This serum comes in a 1 oz dropper bottle. I was very excited to use this product since Dr. Oz recommends use of vitamin C serum for a variety of age-defying benefits. This product spreads smoothly and it absorbs well into the skin. I love how it is not tested on animals. After using it seemed to brighten my skin. I would recommend this to anyone. You can buy this on Amazon for $14.50.
