The main active ingredient in here is lecithin (Phosphatidylcholine). Lecithin is the natural component of living cell membrane. Therefore it is readily aborbed by skin and is excellent for skin water reservoir. So this product is very moisturizing.
There is no clear definition for the ingredient neuropeptides. Dr. Perricone claimed that neuropeptides are peptides released by brain cells as intercellular messengers. While manipulating the neuropeptides, neurotransmitters and hormones that are in the brain to help slow the aging process.
However the reality is that the size of typical peptides are too large to be absorbed through skin pores and reach epidermis. Epidermis is the layer beneath the surface of skin (dermis) and it is where collagen and elastin proteins reside. If the peptides can't be delivered there, they are simply wasted. Besides they are at the bottom of the ingredient list, which means there are not a lot of them.
On the other hand the ingredient copper gluconate has been shown to increase superoxide dismutase (SOD) levels in humans which gurad against free radical damage. Copper may also help collagen synthesis and elastin.
The ingredient DMAE has only reported to prevent aging based on a small study by Dr.Perricone himself, the manufacturer of the brand. So the claims are not solidly supported.
This is a high quality eye cream. But I am conservative about the real effectiveness and neuropeptides and the steep price. For this I took away one half star.
