Thanks. I also have another question.
I read on a product site (that I no longer frequent) that that I should not use copper-peptides and vitamin C together or within 12 hours of each other because vitamin C inactivates itself when used with a peptide. I don't really trust information from that site to be correct anymore. Before I did my own research and aware of the companies false claims, I purchased products that were ineffective and expensive. In fact, there was a post on this forum that led me to question the effectiveness of the product that I had purchased. Then, after using it for months, it reaffirmed that the company mislead me.
I was so tired of being tricked that I started creating and researching to make my own cream/serum (only for my personal use). Last night, I combined 5% Tripeptide-5, 10% Vitamin C, 5% Niacinamide, 5% Licorice Extract, 4% Retinol, 5% Green Tea Extract, 5% Alpha Arbutin, and the remainder was water. I remember today that I read that I shouldn't mix/apply vitamin c and peptides together, which is the reason for my first post on this forum. I accidently mixed up the question regarding vitamin A, but it should have been about peptide because I forgot about it. I only remember that Vitamin C clashed with a ingredient, but I couldn't remember which ingredient, so, I thought it was Vitamin A. Could peptide and vitamin C be combined together?
