Milia are tiny, harmless cysts that form when keratin (a skin protein) becomes trapped just beneath the skin. Although they’re sometimes called “fat cysts,” that’s not accurate—they do not contain fat.
What you can do
- Leave them alone. Many milia, especially in infants, disappear on their own.
- Use gentle exfoliation. Products containing retinoids (for adults), alpha hydroxy acids (AHAs), or beta hydroxy acids (BHAs) may help prevent new milia from forming over time.
- Protect your skin from the sun. Sun damage can contribute to skin changes that make milia more likely.
- Use non-comedogenic skincare products if you’re prone to clogged pores.
What not to do
- Don’t squeeze, pick, or try to pop milia with a needle. This can cause infection, scarring, or skin damage.
- Avoid harsh scrubs or aggressive exfoliation, which can irritate the skin.
When to see a dermatologist
A dermatologist can remove persistent milia safely using a sterile needle or a small incision, sometimes with other treatments depending on the location and type of milia.
Seek medical advice if:
- the bumps change rapidly, bleed, or become painful,
- they appear in large numbers suddenly,
- you’re unsure whether they’re milia or another skin condition.
If you have a photo of the bumps, I can help you determine whether they look like milia or another common skin condition (though I can’t diagnose them from an image alone).
