Eye care · K-beauty dermocosmetic · medicube
A heavy-hitting peptide eye serum from a Korean clinical brand, priced like a mass-market product but formulated with a five-peptide complex and a full collagen and hyaluronic ladder. The listing's whole argument is clinical: six trials, a 20,000 ppm peptide load, and a texture light enough to sit under make-up.

01 Product information
Specifications as published on the listing, read in a US delivery context (New York 10001), so every figure is native USD.
What this product is
This is a 30 ml eye treatment sold as a serum. The listing positions it against puffiness, dark circles and the first fine lines, and explicitly allows use across the whole face, not just the orbital area. The format is a light emulsion rather than a watery gel: the INCI opens on water and methylpropanediol, then moves straight into cyclopentasiloxane and a C6-14 olefin, which is what gives it the primer-like slip buyers describe. Note the naming split — Amazon sells it as an Eye Serum, the tube itself is printed Deep Reviving Peptide Eye Cream, and the third-party ingredient record carries the cream name. One formula, three labels.
How it is meant to be used
Two pumps tapped around the orbital bone morning and night, then patted out over any expression lines. Because the base is silicone-and-ester rather than water-thin, it layers under sunscreen without pilling. The brand asks for a patch test first — worth heeding, since the formula carries fragrance and two fragrance allergens.
The listing's own claims
- Medicube Deep Reviving Peptide Eye Serum is a moisturizing eye serum that helps improve the appearance of puffy eyes and dark circles. Formulated with a high concentration of peptide complex, this eye serum is suitable for all four seasons and can be used on the eye area as well as all over the face.
- This eye serum has undergone six clinical trials and has been verified to be effective and unlikely to cause irritation. It is suitable for dry skin with premature signs of aging and dull skin with fine lines.
- Formulated with 20,000ppm of peptide complex, which has been independently developed by medicube through rigorous research. Peptides help to improve the appearance of puffy eyes and dark circles by providing moisture.
- Apply a small amount of eye serum to the eye area and gently pat until fully absorbed. Use morning and night for best results.
- Everyone has skin concerns. But not everyone finds the right solution. By working with dermatologists, we research the most effective formula and develop using the best ingredients.

03 What buyers say
Amazon's own review summary plus the aspect counts behind it. Individual review bodies sit behind a sign-in wall on this capture path, so the evidence here is the aggregate layer rather than quoted reviews.
Customers find this eye serum effective and moisturizing, noting it provides plenty of moisture around the eye area and has a non-greasy texture that feels like a makeup primer. They appreciate its value for money, with one customer noting it works twice as well as more expensive alternatives. The product improves skin appearance, making eyes look brighter and more refreshed, while reducing the appearance of fine lines around the eyes. Regarding skin irritation, while some customers report no issues, others mention experiencing burning sensations.

Comedogenic and irritancy levels
Each ingredient is placed in one of four levels using the worse of its comedogenic and irritancy grades. Rows the source leaves ungraded are kept in their own bucket rather than being read as zero — an unrated ingredient is unknown, not innocent.
| Level | Ingredients | Share | What it means in practice |
|---|---|---|---|
| Level 1 · no flag | 4 | 3.8% | No comedogenic or irritancy grade recorded against it. |
| Level 2 · low (1) | 3 | 2.9% | Grade 1 — generally tolerated, occasionally relevant on very congested skin. |
| Level 3 · moderate (2) | 5 | 4.8% | Grade 2 — a genuine consideration for acne-prone or reactive skin. |
| Level 4 · elevated (3+) | 3 | 2.9% | Grade 3 and above — the rows that drive the pore-clogging and irritation warnings. |
| Unrated | 90 | 85.7% | No grade published. Unknown rather than safe; the honest reading is 'not assessed'. |

What the numbers say
The only series carrying observations is 3rd Party New, currently $18.90 against an all-time average of $32.14. At $18.90 the offer sits -13.3% against the $21.80 list price. The tracked range runs from $14.79 to $72.16 — a $57.37 spread that says more about third-party volatility than about the brand's own pricing. Monitoring began Nov 24, 2021, and the last tracked observation predates this capture by 4 days ago.
06 Who it suits
Strong actives story, unusually transparent ingredient disclosure, and a price that undercuts the French pharmacy competition by roughly half. The trade-offs are real: fragrance, silicones, five flagged pore-clogging ingredients and an unrated-grade majority mean this is a formula for normal-to-dry skin that tolerates richness, not for reactive or fungal-acne-prone skin.
Buy it if
Normal to dry skin, first fine lines, anyone who wants a peptide eye product at a drugstore price, and buyers who wear eye make-up daily.
Skip it if
Fungal-acne-prone skin, rosacea-prone skin, anyone who reacts to fragrance, and buyers who want an oil-free or silicone-free eye product.
07 How this was assembled
| Block | Confidence | Basis |

| Price, availability, seller | High | Buy box read in a US delivery context; USD native, no conversion |
| Rating and star split | High | Rendered on the listing at capture time |
| Review sentiment and aspects | Medium | Amazon's aggregate summary and aspect counts; individual review bodies were behind a sign-in wall and are not quoted |
| Ingredient table (105 rows) | High on identity, medium on grades | Single full read of the ingredient record; grades are community aggregates, not a regulatory standard |
| Comedogenic / irritancy screening | Medium | Only the graded subset informs it; unrated rows are reported as unknown |
| Price history | High on transcription, medium on recency | Summary table transcribed verbatim; the current column is a last observation |
Capture date 2026-10-31. Prices, rank and rating are live values and move between captures; two runs a day apart on the same listing routinely disagree.
