You poor thing. Ok so haven't tried this myself but have a friend who is a make up artist and she suggested either lemon juice, but be careful if you have cuts or sensitive skin as it can be strong and very astringent. Alternatively, if you rub in whitening toothpaste (got to be the whitening kind) then wash it off, that may also work. There are corrective wipes you can get but think they are a bit costly. If none of those work, using an exfoliating glove on the worst parts should help but prob not take it off.
