Has anyone else added The Peptide Serum to their regimen and been blow away by the results? I’ve used tretinoin for a long time and love it, but I think this Peptide Serum has taken my skin to the next level. I am horrible about taking before and after pictures. But I frequently go to a particular med spa for facials and treatments like neurotoxins (Daxxify is my favorite), filler, and Ulthera. At my last Ulthera brow lift treatment 2 weeks ago, the Nurse Practitioner said that I’ve always had pretty good skin but that it looks amazing lately and asked what I had changed. I told her I started The Peptide Serum a while back and didn’t know if it was we helping. She said that she can tell the difference big time. Anyone else having luck with it? The 3% GHK-Cu concentration is just miles above everything else in the market. And all of the other actives they add to it are just bonus and make it an excellent value for the money.
