The mascara Ruby used was the new 'Stila Wet Masacra'. It is a water-based gel formula for a sexy, wet, "just-stepped-out-of-the-shower" look. It is avaliable in blue or green, which is pretty and fun for the summer, giving just a hint of vivid colour.
But be quick they are Limited Edition!!!
Pout do a similar product called 'Wet Lash'. It is avaliable in clear and can be worn on it's own or layered over your favorite mascara for a dewy look.
Both available from London department stores, Sephora and via mail order.
Website
www.pout.co.uk (also has a Covent Garden boutique).
Stila has a website, but does not ship outside the US and I think they may have already sold out of the Wet Mascara.
Sephora has a website
www.sephora.com. Does not yet have it's UK store online, but if you click on 'United States' it will take you to the American version and I think they ship outside US.
Hope this helps!
Have fun.
