i get the impression that you need something that is full coverage. why dont you try http://sephora.com/browse/product.jhtml?id=P151107
Here are some heavy duty concealers that might get the job done:
Benefit Boi-ing: Great coverage but comes in only light, medium and dark.
Makeup Forever Full Coverage: Again great coverage and also waterproof. (Make sure to find the correct shade or else it won't act as "full coverage" - I was mismatched a few times and wasn't happy with the result.)
Kat Von D Tattoo Concealer: If it covers tattoos, I'm sure it can cover broken blood vessels. Also water resistant.
Amazing Cosmetics Amazing Concealer: The brand basically specializes in perfect concealing. Pricey but also comes in smaller travel size.
Hope these help and good luck!
