I took a quick look at this but it will be a few weeks before I can post something to the blog. The bottom line appears to be that the active ingredient (which is based on salmon eggs) does have properties similar to AHAs or retinol. It has to be used at 1% to get the effect and I can't tell if the Restorsea product contains that much or not.
Also, while the ingredient works like an AHA/retinol I don't see any data to show that it works BETTER than those ingredients. So I don't know any reason to spend more on this product ($150/1.7 ounces) when you can get an AHA/Retinol product for much less.
