I am in my early forties & have been suffering with adult acne & oiliness, however that is a thing of the past with this blemish +age Defense treatment. I also believe that this treatment has had a positive impact on my fine lines & skin clarity. I will definitely look at trying other products in this awesome Skin Ceutical range. These are really potent products filled with high quality ingredients. The Blemish + Age Defense formula contains Dioic acid, Lipo Hydroxy acid, Saliccyclic Acid, Gloycloic acid & Citric Acid, so I can understand why my skin has been improving & looking
clearer. It does not come cheap at you will probably only find at an exclusive salon.
