before & after pictures are tricky to judge if you don´t see the whole face. In some pics I´ve seen in magazine ads, you sometimes only the crow´s feet area, which looks way more wrinkly if you squint your eyes slighty (which you can´t see in the pictures because they don´t show the eyes well enough!)- and in the after picture the eyes are relaxed and less wrinkly. I see they also do that on the website you mentioned.
Which doesn´t mean that the products don´t work, but they probably don´t work as well as they are portrayed IMO.
I googled the stuff you mentioned, and I found out that the gorgeous peel is a TCA peel (between 10 and 20%), and the serum is apparently a peptide serum. A peel of this strength (btw, why don´t they list the exact strength?) would be too strong for once weekly use I think!
