To effectively use Vitamin C Eye Serum for tired eyes and dark circles, pat a small amount under the eyes and lids using your ring finger (the weakest finger) until cream disappears. May be used both morning or night, by itself or under a heavier eye cream for a brightening boost. This is a professional product so a little goes a long way.
Note: Vitamin C Eye Serum comes in a special airless container. The pump should never be opened as it will introduce air into the bottle causing the product to not pump out properly. When you first recieve the product, you may have to pump 5-10 times on the first use to get any air out of the bottle.
