hmm i'm a lil late but try 'covermark leg and body magic' it's a type of camouflage makeup, that completely conceals 'scars, tatoos etc'...it lasts for 24 hours n it doesn't smudge once dried...(only takes a couple of mins.) Just make sure you get the right colour...so it blends in properly! So you might have to buy a tester pack with all the shades in it 1st...
Beats long sleeves, annoying accessories n paranoia anyday!
Or does it play no part?
