Cora reviewed The Ordinary's Buffet + Copper Peptides 1% and found it to be a game changer for glassy skin and anti-aging benefits. Cora replaced their vitamin C serum with the copper peptides and noticed a difference in their skin's glow. The peptide helps the skin produce more collagen and helps with signs of wrinkles. Cora has reordered the product multiple times and highly recommends it.
