How can you treat milia?

Dermatologist: Try using gentle exfoliation products. Avoid harsh skin-care products. Sometimes they go away on their own. A dermatologist can remove them using a scalpel or curette, but this is time-consuming and expensive. Milia are not harmful, but they are a cosmetic nuisance.

Depends at what age: In newborn it's normal, no treatment required, in adults - probably laser. But i would ask dermatologist or a plastic surgeons for sure.
