Anti-Aging Cream with AC-11®, VITAMIN B12, and PROGELINE http://www.amztk.com/swissvita-anti-aging I got to try this skin serum, I have being using it for more than a week, and love how nourished my skin feels. A little goes a long way, just apply a small amount like a pea size and you can cover your face and neck. Love the cooling sensation when applied and how quickly it is absorbed by the skin. This is a very gentle serum perfect for sensitive skin. Love that it has no additives, that is paraben free, alcohol free, fragrance free and pigment free. This makes a great difference if you have dry and dull skin. Note: I received this product free or highly discounted for review and an honest and unbiased opinion.
