What the gurus are saying
At 3% copper peptides (higher than most alternatives, which typically max out at 2%), this serum won over reviewers enough to prompt repeat purchases. The formula turns a distinctive bright blue when applied, though that's purely cosmetic and fades once it soaks in. At $45-50 per ounce for 3% copper peptides plus additional peptide complexes, reviewers felt they were getting good value.
