Medicube Hypochlorous Acid Peel-Off Sheet Mask 3EA

Overview

The hero ingredient is hyaluronic acid, and you use it as a targeted treatment step. With a solid 4.1 out of 5 from 248 ratings, it is generally well received. It is one of the gentler options in the range, so it suits most skin types including sensitive skin.

The summary above follows how Medicube markets this product. We also read the published ingredient list line by line, and it tells a different story: what the ingredient order actually says.

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.

14% of these ratings are one or two stars. That is well above the 6% median for the Medicube range. This is one of the more divisive products in the catalogue: most people like it, but a meaningful minority does not, and the average hides that.

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 is hyaluronic acid?

Hyaluronic acid is a humectant that draws in and holds moisture, giving lightweight, dewy hydration without heaviness.

What the ingredient order actually tells you

• Despite 'peel-off' in the name, this is not a film-forming gel. There is no polyvinyl alcohol, the film former in peel-off gels; the peel is the 1.5 mm sheet itself, left on for about 30 minutes until it dries.
• Hypochlorous acid sits 19th of 40, and unlike the Power Soothing Spray, this list does not declare its strength. It follows thickeners, humectants and citric acid at 17th, so read it as a supporting ingredient.
• Nothing on the list exfoliates chemically: there is no glycolic, lactic or salicylic acid, and no gluconolactone. The 'subtle white residue' the listing invites you to look for is a visual cue, not something the ingredient list can explain.
• Where the list is generous is moisture: seven hyaluronic entries from 20th to 36th, panthenol at 21st, and four ceramides, NS, NP, EOP and AP, closing the list at 37th to 40th. No fragrance entry appears.

Our read

A hydrating sheet mask that dries on the face and peels away in one piece, with hypochlorous acid at 19th and a respectable moisture cast. It is a pleasant, unfragranced treat for sensitive or dehydrated skin. It is not an exfoliating mask, whatever the peel suggests, so do not expect it to clear pores the way an acid would.

Who should skip this

• You want a mask that exfoliates. No exfoliating acid is on this list.
• You are buying it for the hypochlorous acid. It sits 19th of 40, with no declared strength.
• Sheet masks that tighten as they dry feel uncomfortable to you. This one stays on until it is fully dry.

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.

• [Gentle Peel-Off Sheet Mask] A gentle peel-style mask that lightly interacts with surface buildup. After removal, lightly wet the sheet to see subtle white residue. Formulated with Hypochlorous Acid to help support balanced-looking pores and overall skin clarity - without squeezing.
• [Infused with Hypochlorous Acid] Formulated with Hypochlorous Acid, known for its skin-calming and purifying properties. Helps improve the look of excess sebum while supporting a clearer, healthier-looking skin appearance and refined-looking pores.
• [Moisture-Balancing aftercare] A synergistic blend of Hyaluronic Acid, Ceramides, and Panthenol replenishes moisture after clarifying care, helping skin feel hydrated, balanced, and comfortable.
• [1.5mm Ultra-Thin Fit Sheet] An ultra-slim 1.5mm sheet is designed to closely follow facial contours for even, comfortable coverage. The sheet stays smoothly in place without lifting, helping deliver consistent care across curved and hard-to-fit areas of the face.
• [How to Use] 1. After cleansing, remove one side of the protective film, apply the mask to dry skin, then remove the remaining film. 2. Leave on for about 30 minutes until fully dry, then gently peel off. 3. To see the result more clearly, lightly wet the removed mask and observe the excess oil and surface impurities that have been collected.
