How it works

Hydrolyzed Sponge is named on the ingredient panel on this serum. 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 and Adenosine. 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.

Payment and security

How to use

  1. Use it in the evening after toner, as the step up from the 2000 grade rather than a first ampoule.
  2. Three or four drops for the face, with a lighter hand around the eyes and the corners of the mouth.
  3. Press it in, give it a minute, and follow with a moisturizer every time.
  4. Every other evening. Do not use it on a night you have already exfoliated, even lightly.

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.

What skin-care professionals say about skin care, quoted from the medical sources linked beside each.

  • Pretty much every step of a Korean skin care routine is going to have some component of hydration.

  • 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.
