How to remove a set foundation stain?

-I accidentally spilt some liquid foundation on one of my favourite shirts and thinking it would just come off put in in the wash. Turns out I was wrong and all I did was set the stain, I didn't heat dry though I air dried. Does anyone know anyway to get it out using products I can get in the UK? This is the top if anyone needs to see what it looks like and the stain is on one of the white stripes:

Sometimes a soft toothbrush will help then SOAK w/ the next load of clothing... If that doesn't work it might be set in for good !vanish stain and upholstery remover.
