01Product information

Koriderm positions this as the whole routine in a single tube: cleanse-and-tone, then one cream that is supposed to hydrate, firm, calm redness and soften expression lines at once. The ingredient count is deliberately small - eighteen entries, with a centella extract as the lead active and a single peptide carrying the anti-aging story. Nothing in the formula is novel. What is unusual is the ratio of claim to actives.

The commercial read is straightforward. The unit price of $29.53 an ounce puts it at the top of the moisturizer tier, the rating base of 771 is large enough to be meaningful, and the price record shows a step up from a launch discount rather than a promotional cycle. It is a product priced on positioning, bought on texture, and reviewed on hydration.

What the listing promises

02Rating and customer voice

Two things are worth separating here: the shape of the star distribution, and the words buyers use when they explain it. The first is arithmetic, the second is evidence. Neither is extrapolated past what the listing published.

What buyers say, in aggregate

Aspect-level sentiment

A high positive share on a small mention count is weaker evidence than a middling share on a large one. Read the two columns together.

Customer voice

Verbatim review text did not render on the captured listing page, so none is quoted. The aggregate summary and the aspect table above are the published substitutes; no review language has been written on the product's behalf.

03Ingredients

18 ingredients were merged into a single roster and graded on three axes: comedogenic risk, irritation risk and an overall safety grade. On all three, low is safer. The level assigned to an ingredient is the highest of its three grades, so one severe flag is never averaged away by two benign ones.

What's inside

A "not" prefix is a failed claim, not a marketing variant: the formula does not meet that standard.

Level classification

"Not graded" means missing data, not a clean record. Commodity ingredients and botanical blends routinely carry no grade in either database.

Benefit claims and the size of the supporting cast

Class-level concerns

These are class-level warnings: the formula contains ingredients capable of the stated effect. They are not a prediction about any individual user.

Key ingredient groups

• Centella Asiatica Extract — 1 ingredient(s). Position 2 and the lead active. Its four triterpenoid saponins - asiaticoside, madecassoside, asiatic acid and madecassic acid - are the most researched part of this formula and the only ingredient here with decades of literature.
• Acetyl Hexapeptide-8 — 1 ingredient(s). Position 18, the last ingredient in the declaration. Known as Argireline, positioned against expression lines. Its placement matters: it is present at the lowest concentration in the formula.
• Sodium Hyaluronate — 1 ingredient(s). Position 6. The salt form of hyaluronic acid, lower molecular weight than the acid itself. Carries the plumping claim and is the most corroborated ingredient in the roster.
• Ectoin — 1 ingredient(s). Position 8. An osmolyte that protects against environmental stress and water loss. The second named active in the brand's own positioning.
• Oat Bran Extract — 1 ingredient(s). Position 14. Recorded as an abrasive rather than a chemical exfoliant, so the 'exfoliator' grouping rests on mechanical texture smoothing, not on an AHA or BHA.

04Price and history

Every figure is native USD against a U.S. delivery address. No currency conversion and no estimated value has been inserted. The history block covers the full monitoring record rather than a rolling window.

Price history

"Current" here is the last observed value with its own date stamp, not a live quote. Monitoring began August 2026, roughly three months of record.

06Data notes

• Verbatim review text and customer photographs did not render on the captured listing page. No review language has been written on the product's behalf; the aggregate summary and aspect table are the published substitutes.
• The product has no rating on the ingredient database either - zero ratings, zero written reviews - so no third-party quality signal exists for cross-checking the 4.1 Amazon score.
• Price history covers a single channel. No Amazon-fulfilled and no used-market history was recorded during the monitoring window, so the figures describe third-party seller pricing alone.
• The tracker's current value and the live listing agreed exactly at capture, so no reconciliation was needed between the two.
• The brand is recorded as American while the listing positions the product as formulated in Korea. Both can hold at once - a U.S. commercial entity selling a Korean-developed formula - and neither is treated here as a contradiction.
• Best sellers rank and price are snapshot values. Rank in particular moves daily and should not be read as a stable position.
• Ratings, prices and sales ranks move between captures; every figure here describes the snapshot date only.
• Ingredient grades are community-database aggregates used as a reference, not a regulatory or dermatological verdict. Formulas are reformulated without notice and the carton is the authoritative text.
• No reviewer name, handle, profile link or other identifier appears anywhere in this report.
