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 actives
Lactobacillus Ferment Lysateferment
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. On this sheet mask's own ingredient list it is named thirtieth.
Saccharomyces Fermentferment
Saccharomyces Ferment is a brewer's yeast ferment. It supplies amino acids, sugars and B vitamins and is used as a conditioning, hydrating ferment. It is named thirty-first on this sheet mask's list, alongside Lactobacillus Ferment Lysate.
Bifida Ferment Lysateferment
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. It is named thirty-second on this sheet mask's list, alongside Lactobacillus Ferment Lysate.
Cholesterolbarrier 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. It is named thirty-sixth on this sheet mask's list, alongside Lactobacillus Ferment Lysate.
Ceramide NPbarrier 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. It is named thirty-seventh on this sheet mask's list, alongside Lactobacillus Ferment Lysate.

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.

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.
