One of my nearest and dearest friends Anne-Marie swears by Obagi Professional-C Serum 20%. I can see why. It is truly fantastic. After two days, my skin shows active positive development. This Vitamin C Serum comes in 5%, 10%, basically weaker variations – just go for the full 20%. It is pricey, so you might as well get a product with punch. I’ll keep you posted on the on-going results.
