Im planning to look like the Joker for this years comic con (obviously its in october but its best to plan it now)

But I want to stand out by playing a dying Joker and well thats the problem, minus what shade of white powder or shade of red lip stick, anyone knows a good website that sells stuff to make my skin look like its coming off and that veins are going through my neck, like the picture below. Every suggestion will be appreciated

I´d suggest white makeup (liquid would probably be best)--easy enough to find at costume stores or at makeup counters as "goth white" makeup. Underneath the makeup, I´d put silicone (like the one they use to make sake scars and such) as a base to the face; making all those scars will take a while. Also, make sure that you have spirit glue as well to make it stick (though it might stick by itself--I´ve only ever used silicone ears, the scar silicone might stick itself). And spirit glue remover (to avoid unpleasantness when pulling the "scars" off).

So, basically:

1) Lots of silicone for fake scars

2) White face makeup as a base

3) Reddish skintone makeup (I´d actually go with matte eyeshadow powder; easier to find and handle) to do all those highlights around the scarring (and in the "lines" between) and give them that extra "real" look.

You´ll probably take hours, considering what his face looks like.....

EDIT: I completely missed the point there.....I actually bought my silicone ears on EBay, from a store that sells stuff for LARP. You might have some luck searching for that. Oh, and another friend of mine bought her liquid silicone stuff for when she cosplayed the Joker at a theater and costume supplies store. It´s a physical store, and it doesn´t have a website though. :/ Shame.

i can´t see the pictures sadly :( but i think i know what you are talking about though.

here is a good gothic website. you can probably find good  foundashion and powder here:  http://www.manicpanic.biz/store/c/38-Make-Up.aspx   you can find "gothic white" and and from pale to white powder here!   and a red lipstick here:   http://www.limecrimemakeup.com/categories/lipstick/  there is all coulers, both dark and light red lipstick! and i have 3 lipsticks from there and i love them so they have wonderful stuff! ;P

and for the veins i guess eye shadows..  and skin that falls off, maby wax/silicone (don´r reamember the name X( ) or those things you find in haloween make up kits.  i hade one and my pearents used it for a halloween party! (they were realy sceary) so you can really get realistic things whith that :P

anyway~ hoped it helped and good luck! :D
