Amazon.com: Obagi Professional C Serum 20%, Vitamin C Facial Serum with Concentrated 20% L Ascorbic Acid for Normal to Oily Skin, 1.0 Fl Oz Pack of 1 Product Name : Beauty & Personal Care

I have very sensitive, fair skin. I also have spent most of my life outdoors for work and play. Needless to say, my skin reflects my activities. I purchased this serum after talking to a dermatologist. She explained that the Vt C will help to break up the brown spot pigment and will help improve the hydration of my skin. I couldn’t ever seem to find any product that would “sink into” my skin. This one does the trick! And, typically things bother my eczema-prone skin, and I have the added complexity of things breaking out my sensitive skin. But I have been so impressed with this serum because I am seeing nothing but positive results. My skin looks and feels softer and healthier. I would and do recommend this to my friends. And I will be purchasing it again when I run out. The price is up there, but a little goes a long way, so it should last you several months, making it well worth the investment, in my opinion!
