11 serums, scored
- $26medicubeZero 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.
- $18Purito SeoulCentella 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.
- $19.9The OrdinaryMulti-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.
- $26IsntreeTW-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.
- $32The OrdinaryMulti-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.
- $295SkinMedicaTNS 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.
- $68Medik8Liquid 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.
- $405Augustinus BaderThe 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.
- $179BioEffectEGF Serum
An elegant hydrator wrapped around a preliminary-evidence growth factor at a prestige price. The HA base delivers the appearance of hydration reliably; the EGF story is early, undosed and hard to protect in a dropper. You are buying the science pitch, not settled results.
- $62Paula's ChoicePro-Collagen Multi-Peptide Booster
A solid mid-tier pick with a broad peptide lineup. You pay a premium over the budget benchmark for formulation polish rather than for more proven actives.
- $258Plated Skin ScienceINTENSE Serum
The packaging respects how delicate the active is, and the underlying idea is interesting. The problem is the evidence: exosome skincare is preliminary, there is no studied use level, and the price is firmly prestige. Promising to watch, hard to recommend at this cost today.
