This is a very interesting article (click on the link below), which highlights the things that Dr. Obagi has been saying for years. We are trying to normalize the skin’s function, not just “cover up” things on your skin. Prescription-strength tretinoins and very strong retinols are doing the work of improving your skin. Bleachers help lighten pigment. These are the basis of ZO and OBAGI skin care, and all you have to do is use the products to see the difference in your own skin!
