have used many Obagi products in the past but this is my first time to try this therapeutic moisturizer.  I chose this product because during harsh winter is the midwest I I live in Chicago), it is very important to keep skin moisturized and protected.  So let me explain why four starts for the product:  this 1.7 oz of product contains Glycerin 20% (skin protectant) as an active ingredient. Inactive ingredients include:  allantoin, corn starch modified and a wide variety of parabens.  That's right - it is when I see parabens on the ingredients list that I get turned off for a moment. I generally try to avoid parabens in any form whenever possible.
