I started using the Aldi 5% glycolic acid toner at weekend and now have 5 big red sore spots on my face. Is this my skin getting rid of all the crap and it will clear up soon, or shall I stop because it doesn't agree with my skin?? First time using anything like this so not sure. Or c) is it cheap crap? The nip + fab glycolic pads have brilliant reviews but don't want to try if it's the acid causing the spots.
