Key actives
Ascorbic Acidantioxidant
Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone. The name on the box points at it, and it is named thirty-fifth on this sleeping mask's own ingredient list.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named eighth on this sleeping mask's list, alongside Ascorbic Acid.
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 thirtieth on this sleeping mask's list, beside Ascorbic Acid.
Lactobacillus Fermentferment
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. It is named thirty-eighth on this sleeping mask's list, alongside Ascorbic Acid.
Bioflavonoidsantioxidant
Bioflavonoids is a collective declaration for the flavonoid fraction of a plant extract, usually citrus. It names a class of plant antioxidants rather than one compound. It is named thirty-third on this sleeping mask's list, alongside Ascorbic Acid.
How to use
- Use this sleeping mask PM, as the last step, as the overnight leave-on mask, in place of or layered under a night cream. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.
Where does this sleeping mask go in my routine?
As the final step of the evening routine, over your usual moisturizer or in place of it. Toner goes on before it, and the rest of the routine goes on after you take the sleeping 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 Ascorbic Acid and not three changes at once.
Does this sleeping mask contain fragrance?
Yes. The ingredient list names Farnesol, Geraniol, Limonene and Linalool. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this sleeping mask is not the one.
What else is on the list besides Ascorbic Acid?
Niacinamide, Adenosine and Lactobacillus Ferment. The order they are printed in on this sleeping mask's panel is the order on the box, so you can see where Ascorbic Acid sits relative to them. Further down the same panel: Bioflavonoids, Thymol Trimethoxycinnamate and 3-O-Ethyl Ascorbic Acid.

How it works
The Yuja Vitamin C Brightening Sleeping Mask is a 70ml sleeping mask, used as the final step of the evening routine, over your usual moisturizer or in place of it. The antioxidant it is built around is Ascorbic Acid, named thirty-fifth on its own ingredient list. The same list carries Niacinamide, Adenosine and Lactobacillus Ferment, so the antioxidant is not the only thing on it worth naming. How much of the Ascorbic Acid stays on the skin, and for how long, is decided by the sleeping mask format rather than by the list alone. HANYUL sells this Ascorbic Acid sleeping mask in Korea, and this is that version.
Worth knowing
- Patch test this sleeping mask on a small area and wait a day before using it more widely, especially with Ascorbic Acid on the list.
- This list names Farnesol, Geraniol and Limonene, so skip it if fragrance components are something you avoid.

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.
