I am in my late 40's & have dark-tan/olive skin. Can I get a blue peel with out EXTRA hyperpigmentation to the skin. My purpose is to tighten skin, decrease fine wrinkles, and get rid of face blotchiness and slight hyperpigmentation to my skin. I have to be careful with my skin as it can hyperpigment easily. Are there alternatives to the Obagi Blue Peel, or something even better for dark-tan-olive type skin.
