chemical burn , how do i get rid of it?!

i burnt myself with deodorant ( i sprayed it on my hand to see what i smelt like ) i know im a total freaking idiot but oh well , i wont do it again so ive learned my lesson

so now i have this red hardish lump thing that is wrinkly , i thought it was a blister but it is defiantly not , it a lil sore since i did it a few days ago, but i wanna get rid on this ugly mark

please don't post silly answers , ive already know how stupid it was but i didn't realize it would burn me, and i wont do it again
