I have thickened skin on my cheeks 1.5 years after spot dermabrasion. I feel that the doctor went too deep, because the area is hypopigmented as well. I'm working on the hypopigmentation by using a derma roller .5mm to hopefully transplant some melanocytes to the affected area but am at a loss for the thickened, scarred skin. I'm seeing a new dermatologist who prescribed me Retin-A and said its the only way to cure the scarred texture but how do I reduce the raised, thicker skin ? Pls help.
