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.co.uk 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.

Ingredients, as listed by Medicube

Taken from Medicube's own product page on 2026-10-18. We have not verified it against a physical pack, and formulations change by market and batch. If an ingredient matters to you, check the pack itself. One more caveat for UK readers: Medicube has no separate UK site, so this list comes from its US product page. UK and EU ingredient lists can differ from the US one, so treat this as indicative until you have the pack in front of you.

What the ingredient order actually tells you

• The listing calls this fragrance-free, with no added artificial scents. The manufacturer's own 17-entry list has no fragrance entry, which squares with that wording, but it does carry three essential oils: eucalyptus 14th, rosemary 15th and tea tree 16th.
• The listing also names its buffer, sodium citrate and citric acid, and the list agrees: they sit ninth and 12th, around a declared 150 ppm of hypochlorous acid at 13th. That is 0.015%, and for this ingredient a low position is expected because it works at parts-per-million strengths.
• The bigger presence is niacinamide, second behind water, with panthenol fifth and allantoin 11th. On ingredient order this is a niacinamide mist that also contains hypochlorous acid.
• The 0.00% irritation index on the listing is a test result the brand quotes. It describes a test panel, not your skin, so a patch test still makes sense if essential oils have bothered you before.

Our read

A niacinamide-led soothing mist with hypochlorous acid at the declared strength, and fragrance-free in the narrow sense the listing uses: there is no fragrance entry, though eucalyptus, rosemary and tea tree oils are present. For daily comfort on normal or combination skin it is a sensible buy. If 'fragrance-free' matters to you because scents irritate, read it as 'no added perfume' rather than 'unscented'.

Who should skip this

• You avoid essential oils. Three sit 14th to 16th, in a product you spray over the whole face.
• You already use a niacinamide serum. This mist repeats that ingredient as its second entry.
• You need hypochlorous acid for a medical skin concern. That is for a doctor or pharmacist; this is a cosmetic mist.

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.
