Quick Verdict
Best for: people wanting a peptide-based firming serum without retinol’s irritation risk. Skip it if: you want dramatic, fast results — peptides work gradually over months.
What Is This Serum?
“Buffet” is The Ordinary’s flagship multi-peptide serum, combining several peptide complexes and hyaluronic acid into one formula aimed at addressing multiple signs of aging at once — fine lines, loss of firmness, and dehydration. The Copper Peptides version adds copper tripeptide, associated with supporting skin repair processes.
Key Ingredients
- Multiple peptide complexes — signal skin to support its own collagen and elastin production
- Copper Tripeptide-1 — associated with wound-healing and skin repair research
- Hyaluronic acid — adds hydration support

Who This Is Probably a Good Fit For
A good fit for people who want to start an anti-aging routine but can’t tolerate retinol, or want to add a gentler complementary product alongside one. Peptides work through a different, slower mechanism than retinoids, so patience is part of the deal here.
Pros and Cons
What We Like
- Very low irritation risk compared to retinol
- Affordable for a multi-peptide formula
- Can be used morning and night, and during pregnancy (unlike retinol)
Worth Knowing
- Results are gradual — expect months, not weeks
- Copper peptides can oxidize/discolor if mixed improperly with certain other actives
Frequently Asked Questions
How long before you’d see results?
Peptides work gradually by supporting the skin’s own repair processes, so most people report noticing firmness changes after 8-12 weeks of consistent use, not days or weeks.
Can you use it with vitamin C or retinol?
Copper peptides and vitamin C can interact and reduce each other’s effectiveness, so The Ordinary recommends using them at different times of day (or on alternating days) rather than layering directly.
