I was intrigued with this serum when I first saw the specs and great reviews on this product. Although pricey, I took the plunge and ordered it on subscription. Since using it twice a day for 3 weeks I have found that it gives my complexion a glow, has reduced some fine lines and wrinkles, and has rather dramatically decreased areas of pigmentation on my face. This is a win for me and I will continue to purchase this serum for the forseeeable future.
