Excellent Vitamin C Serum!
I have been using this product for a few weeks now and am very happy with the results!  My fine lines have softened and the dark spots are less noticeable.  My skin feels silky and smooth.  This product has the maximum recommended 20% Vitamin C, which is known to help produce collagen and is a potent antioxidant. It really does work!
