Multi-Peptide + Copper Peptides 1% Serum

The Ordinary Multi-Peptide + Copper Peptides 1% Serum — formerly known as "Buffet" + Copper Peptides 1% — is the brand's most comprehensive anti-aging serum. Five peptide technologies, multiple hyaluronic acids, amino acids and direct copper peptides in one lightweight layer, for people who want a single serum doing several jobs at once.

What it actually does

• Targets several signs of aging together. The Ordinary built this as a universal formula that helps soften fine and dynamic lines while supporting overall elasticity, smoothness and firmness.
• Copper peptides (GHK-Cu) — the brand says these support skin functions including collagen synthesis, fibroblast production, normal immune function and anti-inflammatory response, and also address aging signs linked to oxidative stress.
• Matrixyl works on the look of both static and dynamic wrinkles, while ARGIRELOX goes after fine lines, per the brand.
• The full roster: GHK-Cu, SYN-AKE, Matrixyl synthe'6, Matrixyl 3000, the ARGIRELOX peptide, hyaluronic acid, amino acids and bio-derivatives.
• Formula hygiene: free of sulfates, parabens, mineral oil, phthalates and the rest of the brand's exclusion list; vegan, cruelty-free and gluten-free.

How to use

1. Apply over the entire face, morning and evening, after cleansing.
2. Don't layer it in the same routine as vitamin C, direct acids or strong antioxidants — the brand recommends alternating between them (for example, this serum in one routine, your vitamin C in the other) to get the most from each.

Questions

Is this the same product as "Buffet" + Copper Peptides?

Yes — the brand renamed it. "Buffet" + Copper Peptides 1% is now sold as Multi-Peptide + Copper Peptides 1% Serum.

Why is this blue serum pricier than other The Ordinary serums?

It stacks five peptide technologies plus direct copper peptides, hyaluronic acids and amino acids in one formula — it's positioned as the all-in-one option in the brand's peptide range.

Can I use it with vitamin C?

Not in the same application. The brand advises alternating this serum with vitamin C, direct acids and strong antioxidants rather than layering them together.
