Brighter, more even skin in 20 minutes. This Korean sheet mask from Round Lab goes after dark spots, post-acne marks, and that dull, tired look — with 5% niacinamide plus glutathione and tranexamic acid working on pigment from three different angles. The essence is built on sea buckthorn water, so every drop is doing brightening work. Single mask or box of 10.

  • 5% Niacinamide — the concentration with clinical evidence behind it. Fades dark spots, refines texture, and evens out tone.
  • Sea Buckthorn Water Base — from sunny Gangwon, cold-extracted to protect the vitamins and antioxidants. Replaces plain water so the whole formula brightens.
  • Glutathione — interrupts pigment at a different stage than niacinamide, so the two reach more together than either alone.
  • Tranexamic Acid — works on the stubborn marks that don't respond to niacinamide by itself.
  • Vitamin C Derivatives — sodium ascorbyl phosphate and 3-O-ethyl ascorbic acid, stable forms that brighten without the sting of pure vitamin C.
  • Gluconolactone — a PHA that smooths texture and hydrates at the same time, gentle enough for a daily mask.
  • Bisabolol + Allantoin — the calming layer, which is what lets you use a brightening mask on reactive skin.
  • Box of 10 for Consistency — brightening works on repetition, not one-offs. Ten masks is enough to use every other day for three weeks.

After cleansing and toner, unfold the mask and lay it evenly across your face. Leave on 10–20 minutes. Remove and pat the remaining essence into your skin — no need to rinse. Follow with moisturizer, and SPF in the morning. Sun exposure undoes brightening faster than any mask builds it.
