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.

7% 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 is niacinamide?

Niacinamide (vitamin B3) helps with uneven tone, visible pores and oil control, and is well tolerated by most skin types.

What the ingredient order actually tells you

• The azelaic acid is declared on the manufacturer's list, and the number is small: Azelaic Acid (100 ppm) at 26th of 47. That is 0.01%. The listing's '99% purity' describes the raw material, not the amount in the bottle.
• Niacinamide at fourth is the substantial active, consistent with the 5% the listing states. Hydrolyzed sponge, the spicules, sits 12th, so expect some prickle even though azelaic acid leads the name.
• The exosomes are declared too: lactobacillus extracellular vesicles 29th at 50 ppm and milk exosomes 34th at 10 ppm. The 7,500 PPM in the product name matches none of these declared strengths, and the list does not say what it measures.
• The plant cluster that recurs across this range, neem, coccinia, holy basil, eggplant, aloe, turmeric and coralline, sits between 13th and 28th. Salicylic acid is the very last entry, at 47th.

Our read

A niacinamide and spicule serum with azelaic acid at a declared 0.01%, far below the 10% or more that leave-on azelaic products usually carry. If you came for azelaic acid's effect on redness and marks, the list says this is not the product for it. As a niacinamide booster with a mild spicule texture effect, it is coherent.

Who should skip this

• You want azelaic acid in a working amount. The list declares 100 ppm, which is 0.01%.
• Your skin dislikes spicules. Hydrolyzed sponge sits 12th.
• You already use a 5% niacinamide product. This repeats it as the fourth ingredient.

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.
