I work with Ferbs Cosmetics and wanted to recommend Tattoo Undercover temporary tattoo cover up. It has to do with the way the minerals reflect the light that enables the cosmetic to do such a great job at covering vibrant tattoo pigments. The make up is much thicker than an average concealer which also allows it to dry faster with less applications.
The tattoo cover up is waterproof and available in 5 skin tones and we usually gives away free samples if you become a fan of our page on facebook at www.facebook.com/ferbscosmetics or just reach out and ask.
You can watch a demo video of the tattoo cover up process on their website or here is a few links from there website that offer help and advice on covering a tattoo:
