Medicube lists dark spots or marks left after breakouts among the concerns for its Kojic Acid Turmeric, TXA Niacinamide, Deep Vita C, Glutathione and Azelaic Acid lines. Each line is named after its key ingredients. Niacinamide (vitamin B3) is in every product below, so the lead ingredient and the format are what set the lines apart.

Lead ingredients and formats
  • Kojic Acid Turmeric: kojic acid with turmeric root extract, in a toner, a serum, a gel mask and a capsule cream.
  • TXA Niacinamide: tranexamic acid (TXA), in a serum and a capsule cream.
  • Deep Vita C: vitamin C with sea buckthorn water, in a capsule cream.
  • Glutathione: glutathione, in a serum.
  • Azelaic Acid: 16% azelaic acid, in a serum that Medicube also makes for excess oil and clogged-looking pores.

Medicube makes the PDRN Pink Collagen line for uneven-looking tone too, alongside dryness, dullness and loss of firmness, and it names dark spots among the concerns for that line’s toner pads. Our guide to the PDRN Pink Collagen line covers it.

Kojic Acid Turmeric

Each product below pairs kojic acid with turmeric root extract and adds niacinamide: 5% in the toner, serum and capsule cream, and 2% in the gel mask. Medicube does not publish a kojic acid percentage. The serum’s label shows 1% beside kojic acid and turmeric. Medicube makes the line for dullness, uneven-looking tone and dark spots.

TXA Niacinamide

Medicube makes this line for the look of dark spots, marks left after breakouts and uneven skin tone.

  • TXA Niacinamide 15 Serum, 30ml: Medicube publishes 5% TXA, 10% niacinamide and 2% arbutin. The 15 in the name is the 5% TXA plus the 10% niacinamide, not 15% niacinamide. Medicube says 5% is its highest TXA concentration. The pink colour can fade in light, which Medicube says does not change how the serum works.
  • TXA Niacinamide Capsule Cream: red TXA capsules in a red gel, with 5% niacinamide. Medicube does not publish a separate TXA percentage for the cream.
Deep Vita C

The Deep Vita C Capsule Cream has gold capsules in a clear gel. Medicube says the capsules hold 50% sea buckthorn water, 5% niacinamide, pure vitamin C and five vitamin C derivatives, and that the liposome capsules protect the vitamin C from oxidation until you apply it. Medicube makes it for dullness, uneven-looking tone and dark spots, and lists it for all skin types.

Glutathione

The Glutathione Glow Serum leads with glutathione, alongside niacinamide and adenosine. It goes on after toner and before moisturiser. Medicube makes it for dullness, uneven-looking tone and dark spots. It was sold before as the AGE-R Glutathione Glow Serum. Medicube has since changed the bottle, the size and the ingredients, and some shops still list it under the old name.

Azelaic Acid

The Azelaic Acid 16 BB Calming Serum has a 16% azelaic acid complex with niacinamide and pantothenic acid. Medicube makes it for excess oil, clogged-looking pores, rough texture and marks left after breakouts.

Medicube notes that azelaic acid at this level can leave a slight white residue, and suggests thin layers, each left to absorb before the next. Our product page says to start with once a day and move to twice a day if your skin is comfortable.

Cautions before you start

Every product page linked above says to patch-test. Apply a little to a small area before you use a product all over, and stop using it if irritation develops.

  • Resurfacing Toner: Medicube says it can cause mild tingling and leave a temporary white residue. Do not use it straight after shaving or waxing, or on irritated or broken skin. If your skin reacts strongly, Medicube suggests using it on only 2 or 3 evenings a week and not combining it with strong exfoliants (BHA, LHA or high-strength AHA), retinoids or high-strength vitamin C. Medicube also says not to leave it on soaked cotton pads as a mask, which can increase irritation.
  • Other acids and retinol: the Kojic Acid Turmeric Niacinamide Serum contains glycolic acid. Retinol is in the ingredient lists of the Kojic Acid Turmeric gel mask and capsule cream.
  • Fragrance and plant oils: the Deep Vita C Capsule Cream, Kojic Acid Turmeric gel mask and Glutathione Glow Serum contain added fragrance. The TXA Niacinamide 15 Serum carries Medicube’s “No Artificial Fragrance” badge, but its ingredient list includes rose flower oil. The Resurfacing Toner contains lavender and bergamot oils, the Kojic Acid Turmeric serum hinoki wood oil and the TXA Niacinamide Capsule Cream lemongrass and anise oils.
  • Sunscreen: our pages for the products linked above, apart from the TXA Niacinamide 15 Serum, say to use sunscreen during the day or in the morning. We do not sell sunscreen.
