Mary Kay sells a great concealer - I cant remember the name but it is the only one they sell that has a green tint to it..apply that first and then get a second concealer that will match your skin tone....
...do it after the last coat of protan has dried as it may "soak up" too much of the dye and leave a dark splotch...so after protan....you might want to try a spot on your arm with the concealor and with the protan on top of it as the Hot stuff can cause cosmetics to run....
