Dear Dr Irwin I amm 44 with fair skin which freckles in the sun, oily t zone and wrinkles around eyes. In august i started to use obagi nu derm with great reluctance because of the hydroquinone. However i thought i would do the 18 wks then stop and go onto something else i am now being told i need to stay on it for life as my skin will return to its previous state and i could suffer hyperpigmentation. pigmentation was not a problem for me anyway i went on nuderm for wrinkling and sundamage and to refine the skin. i enjoy using the tretinoin but have been told it doesnt work if i dont use the blender with it. I just want to follow one of your regimes and have purchased tns already> please help. regards Jo
