Dark spots, post-blemish marks and uneven patches look visibly faded — and tone stays even.

You have tried brightening creams that did nothing and harsh acids that left skin red and flaking. Meanwhile every month lays fresh discolouration on top of the old. The longer pigmentation sits, the more stubborn it looks — waiting is the most expensive option on the table.

medicube TXA Niacinamide 15% Serum pairs two tone-correcting actives in one step. TXA is tranexamic acid, an ingredient prized in Korean dermocosmetics for visibly fading the look of stubborn, concentrated discolouration. Niacinamide — a form of vitamin B3 — sits at a full 15%, a genuinely high concentration by any market standard. Used together, they are one of the most requested pigmentation pairings in Korean skincare. The serum comes from medicube, one of Korea's leading dermocosmetic brands, built for the most demanding skincare market in the world.

  • Stubborn dark spots and post-blemish marks look visibly lighter over time. Tranexamic acid targets the look of concentrated discolouration exactly where ordinary brightening creams give up.
  • Overall tone looks brighter and more uniform. Niacinamide at 15% works across the whole face, evening the look of patchiness rather than spot-treating alone.
  • Pores look refined and excess shine stays under control. Niacinamide is equally valued for visibly smoothing texture and balancing oily areas.
  • Gentle enough for daily use, morning and night. The lightweight, fast-absorbing formula slots into any routine without the sting or flaking of harsh acids.

Discolouration looks worse when new marks appear faster than old ones fade. This serum works the visible side of both at once — which is exactly why the pairing became a Korean skincare staple.

This is for the woman who edits dark patches out of photos and layers concealer over the same three spots every single morning.
