How it works

Hydrolyzed Sponge is named on the ingredient panel on this ampoule. Hydrolyzed Sponge is processed freshwater sponge, which carries fine silica spicules. In a formula it works as a mild physical exfoliant. On this panel it sits alongside Niacinamide, Adenosine and Lactobacillus Extracellular Vesicles. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Key actives

Hydrolyzed Sponge

Hydrolyzed Sponge is processed freshwater sponge, which carries fine silica spicules. In a formula it works as a mild physical exfoliant.

Niacinamide

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Adenosine

Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.

Lactobacillus Extracellular Vesicles

Lactobacillus Extracellular Vesicles are the tiny membrane-bound packets bacteria release. They are a recent Korean formulation ingredient used as a conditioning ferment component.

How to use

  1. Use it in the evening after toner, before moisturizer, on clean and dry skin.
  2. Three or four drops for the whole face, or fewer over the nose and chin alone.
  3. Press it in, wait a minute, then a moisturizer over the top of it.
  4. Two or three evenings a week. Do not move up a grade until this one has been uneventful for a month.

Worth knowing

  • Patch test on the inner arm before the first full-face application, especially on skin that reacts easily to new products.
  • Stop use and rinse off if stinging, burning, or new redness shows up rather than pushing through discomfort.

  • Those bacteria are essential to fight infection, protect against environmental damage, regulate pH levels and keep the skin hydrated and healthy.

  • 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.
