Retinoid and extraction
Milia ( sing. milium from Latin Millet seed) are small cysts, filled with keratin. They can be extracted quite easily by poking a hole in them, expressing the contents with either a comedone extractor or forceps and then trying to squeeze the whole thing out of the skin.
To prevent them, you should be prescribed a Retinoid, a vitamin A derivative such as Retin A. Something that aesthetilcians do quite nicely is a deep pore cleanser with extraction. You might call your local spa for this...
