most people experience mild redness and flaking for a few days afterward. A single peel can clear multiple milia at once, though some cases need a series of treatments spaced a few weeks apart.
What Triggers Milia in Adults
Understanding what causes milia helps you prevent new ones from forming while you’re treating existing bumps. The most common triggers in adults include:
- Heavy creams and ointments. Rich, occlusive products (especially thick eye creams) can trap keratin beneath the skin. If you’re prone to milia, switch to lighter, oil-free formulations.
- Sun damage. UV exposure thickens the outer layer of skin over time, making it harder for dead cells to shed normally. This creates the perfect conditions for keratin to get trapped.
- Skin injuries. Burns, blisters, rashes, and even aggressive cosmetic procedures can trigger secondary milia as the skin heals.
- Long-term steroid cream use. Prolonged application of topical steroids thins certain layers of the skin while disrupting normal cell turnover, which can lead to milia formation.
Reducing your risk comes down to a few practical habits: wear sunscreen daily, use heavy facial creams only temporarily rather than as a permanent routine, and don’t use steroid creams longer than prescribed.
Milia vs. Similar-Looking Bumps
Not every small bump on your face is a milium. A few conditions look similar but require different treatment.
Whiteheads (closed comedones) form inside pores and contain a mix of oil and dead skin cells. They’re softer than milia and respond to standard acne treatments. Milia feel hard and pearly, almost like a tiny grain of sand under the skin.
Syringomas are small, firm bumps caused by sweat gland overgrowth. They tend to cluster around the lower eyelids and are usually yellow or skin-toned rather than bright white. Unlike milia, syringomas won’t respond to exfoliants or simple extraction. A dermatologist can distinguish between the two with a physical exam, and in uncertain cases, a small skin biopsy confirms the diagnosis.
If your bumps are yellowish, flat, and sit on or near the eyelids, they could also be xanthelasma, which are cholesterol deposits unrelated to keratin. The treatment is entirely different, so getting the right diagnosis matters before you spend weeks applying products that won’t help.
A Practical Treatment Plan
If you have a handful of milia and want to try handling them at home first, start with a glycolic acid or salicylic acid exfoliant a few times per week. After your skin adjusts, you can add an OTC retinoid like adapalene on alternate nights. Give this routine at least six to eight weeks before judging results. During this time, swap any heavy moisturizers or eye creams for lightweight, non-comedogenic versions, and apply broad-spectrum sunscreen every morning.
If home treatment doesn’t clear them, or if you want faster results, professional extraction is quick and effective. For recurrent milia, a dermatologist can combine extraction with a prescription retinoid to both remove existing bumps and prevent new ones from forming. Most people find that once they adjust their skincare routine and address the underlying triggers, milia stop coming back.
