Medicube Capsule Cream with TXA & Niacinamide for After Spot Care

Overview

The hero ingredient is tranexamic acid, and you use it as your daily moisturizer. With a strong 4.3 out of 5 from 3k ratings, it is a well-liked pick. 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.

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.

11% 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.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.

What is tranexamic acid?

Tranexamic acid is a brightening active that targets stubborn discoloration and post-blemish marks, often paired with niacinamide.

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 headline is honest about one of its two names. Niacinamide sits third of 62, and the manufacturer's list declares it at 50,000 ppm, which is 5% and matches the 5% on the Amazon listing. That is a full working dose, behind only water and glycerin.
• Tranexamic acid, the other name on the front, sits 32nd. The listing's '99% purity' describes the raw material, not how much of it is in the jar, and the order ranks every ingredient across the whole product, red capsules included.
• The other brightening names sit further down still: glutathione 39th, a vitamin C derivative 51st and alpha-arbutin 53rd. Eight hyaluronic entries run from 50th to the last place, and ceramide NP sits 55th.
• No fragrance entry appears, but lemongrass oil and anise oil sit 47th and 48th. They are low, yet they are scent-bearing oils in a cream the listing calls mild enough for all skin types.

Our read

Buy this as a 5% niacinamide cream with tranexamic acid in a supporting role, and the list backs you up. Buy it as a TXA treatment and the order disagrees: the namesake sits 32nd, below the thickeners and emulsifiers. As a daily moisturizer for uneven-looking tone, the third-place niacinamide is the reason it earns a place.

Who should skip this

• You want tranexamic acid as the main active. It sits 32nd of 62, with niacinamide doing the heavy lifting.
• Niacinamide at 5% has made your skin flush or itch before. Here it is the third ingredient.
• You avoid essential oils entirely. Lemongrass and anise oils are on the list, low down but present.

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.
