What milia are
Milia (one bump is a milium) are tiny, firm, dome-shaped bumps that look white or yellowish. They are usually only a millimeter or two across. Despite appearances, they are not pimples. Each one is a small cyst that forms just under the surface of the skin when keratin, the protein that makes up the outer layer of skin, becomes trapped in a tiny pocket.
They are harmless and not contagious, and they do not hurt or itch. Many people notice them around the eyes, on the eyelids, cheeks, nose and forehead, though they can appear elsewhere.
Milia versus whiteheads
Milia are often mistaken for whiteheads, and the confusion leads to the most common mistake, which is trying to squeeze them. The two are different in useful ways.
- Whiteheads are clogged pores filled with oil and dead skin cells. They are often softer, may sit on a slightly red or inflamed base, and can come and go in the same spots.
- Milia are keratin trapped beneath the surface with no opening to the skin. They feel hard, stay in place for weeks or months, and do not have a pore to empty through.
If you are dealing with blocked pores and breakouts, that falls under the broader topic of acne and related care, including blackheads. Milia need a different mindset.
Why they form
There are a few general types:
- In newborns: Many babies have milia, often on the nose and cheeks. They usually clear on their own within weeks without any treatment.
- Primary milia in older children and adults: These appear without an obvious reason. They may be linked to the skin’s natural shedding process not working perfectly in a small spot.
- Secondary milia: These form after the skin has been damaged or disturbed, for example following blistering conditions, burns, significant sun damage, certain procedures or prolonged use of strong topical medications. The healing skin can trap keratin as it repairs.
Heavy or rich products near the eyes are sometimes blamed. The evidence is not clear, and milia can occur in people who use very simple routines, so it is best not to assume that any single product is responsible. If you notice that new bumps appear after you start something, you can pause it and see, but that is a guess rather than a rule.
Why not to pick at them
It is tempting to dig at a small white bump, but milia do not behave like pimples:
- There is no pore opening, so squeezing is unlikely to remove the contents and tends to just damage the surrounding skin.
- Picking can cause redness, scabs, infection, scarring and dark marks. The skin around the eyes is especially thin and delicate.
- Needles, pins or other homemade tools can introduce bacteria. This applies to anything that breaks the skin without proper sterile technique.
- Damage from picking can itself lead to more bumps, as secondary milia can follow skin injury.
The reasons for avoiding picking pimples apply even more strongly here.
What helps in general
Many milia go away on their own over weeks to months, particularly in infants. For persistent ones in older children and adults, general habits that support healthy skin turnover may be useful, though none is guaranteed to make milia disappear:
- Use a gentle cleanser and avoid harsh scrubbing.
- Be careful with exfoliation. Gentle chemical exfoliants are sometimes used by people for this purpose, but overdoing it can irritate skin, and the eye area is sensitive. Over-exfoliation can damage the barrier. Speak with a professional before using actives near the eyes.
- Use sunscreen daily, since sun damage can contribute to skin changes over time.
- Choose light, non-greasy products around the eyes if you find your bumps cluster there, while keeping in mind that this is a gentle experiment and not a proven fix.
- Be patient. Improvement is usually slow, and some milia stay for a long time.
Professional removal
If the bumps bother you, a dermatologist or other qualified clinician can remove milia. This is typically done by making a tiny opening with a sterile instrument and gently lifting out the contents. Other approaches exist, and what is suitable depends on the person and location. Because it involves breaking the skin near sensitive areas, it should be done by a trained professional rather than at home.
When to ask for a check
See a professional if:
- You are unsure whether a bump is a milium, since other small bumps can look similar
- A bump is growing, red, painful, bleeding, or changing
- Many bumps appear suddenly or after a skin injury or blistering illness
- A baby has bumps that are spreading, inflamed or not settling
New or changing spots on the skin always deserve a proper look, so do not assume every small white bump is a milium.
Milia are nearly always a cosmetic matter rather than a health concern. Leaving them alone is a reasonable choice, and outcomes vary from person to person.
