Sally Hansen Face hair removal burned the corner of my lips?

So I use this product when I don't have time to go get my upper lip waxed. It's never given me trouble before.

I used it the other morning at around 330 ( I had an early shift at work ) and I guess since I was so tired I didn't notice it fall on the corner of my lips and now the skin is super dry/chapped there. It almost feels a little burned.

It looks gross, but not like a cold sore. And hurts when I open my mouth wide.

I put aloe on it last night and throughout today with little to no relief.

What can I do to make it go away? It's a constant nuisance.
