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.

5 star 72%
4 star 15%
3 star 5%
2 star 3%
1 star 5%

8% 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 the ingredient order actually tells you

  • The '4X retinoid' claim checks out: there are four vitamin A entries. Retinal sits 26th of 75, then retinol 55th, retinyl acetate 56th and hydroxypinacolone retinoate 57th. Retinal, the one the listing quantifies at 0.15%, is also the best placed.
  • Volufiline is a supplier's blend of a plant extract in an oil carrier, so the 5% on the listing describes the blend. The extract itself, anemarrhena root, sits 51st, and the micro spicules, hydrolyzed sponge, sit 60th, far lower than in Medicube's spicule-led serums.
  • The base is a cream-serum: hydrogenated polyisobutene third, a triglyceride fourth and cetearyl alcohol sixth, with niacinamide seventh and panthenol 11th.
  • No fragrance entry appears, but five scent-bearing oils do: amyris 47th, angelica root 62nd, galbanum 64th, bitter orange leaf 65th and jasmine 66th. The listing calls the serum suitable for sensitive skin, and this is the line on the list to weigh against that.
Our read

A genuine retinal serum, with four retinoids as advertised, in a creamy base with niacinamide high up. The plumping story leans on Volufiline, whose anemarrhena extract sits 51st, and the spicules are a trace, so judge it as a retinal night serum. Introduce it slowly, keep sunscreen in the morning, and note the five essential oils if your skin is reactive.

Who should skip this

  • Your skin is sensitive to essential oils. Five sit between 47th and 66th.
  • You are pregnant or trying to conceive. This carries four retinoids, the class doctors usually advise avoiding then.
  • You wanted a spicule treatment. Hydrolyzed sponge sits 60th of 75 here.

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.
