Peter Thomas Roth Peptide 21 Wrinkle Resist Serum: I was very anxious to try this because of all those different peptides - 73%! I mean, wow! Thats a lot of peptides, and at 58, I need all the help I can get! I am very satisfied with the product. I use it in the morning after my Vit C and at night, I mix it in my tretinoin cream. My skin is more hydrated and radiant but with no breakouts, which I get sometimes because I have combo skin, normal to dry in some places, oily around nose and chin. I will definitely buy again.
