Due to the obscure cylinder, the serum's in, you cannot see the amount contained. I imagined the product would last for 30 days, using a teardrop portion once daily, but a 14-day regiment was my limit using the Fresh Pressed Vitamin C .29 oz. Considering the quality and price points of Clinique products, my assumption was off by 17 days ( 31 days in December and January). I can't endorse the product because I didn't notice a noteworthy improvement to my skin after 14 days. No reorder for me.
