This is my second week into using Skinceuticals Retinol 1.0.
My approach (which was ver zealous one) was to use it every night before bed for 2 weeks straight.
Please do not ask me why I came up with that idea...and yes, I realize the approached was idiotic.
I made it to 5 nights and had (of course) a reaction that was seemingly "severe" in that I had tiny blisters on my neck and what...
