How it works

It is a light fluid that settles closer to matte than most serums do. That finish is why it works under a base, where a slicker layer would move things around. A moisturizer cannot do the same thing here, because it is spread thicker and does more general work. It belongs in the middle of a routine, once the water step is on and before anything occlusive. You can judge it on how quickly it settles and how the face looks once the cream is on over it.

Key benefits

  • targets the look of dullness and dark spots specifically
  • supports skin's own renewal processes over time
  • supports a plumper, less dehydrated look through the day
  • concentrates its formula into a single, fast-absorbing step
  • carries the intact Korean-market packaging and batch code rather than an over-labeled substitute

Key actives

Niacinamide

A barrier-supporting brightening agent that works on visible tone evenness and pore appearance. In this formula it works on the look of tone and dark spots rather than on texture or hydration, so it is doing a job the rest of the ingredient list is not.

Vigna Radiata Seed Extract

Mung bean seed extract, the brand's core botanical, used here for its mattifying, pore-refining effect on oily skin.

Adenosine

An approved Korean anti-wrinkle functional ingredient that supports skin's own natural renewal. It is included for renewal and resilience support, a different lane from the hydration and soothing work the rest of the formula does.

Hyaluronic Acid

A humectant that binds many times its weight in water at the surface. It works on water content specifically, which is a different job from the botanicals and actives elsewhere on the same ingredient list.

Phaseolus Radiatus Seed Extract

Mung bean extract used for its traditional pore-refining, mattifying effect. In this formula it works on the look of tone and dark spots rather than on texture or hydration, so it is doing a job the rest of the ingredient list is not.

How to use

  1. Apply it after your toner, while the face is still slightly damp, so a thin layer spreads without dragging.
  2. Three or four drops cover the whole face; press it in with the flats of the fingers rather than rubbing.
  3. Follow with a moisturizer within a minute so the thin layer has something holding it down.
  4. Do not stack it under a second serum doing the same job, since more layers is not the same as more result.

Worth knowing

  • Patch test on a small area of the jaw first if your skin reacts easily to something new.
  • Give it thirty seconds before the next layer so nothing balls up under a base.

What professionals say

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

  • Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.

    Samantha Stein, PA-CDermatology physician assistant, Cleveland Clinic
  • Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
