I am interested in buying these products for my wife.

All the claims made about the product that I can find are made by the makers. Is there any independent assessment of cosmetic claims?
Those were some amazing claims which I’m not qualified to refute. What I suggest you do is google “Cosmetics Cop”. The woman who runs the website, Paula Begoun, reviews cosmetics and skin care products in a series of books titled “Don’t Go to the Cosmetics Counter without me” which are updated periodically. She’s given some very good advice. Hope this helps.
