Best peptide serums

Peptides sit at the gentler end of the actives shelf, and the category is crowded with vague blends and fairy-dusted claims. We score each peptide serum on evidence, dose disclosure, and formulation with the same SerumProof rubric, then rank by total score. The picks below run from highest to lowest.

   Zero Pore One-Day Serum

   A well-priced, mostly gentle PHA-led exfoliant with a genuinely disclosed total acid percentage and a sensible 2% niacinamide alongside it. The headline "10-peptide" and copper-peptide story is the weakest part of the label, an undosed marketing add-on rather than a real second active. Buy it for the acid blend, not the peptide claim.

   $26, ~$8/mo

   Purito Seoul

   Centella Green Level Buffet Serum

   A genuinely high-percentage centella serum at an easy price, and the headline claim holds up on the label. The niacinamide addition is sensible if underdosed, and the peptide quartet is dressing more than a real second active. Judge it as a strong, well-priced soothing serum, not a multi-tasking peptide treatment.

   $18, ~$5/mo
3. 371
   The Ordinary

   Multi-Peptide + HA Serum

   A broad peptide serum for around fifteen dollars, with hydration built in. The catch is disclosure: none of the peptide levels are stated, so you take the doses on trust. As a low-cost, low-risk entry into peptides, it is still good value.

   $19.9, ~$12/mo
4. 467
   Isntree

   TW-Real Bifida Ampoule

   A concentrated, well-priced fermented ampoule that leads with a genuinely high, brand-disclosed bifida ferment lysate dose and a solid niacinamide showing. The GHK-Cu and Argireline on the label read as marketing dressing: both sit below the 1% line based on list position, so do not buy this expecting a real peptide-serum result. As a barrier-focused fermented hydrator, it holds up fine.

   $26, ~$9/mo
5. 562
   The Ordinary

   Multi-Peptide + Copper Peptides 1% Serum

   The value benchmark of the category: multiple studied peptides at a disclosed copper level for roughly the price of a lunch. It is the obvious first serum to compare everything else against, even if you re-cap it fast.

   $32, ~$19/mo
6. 660
   SkinMedica

   TNS Advanced+ Serum

   The packaging is excellent and the price matches it. The growth-factor evidence is real but modest and largely brand-led, and on proven actives per dollar it is very hard to justify over options a tenth of the cost. You are paying for the science story and the bottle.

   $295, ~$187/mo
7. 760
   Medik8

   Liquid Peptides

   A polished, comfortable peptide serum from a serious brand, but the evidence and the pricing do not line up. The headline peptides carry limited support, the doses are undisclosed, and you pay a lot for the count on the label. Pleasant to use, hard to justify over cheaper multi-peptide options.

   $68, ~$41/mo
8. 856
   Augustinus Bader

   The Serum

   An expensive serum that asks you to buy a proprietary complex on faith while its disclosed actives are present at supporting levels. The ingredients that are named are fine and well-tolerated, but nothing here justifies the price on evidence. You are paying for the brand story and the texture.

   $405, ~$243/mo
