The Buffet + Copper Peptides 1% is a skincare serum that combines multiple peptide technologies with copper peptides. Peptides can help improve the appearance of fine lines, wrinkles, and skin texture, while copper peptides have been shown to have antioxidant and skin-repairing properties. However, it's important to note that individual results may vary, and some users may find the texture or formulation of the serum less suitable for their skin type.
