I am ever so thankful you took the time to write this in answer to my
query. I joined this list because most forums don't get into such
"technical" discussions and I know just enough chemistry to get in my
own way. I've read Angie's site from end to end and have purchased
several of the products you mention (among lots of other things!). It
is this interest that spurred my initial post. Before submitting here,
however, I scoured the internet for several days, but could find
nothing that defined the class of "cosmeceutical" peptides as eloquently
or succinctly as you have here for us.
Again, I am most appreciative, Cindy, and will look forward to reading
your blog on your website. Which, btw, has also been most helpful to me.
Most kindly,
---Susan Snowden
