How it works

The Bio-Collagen Real Deep Mask is a 34g sheet mask, used after toner, in place of your serum step, in the evening. The protein it is built around is Collagen Extract, named twenty-fifth on its own ingredient list. The same list carries Niacinamide, Allantoin and Adenosine, so the protein is not the only thing on it worth naming. How much of the Collagen Extract stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. This is the Original Korean Formula, the sheet mask Biodance sells in Korea, Collagen Extract and all.

Key benefits

  • Collagen Extract, the protein this sheet mask is built around
  • Niacinamide, Allantoin, Adenosine and Dipotassium Glycyrrhizate on the same list, actives
  • Galactomyces Ferment Filtrate and Lactobacillus Ferment further down the same list
  • Bifida Ferment Filtrate and Lactobacillus Ferment Lysate further down the same list
  • Collagen Extract named twenty-fifth on the manufacturer list printed on this page
  • Original Korean Formula, the sheet mask sold on Korean shelves

Key actives

Collagen Extractprotein

Collagen Extract is a collagen-bearing extract, usually from fish skin or scales. In a formula it works as a humectant and a smoothing film rather than as a source of new collagen. The name on the box points at it, and it is named twenty-fifth on this sheet mask's own ingredient list.

Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named fourth on this sheet mask's list, alongside Collagen Extract.

Allantoinactive

Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. It is named seventeenth on this sheet mask's list, alongside Collagen Extract.

Adenosineactive

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. The panel names it twenty-first on this sheet mask's list, beside Collagen Extract.

Dipotassium Glycyrrhizateactive

Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named twenty-ninth on this sheet mask's list, alongside Collagen Extract.

How to use

  1. On cleansed, toned skin, any time of day the routine allows twenty to thirty minutes undisturbed.
  2. Unfold the hydrogel sheet fully and press it against the face, working from the center outward so it sits flat rather than trapping air.
  3. Leave for twenty to thirty minutes, until the film has thinned and turned translucent. Do not remove it early.
  4. Peel off gently and pat any residue into the skin rather than rinsing it away: the film has left real serum behind.

Worth knowing

  • Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Collagen Extract on the list.
  • Introduce this sheet mask on its own for the first week, so anything your skin does is traceable to the Collagen Extract rather than to three changes at once.

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.

  • Topical collagen is a very large molecule that's too big to absorb into the skin.

    Michelle Henry, MDDermatologist, Cosmopolitan
  • Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

    Wilma Bergfeld, MDDermatologist, 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.
