I used it for about 6 months building up tolerance slowly, slowly, but got fed up with dry skin patches all the time.
I stopped in August and last week I caught myself in the mirror and my pores looked dirty and my skin was dull.
So I brought out the tret and used it 4 days in a row. My skin was sore by day 3 but I did one more day.
A few days of moisturising after I had stopped and my face looks good without the dry patches that I know I would still have if I carried on.
So basically is it OK to use tret as a skin peel every now and again?
