How long will this healing process take for my skin to go back to normal?

I burnt my skin using a hair removal facial cream and it's been 3 weeks now and the scab has came off and now it's just the pink skin and it's been exactly the same for 3 weeks now, two days ago I developed these red little bumps they're not itchy but I think it's dermatitis? I have a doctors appointment tomorrow but I'm concerned. I have aloe vera smeared all over my face to help reduce the redness. I just want to know how long it'll take to heal and also if those red bumps are dermatitis? Thank you.
