I accidentally combined microdermabrasion with retinol .5.

I accidentally combined microdermabrasion with retinol .5. Now my skin is red, burning, and peeling, but no open wounds.
I am worried I have permanently harmed my skin, have I? Will I scar?

What it sounds like you are experiencing is called a “retinol reaction”. It is normal for skin to react this way when having undergone a form of resurfacing from the microdermabrasion followed by the topical application of a retinoid. The removal of skin debris has allowed for deeper penetration of the retinol and the itching, redness and peeling is an indication the retinol is working. It can take a few days to clear up and the skin will return to normal.
