The Ordinary Buffet

Excellent ingredient-list position at a fraction of the price. All seven peptide technologies sit at positions 4 through 10 — ahead of the hyaluronic acid, far ahead of the preservatives. That is the same structural signal Medik8's $62 serum gives you, for around $17.

The Ordinary partially discloses concentrations, which almost nobody in this category does.

The supporting base is genuinely good — multiple hyaluronic acid weights, 17 amino acids, and a natural-moisturizing-factor complex. Even setting the peptides aside, this hydrates well.

Peptides are the most oversold category in skincare, and this is the honest picture.

A 2026 systematic review in Frontiers in Medicine pooled 19 randomized trials of peptides. Only two of them tested topical peptides — the rest tested oral collagen supplements. And the wrinkle benefit the review found was driven almost entirely by the oral studies, not the topical ones. Elasticity showed no meaningful effect at all.

There is also a physical problem. Peptides are large molecules, and the skin barrier is very good at keeping large molecules out. Independent reviews of the penetration data are blunt about it: most topical peptides concentrate in the outermost dead layer of skin and drop off sharply below that — nowhere near the depth where collagen is actually made.

And most of the foundational research comes from the companies that sell the peptides — Sederma, Lipotec — rather than from independent labs.

None of this means peptides do nothing. They are gentle, they are well tolerated, and there is a real argument for them in skin that cannot handle retinoids. But be clear on the comparison: retinoids have decades of large, independent, randomized evidence for wrinkles and photoaging. Peptides do not. Gentler, yes. Equally proven, no — not close.

Seven peptides share one formulation budget. More is not better — spreading the same amount of active across seven technologies means none of them is present at a high individual dose. "Kitchen sink" is a fair description.

The evidence problem is not solved by the price. A cheap peptide serum and an expensive one rest on the same thin foundation.

Confusing rebrand. "Buffet" is now sold as "Multi-Peptide + HA Serum." Same formula, different name.

If you can tolerate a retinoid, use a retinoid. The evidence is not comparable, and a $10 retinol will do more for wrinkles than any peptide serum on this list.

Formulation Notes

The 17-amino-acid and NMF complex in here is quietly the most reliable part of the formula — those are humectants and they demonstrably hydrate. The immediate "my skin looks better" effect from a peptide serum is usually this, not the peptides.

That is worth naming plainly. A well-hydrated face has softer-looking lines within minutes. That effect is real, immediate, and has nothing to do with collagen.
