K-beauty, read closely — ingredients, textures, and the choices between them.
medicube
A 30 mL leave-on capsule serum featuring kojic acid, turmeric, niacinamide and vitamin E. The official package image reads “Kojic Acid | Turmeric 1%” and “Niacinamide 5%”; the full ingredient list does not give separate percentages for each named ingredient.
| Amazon US listing | 30 mL / 1.01 fl oz |
|---|---|
| Format | Leave-on serum with microcapsules |
| Package claims | Package label: “Kojic Acid | Turmeric 1%” · “Niacinamide 5%” |
| Listed ingredients | Kojic acid · turmeric root extract · niacinamide · glycolic acid |
Consider it if you want a leave-on formula organized around kojic acid, turmeric and niacinamide, with visible capsule beads. Compare the full formula with other tone-focused serums rather than assuming the capsule appearance predicts results.
Based on brand information and published sources, not a hands-on review.
01 / TEXTURE
Medicube describes snowflake-like capsules containing squalane and thioctic acid that melt as you spread the serum.
03 / YOUR ROUTINE
After cleansing, apply a few drops and pat evenly until absorbed. Medicube says the capsules do not need to be broken first and describes daily morning and evening use.
The ingredient list includes Chamaecyparis Obtusa Wood Oil and glycolic acid. The brand reports clinical percentage changes but does not show participant count, control or full protocol in the product page; those numbers are not a personal-results guarantee.
CHOOSING THIS FORMULA
The 30 mL package places the 1% claim beside “Kojic Acid | Turmeric” and separately states “Niacinamide 5%.” The ingredient list names kojic acid, turmeric root extract and niacinamide but does not state a separate concentration for each named ingredient.
The brand says to use a few drops after cleansing and pat evenly until absorbed. It says there is no need to break the capsules first. Medicube also says the serum can be used morning and evening. If that frequency does not suit your routine, follow the product label and your own tolerance rather than treating a brand suggestion as a requirement.
The ingredient list also names niacinamide, tocopherol, squalane, thioctic acid and glycolic acid, as well as Chamaecyparis obtusa wood oil. Medicube describes visible capsules that release as you spread the serum; their appearance does not reveal separate ingredient concentrations or predict how the formula will feel.
Medicube reports changes in the skin moisture barrier, brightness and redness and names the Global Institute of Dermatological Sciences. The product page does not state the participant count, control group, measurement method or full protocol. Treat these as manufacturer-reported results, not a promise of the same changes for you.
Anua Rice Ceramide 7 Hydrating Barrier Serum is another leave-on serum on this site, but its name and formula focus differ. Compare the actual listed ingredients and placement in your routine: this Medicube formula names kojic acid, turmeric and glycolic acid, while the Anua product is presented around rice and ceramide. Neither capsule appearance nor branding establishes which one will suit you better.

Your notes and saved routine stay in this browser. They are private records, not public reviews or a test of a product’s effects.
Calculations use complete ingredient lists for the stated market and product version. Listed names do not establish concentrations, equivalent effects or allergy suitability.
Explore products in the same use group with overlapping ingredient lists, then compare their texture, directions and ingredient differences.
Candidates share the page’s language, market context and use group and have a complete ingredient list available. Names are normalized for spacing and reviewed synonyms; duplicate names count once.
The default order divides shared names by all distinct names across both lists: 10 shared names out of 20 distinct names gives 10 ÷ 20. You can instead order by the number of shared names. Up to five candidates are shown.
Ingredient overlap does not establish equivalent effects or a cheaper substitute. Concentrations, ingredient order, finished-product tests and feel are not part of this calculation. Missing lists are not treated as missing ingredients.
