Where does this sheet mask go in my routine?

After toner, in place of your serum step, in the evening. Toner goes on before it, and the rest of the routine goes on after you take the sheet mask off. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Laminaria Digitata Extract and not three changes at once.

Is this the Korean-market sheet mask or a US version?

The Korean-market one, Laminaria Digitata Extract and all. We match this sheet mask to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.

What else is on the list besides Laminaria Digitata Extract?

Allantoin, Dipotassium Glycyrrhizate and Madecassoside. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Laminaria Digitata Extract sits relative to them. Further down the same panel: Bifida Ferment Lysate, Lactobacillus Ferment and Tocopherol.

How it works

The Refreshing Sea Kelp Real Deep Mask is a sheet mask, used after toner, in place of your serum step, in the evening. The plant extract it is built around is Laminaria Digitata Extract, named seventeenth on its own ingredient list. The same list carries Allantoin, Dipotassium Glycyrrhizate and Madecassoside, so the plant extract is not the only thing on it worth naming. How much of the Laminaria Digitata 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, Laminaria Digitata Extract and all.

Inside the formula

Ingredients declared

No fragrance

on the list

1 of 5

42 of 44 explained

Water(Aqua) solvent: Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
Lactobacillus/Kelp Ferment Filtrate(100,000Ppm) ferment: This is kelp fermented by lactobacillus and then filtered. Fermentation breaks the seaweed polysaccharides into smaller, more soluble pieces than the plain extract carries.
Glycerin humectant: Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
Dipropylene Glycol humectant: Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
Acrylates Copolymer film former: Acrylates Copolymer is a synthetic polymer that forms a film as the water leaves. It holds a formula in place, controls shine and helps a texture stay put.
Ceratonia Siliqua (Carob) Gum thickener: Carob Gum is a seed polysaccharide from the carob tree. It thickens a formula and gives a soft, cushioned body.
Chondrus Crispus plant extract: Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
Sea Water mineral: Sea Water is filtered and desalinated seawater used in place of plain water. It carries magnesium, calcium and potassium, so it brings the mineral balance of the base closer to skin's own.
Betaine humectant: Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
Algin thickener: Algin is a brown-seaweed polysaccharide. It thickens, forms a film, and sets into a rubbery gel when calcium is added, which is how a peel-off modelling mask works.
Agar thickener: Agar is a seaweed polysaccharide that sets into a firm gel. It is the gelling agent behind jelly masks and thick sleeping packs.
Hydroxyacetophenone preservative booster: Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.

30 more explained

1,2-Hexanediol humectant: 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
Potassium Chloride mineral: Potassium Chloride is a mineral salt used to bring a formula closer to the salt balance of skin, most often as part of a sea-water or mineral-water blend.
Sucrose humectant: Sucrose is table sugar, used here as a humectant. It draws water into the outer layer of skin and, in a scrub, doubles as the physical grain.
Caprylyl Glycol preservative booster: Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
Laminaria Digitata plant extract: Oarweed kelp extract. It carries alginates, minerals and iodine and is used as a hydrating, mineral-rich marine ingredient.
Allantoin active: 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.
Xanthan Gum thickener: Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
Polyglyceryl-10 Laurate emulsifier: Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
Ethylhexylglycerin preservative booster: Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
Melia Azadirachta Leaf Extract plant extract: Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin.
Disodium EDTA chelator: EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
Pyrus Communis (Pear) Fruit Extract plant extract: Pear Fruit Extract carries fruit sugars and mild fruit acids. It is used as a hydrating extract with a very light smoothing effect on the surface.
Citric Acid pH adjuster: Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
Rosa Damascena Flower Water plant extract: Rosa Damascena Flower Water is the water left from distilling rose petals. It is used in place of plain water as a base and carries the scent and trace compounds of the distillation.
Iris Florentina Root Extract plant extract: Iris Florentina Root Extract, or orris root, is a long-standing perfumery and skincare ingredient. It is used as a conditioning extract with a soft, powdery scent.
Butylene Glycol humectant: Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
Cucumis Melo (Melon) Fruit Extract plant extract: Melon Fruit Extract carries fruit sugars and a natural antioxidant enzyme system. It is used as a light hydrating extract.
Hedera Helix (Ivy) Leaf/Stem Extract plant extract: Ivy Leaf and Stem Extract carries saponins, plant compounds that foam slightly in water. It is used in body and eye formulas for the look of puffiness.
Laminaria Japonica Extract plant extract: Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
Dipotassium Glycyrrhizate active: Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
Kjellmaniella Gyrata Extract plant extract: Extract of a Japanese kelp. Kelp extracts carry alginate and fucoidan, which hold water and thicken a formula slightly.
Centella Asiatica Extract plant extract: Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
Bifida Ferment Lysate ferment: Bifida Ferment Lysate is a bifidobacteria ferment with the cells broken open. It is the ingredient behind the first-essence category and is used for the look of tired, reactive skin.
Lactose sugar: Lactose is milk sugar. In a formula it is a humectant and a food source for the ferment ingredients declared beside it.
Lactobacillus Ferment ferment: Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin.
Spirulina Platensis Extract plant extract: Spirulina is a blue-green microalga, unusually high in protein. Its extract carries amino acids and the blue pigment phycocyanin, which can tint a formula.
Jania Rubens Extract plant extract: Extract of a red coralline seaweed that builds calcium into its own structure, so the extract is mineral-rich. It is a conditioning marine extract.
Tocopherol antioxidant: Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
Panthenol humectant: Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
Madecassoside active: Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.

How to use

PM: use it after toner, in place of the serum step, a few evenings a week.
Leave it on for the time printed on the packaging rather than guessing at the clock.
Pat in whatever essence remains instead of rinsing it away, then continue with the rest of the routine.

Worth knowing

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