Here's the deal with Obagi...it is a fabulous product. It is also however, extremely strong and can be harsh and damaging to the skin. That being said...I believe it is more of a reparative skincare product then a maintenance skincare product. If you are past the point of preventive and have entered the world of reparative, Obagi is a good place to start. If you do decide to go with an Obagi regime, pick a 6 month program (they have different options) finish the program then stop! Being an Esthetician I have seen quite a few people who have been on a Obagi regime for extended periods of time and their skin looks transparent! After you have finished your 6 month regime and have repaired the skin it is up to you to maintain it. I suggest using an "At Home" Pharmaceutical Grade Chemical Peel! Glycolic Acid along with high quality professional skincare products, will not only save you money, it will also save your skin! Try SkinRxClinic's "At Home" Glycolic Acid Peel. If you are looking for a way to kick your skin into high gear this is another option for you. It is worth looking into go to www.SkinRxClinic.com type "glycolic" in the search box the product and all the information will come up!
