How it works
The Marine Anti-Blemish Mask is a 5ea sheet mask, used after toner, in place of your serum step, in the evening. The ferment it is built around is Lactobacillus Ferment Lysate, named thirtieth on its own ingredient list. The same list carries Saccharomyces Ferment, Bifida Ferment Lysate and Cholesterol, so the ferment is not the only thing on it worth naming. How much of the Lactobacillus Ferment Lysate 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 Dr.Althea sells in Korea, Lactobacillus Ferment Lysate and all.
Key benefits

- Hydrolyzed Collagen and Spirulina Platensis Extract further down the same list
- Perilla Ocymoides Seed Extract and Chlorella Vulgaris Extract further down the same list
- Lactobacillus Ferment Lysate named thirtieth on the manufacturer list printed on this page

Dr. Althea Marine Anti-Blemish Mask (5 Sheets)
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 Lactobacillus Ferment Lysate and not three changes at once.
Is this the Korean-market sheet mask or a US version?
The Korean-market one, Lactobacillus Ferment Lysate 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 Lactobacillus Ferment Lysate?
Saccharomyces Ferment, Bifida Ferment Lysate and Cholesterol. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Lactobacillus Ferment Lysate sits relative to them. Further down the same panel: Ceramide NP, Hydrolyzed Collagen and Spirulina Platensis Extract.

Ingredient list read from whatsinmyjar.com on 10 September 2026.
35 of 38 explained
- Water 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.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- 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.
- 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.
- 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.
- Hexylene Glycol solvent
- Hexylene Glycol is a solvent and light humectant. It keeps ingredients that resist water in solution and thins a formula so it spreads evenly.
- Hydrolyzed Jojoba Esters emollient
- Jojoba Esters are jojoba wax rebuilt into a softer, meltable form. They condition skin and give body to balms without the heaviness of a butter.
- 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.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Cetearyl Olivate emulsifier
- Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's own.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
23 more explained
- 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.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Sorbitan Olivate emulsifier
- Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
- Polyglyceryl-10 Myristate emulsifier
- Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.
- 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.
- 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.
- 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.
- 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.
- Perilla Ocymoides Seed Extract plant extract
- Perilla seed extract, from the herb Korean cooking knows as kkaennip. The seed is high in omega-3 fatty acids and the extract carries rosmarinic acid.
- Hydrolyzed Collagen protein
- Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
- 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.
- Chlorella Vulgaris Extract plant extract
- Chlorella Vulgaris is a freshwater green algae. Its extract carries proteins, chlorophyll and amino acids and is used as a conditioning ingredient.
- 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.
- Caprylic/Capric Triglyceride emollient
- Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
- Rosa Damascena Flower Oil fragrance component
- Rosa Damascena Flower Oil is rose essential oil, one of the most expensive materials in perfumery. It scents a formula, and like every essential oil it is a class reactive skin often does not tolerate.
- Hydrogenated Lecithin emulsifier
- Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
- Lactobacillus Ferment Lysate ferment
- Lactobacillus Ferment Lysate is the ferment with the bacterial cells broken open, so their contents are in the formula too. It is a conditioning ferment used in barrier-focused products.
- 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.
- Undaria Pinnatifida Extract plant extract
- Extract of the brown seaweed Korean cooking calls miyeok. It carries fucoidan and alginates, both strong water-holding polysaccharides.
- 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.
- Hizikia Fusiforme Extract plant extract
- Tot, a Korean brown seaweed eaten as a side dish. Its extract is mineral rich and used as a hydrating marine ingredient.
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
- Ceramide NP barrier lipid
- Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.

How to use
- Use the Marine Anti-Blemish Mask in the evening, after cleansing, in place of your toner and serum layers.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face.
Worth knowing
- Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Lactobacillus Ferment Lysate on the list.
- Introduce this sheet mask on its own for the first week, so anything your skin does is traceable to the Lactobacillus Ferment Lysate rather than to three changes at once.
