70% Glycolic Acid Peel with Mild Psoriasis on Face

I am a 32 year old male with mild psoriasis on my forehead just below hairline and two small areas on cheeks. It is well controlled with steroid creams. I have purchased a package of six 70% vivite glycolic acid peels(only offer 70%) and six microdermabrashion treatments. I just had my first demabrashion with no side affects. What sequence would you suggest as far as treatment beetween the peels and dermabrasion and steroid cream?
