BBCnews is carrying this article discussing a nifty find at a recent UK excavation:

The fashion conscious women of Roman Britain used a tin-based foundation to get a pale and appealing look.

The evidence comes from a sealed pot of ointment found at an archaeological dig in Southwark, south London, last year.

I could have sworn we covered this when it first broke last year, but I couldn't find anything digging through the archives. Of course, as big as this place is now that doesn't mean too much. At any rate, a really interesting find!
