I Used Nair Hair Removal Cream On My Face And

I used Nair hair removal cream on my face and I guess I left it on a tiny bit too long and my skin started irritating and burning and slowly on my chin, the guess the top layer of my skin sort of burned off? The burn is like half a centimetre long and there are other smaller spots of burn that are like less than half a centimetre long. I think it was a milk burning and luckily it was only on the right side of my chin, 3 spots on my cheek. I am worried whether they will scar my skin [since I have always been accustomed to clear and clean skin] and also i am anxious on how long it will take to heal or whether it will heal or not and if it will leave an ugly scar forever. My burn is quite mild but it is sort of like the top layer burned off? And also how can i tell whether my burn is healing? Thanks
