I Was Waxing My Upper Lip Yesterday With Ready To

I was waxing my upper lip yesterday with ready to use wax strips, and the area became very red and painful afterwards, more so than usual, so I applied cold water and aloe Vera gel, but when I woke up this morning the redness had become these dark brown, dry patches. They are incredibly noticeable on my pale face. How can I treat this to make the dark patches go away? Is this going to leave scarring on my face?
Thank you
