The most recent postings can be found in the Anti-aging section under the "Hydrating Serums" thread, esp. #103-106. (Sorry, I cannot get the link to work tonight).
If you read through the site you will find other variations of it, but this is one that is easy to start with.
You can also use the "Search" function on the site to find more discussion of the serum. You are right, it shows up all over the place - I suppose because it is an interesting topic here right now.
