Used a salicylic acid acne pad too much/too long on an open pimple and resulted in burn. Please help! (Photo)

I had an open pimple & it was bleeding so I used my max complexion correction pads that I have for my acne & it kept bleeding anf ended up with this. It burns and the acid in the pads were obviously too strong and I wasn't suppose to use them that much. I'm freaking out and I'm putting neosporin and aloe vera right now but the redness hasn't gone away. The area around the white keepd getting darker is that suppose to happen? If anyone knows the best way to heal this wound comment I'm devasted :(
