I read your post and thought I might be able to help. I work for Ferbs Cosmetics: Tattoo Undercover temporary tattoo cover up cosmetics and currently Ferbs Cosmetics is also having a sale on temporary tattoo cover up kits during the 2009 holidays. Additionally you can order samples off of the website or if you prefer you can contact Ferbs Cosmetics directly for samples so you can try a full application of a shade or two before you buy a whole tube (or tattoo cover up kit.)
Tattoo Undercover is formulated specifically for temporary tattoo cover up and was developed by a tattooed licensed esthetican who specializes in custom cosmetics and tattoo removal. Tattoo Undercover is designed to have the flexibility and wear of foundation but the coverage of a concealer. Best of all Tattoo Undercover is completely waterproof and wont rub off! When comparing temporary tattoo cover up against the competition, Tattoo Undercover lasted an average of 3 days longer.
