Water proof concealer?

[BoSox]

I've been using Dermmach, and it works great for hiding my thinning. They claim it's water proof, but every time I get out of the shower the next morning, it is mostly off... I'm going canoeing tomorrow... is there any products out there that are completely water proof?

Depends on if you are rubbing it or not but not sure with Dermatch.

Prothik is fairly waterproof...............have gone swimming and been out in the rain...................not a problem.................unless you start rubbing it.
