From Jouer's website, "This lightweight moisturizing tint evens out imperfections and fades the appearance of fine lines with its light-diffusing multi-mineral formula. SPF 20 protects from UVA and UVB rays while Ginseng and Gingko Biloba Leaf Extract deliver antioxidants to skin, promoting a healthy complexion. Light to Medium coverage."
A full-size version of this product is 50 ml or 1.7 fl oz. This is plenty for a few months of everyday use.
Overall I would give this product three stars. The sales person told me it would make me look "glowing from the inside" which, if you ask me, is a pretty tall order to fill. This ended up being true to the extent that it made me look like a human disco ball. The "shimmering tint" that they promise is not so much a shimmer as it is a full out face sparkle. I have found that the only time I can use this product is when I mix it with some CC cream. It gives me just a little bit of shine without being overly distracting and sparkly. I wouldn't recommend this for everyday use.
