The Ordinary Buffet + Copper Peptides 1%

probably the best 1% copper peptide for the price, copper peptide is not cheap, so if you see a really cheap copper peptide product, look at it's position in the ingredients list. your lucky if yo get even a tenth of 1%. The only cheaper way is to make your own, copper peptide powder is available even here on walmart.

I like this serum. I think I expected more than what it does though. It is good though. I will see what I really thi k after 30 days of use.
