A seven-ingredient Korean ampoule built on Madagascar centella, checked against its claim sheet, its full INCI and its tracked price history.
Torriden's five-weight hyaluronic acid serum, checked claim by claim: a clean fragrance-free sheet, 36 ingredients and a tracked price curve.
A 30 ml Korean peptide eye serum with 105 declared ingredients, six clinical trials behind it and a fragrance flag to weigh. Full INCI, claim sheet and tracked price history.
The cleanest star distribution in this batch hides a single aspect that splits two to one against the product. Twenty-five ingredients, a WON'T CLOG PORES stamp and a regional caveat that governs the whole formula section.
Five ceramides, a milky texture and no fragrance - the sensitive-skin promise holds. But an emollient third in the list is flagged as comedogenic, and the pack prints Non-comedogenic anyway. What 20 ingredients, 3,712 ratings and four years of prices add up to.
A stabilised vitamin C salt leads, pure L-ascorbic acid follows, and six fruit extracts pad the middle. What the 35-row formula, 8,435 ratings and six years of price records say about a serum that costs less than half the clinical end of the category.
The formula formerly sold as Buffet - five peptide technologies, a full amino-acid pool and hyaluronic acid - currently priced at its own all-time high on both channels.
An EGF-and-13-peptide ampoule with 24K gold, dosed through a syringe applicator, carrying 966 ratings and a seven-month price record that fell 34.5% before recovering.
A five-technology peptide serum with GHK-Cu at a declared 1%, 49 ingredients, 3,817 ratings and a price that has not moved off the top of its own band.
A ten-ingredient Korean hydrating serum that stakes its whole proposition on beta-glucan and on having almost nothing else in the bottle, sold at a street price that has barely moved from its own long-run average.
EQQUALBERRY puts fourteen peptides, five ceramides, eight hyaluronates, NAD+ and NMN in one 30 ml bottle and sells it at $21.99. The formula is genuinely unusual. The reviews are not: hydration is praised, irritation and price are the two things that break it.
A temporary silicate-film eye serum that divides buyers. We break down the 14-ingredient INCI panel, the polarized 4.0-star rating from 12,372 reviews, and the third-party-only price history.
