Hello :)

So one day i got a pimple on my forehead and i put Airol 0.05% cream for two nights so i can get rid of the pimple. The people dissapeared in 2-3 days but i got a white mark on my forehead that didnt go away ever..

Two days ago , i decided to start Airol treatment for its benefits...I put one night and i left it overnight.

The day after my face was fine and i didnt peel at all and i didnt have any side effects ...The next day though i realised a white spot that looks abit as a wrinkle from the side but its a white spot from the front..I got this spot above my upper lip.. Does anyone know what can i do about it and what it is ?  Thank you in advance <3
