At a glance

How the ratings break down

Amazon's own star distribution for this product, read on 2026-10-28. We show the one-star share too, because an average alone hides it.

6% of these ratings are one or two stars. That is about typical for the Medicube range, where the median is 6%.

We cannot tell you what those reviewers said. Amazon.com now requires an account to open the full review list, so the critical reviews are not readable from a public page. We would rather say that than guess.

What are peptides?

Peptides are short chains of amino acids that signal the skin to look firmer and more resilient.

What the ingredient order actually tells you

• The peptide claim holds up on position. Five peptides sit together near the top, 11th to 15th of 105: acetyl hexapeptide-1, palmitoyl tripeptide-5, acetyl dipeptide-1 cetyl ester, acetyl octapeptide-3 and copper tripeptide-1. On a 105-entry list that is an unusually prominent peptide block, consistent with the 20,000 ppm (2%) the listing states.
• Ahead of them are panthenol ninth and niacinamide tenth, with a silicone at fourth giving the slip an eye product needs. Shea butter at 18th and meadowfoam seed oil at 27th make it richer than a typical serum.
• The collagen names are in the tail: seven collagen entries between 61st and 71st, then a long run of amino acids. There is no caffeine entry, the ingredient most de-puffing eye products lean on.
• Fragrance sits 104th, second to last, followed by alpha-isomethyl ionone, a fragrance allergen, at 105th. Low, but present in a product for the eye area.

Our read

A peptide-forward eye serum with a genuinely high peptide block, panthenol and niacinamide, in a silicone and shea base. That is a sensible build for dry, early-aging skin around the eyes. It is not a de-puffer, and the fragrance, though near the bottom, is in a product meant for the most sensitive skin on the face.

Who should skip this

• You want something for morning puffiness. There is no caffeine on this list.
• The skin around your eyes reacts to fragrance. It sits 104th, with a listed allergen right after it.
• You are paying for collagen. Its seven entries sit 61st or lower.

A note on how we read that list. Ingredient lists run in descending order of concentration, but only for ingredients above 1%. Below that, the order is up to the manufacturer, so a low position tells you something is present at a low level, not exactly how much. We do not guess at percentages. FDA labeling guide.

What the listing says

Medicube's own description of this product, as published on its Amazon.com listing. It is marketing copy, not our assessment, and we have not verified the claims in it.

• 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.
