I've heard about the Obagi Nu-Derm System -- mainly for removing skin discolouration. Do you use it all the time? I understand they have a complete line of products including moisturizers. Why did you start using it? Perhaps the product line is too strong to be used continuously. If the product has a contact number or web site I'd let them know your concerns. If you still want to use their product because of the results, I'd introduce a light serum or cream to offset your symtoms.
