How it works
The 5 Peptide Ceramide Barrier Comfort Lip Mask is a lip mask, used as the last thing before bed, on clean lips. The barrier lipid it is built around is Ceramide NP, named thirty-sixth on its own ingredient list. The same list carries Sodium DNA, Gluconolactone and Lactic Acid, so the barrier lipid is not the only thing on it worth naming. How much of the Ceramide NP stays on the skin, and for how long, is decided by the lip mask format rather than by the list alone. COSRX sells this Ceramide NP lip mask in Korea, and this is that version.
Key benefits

- Gluconolactone and Lactic Acid on the same list, exfoliants
- Palmitoyl Tripeptide-1 on the same list, a peptide
- Acetyl Hexapeptide-8 and Tripeptide-1 further down the same list
- Palmitoyl Tetrapeptide-7 and Palmitoyl Hexapeptide-12 further down the same list
Key actives
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 the entry this lip mask is named after, and the list carries it.
Sodium DNAactive
Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to. It is named forty-eighth on this lip mask's list, alongside Ceramide NP.
Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. It is named thirty-seventh on this lip mask's list, alongside Ceramide NP.
Lactic Acidexfoliant
Lactic Acid is a larger AHA than glycolic, so it works nearer the surface and is easier on skin, and it is a humectant as well as an exfoliant. It is the AHA of choice for dry skin. It is named fortieth on this lip mask's list, alongside Ceramide NP.
Palmitoyl Tripeptide-1peptide
Palmitoyl Tripeptide-1 is a short peptide with a fatty tail added so it can travel through the oily outer layer of skin. It is used for the look of firmness and is almost always paired with palmitoyl tetrapeptide-7. The panel names it forty-third on this lip mask's list, beside Ceramide NP.
COSRX 5 Peptide Ceramide Barrier Comfort Lip Mask
Where does this lip mask go in my routine?
As the last thing before bed, on clean lips. Anything thinner than a lip mask goes on before it, and anything richer goes on after. 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 Ceramide NP and not three changes at once.
Does this lip mask contain fragrance?
Yes. The ingredient list names Fragrance and Parfum. 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 lip mask is not the one.
What else is on the list besides Ceramide NP?
Sodium DNA, Gluconolactone and Lactic Acid. The order they are printed in on this lip mask's panel is the order on the box, so you can see where Ceramide NP sits relative to them. Further down the same panel: Palmitoyl Tripeptide-1, Acetyl Hexapeptide-8 and Tripeptide-1.

How to use
- Use the 5 Peptide Ceramide Barrier Comfort Lip Mask as the last thing before bed, on clean lips.
- A thick layer, more than you would use for a daytime balm, taken to the lip line and left there.
- It goes on after your evening routine is finished, and nothing goes over it.
- Nightly, or on the nights lips feel dry. Do not lick or blot it off before sleeping; it needs the whole night in place.
Worth knowing
- Patch test this lip mask on a small area and wait a day before using it more widely, especially with Ceramide NP on the list.
- This list names Fragrance and Parfum, so skip it if fragrance components are something you avoid.
- Gluconolactone and Lactic Acid on this list makes this lip mask an exfoliating step, so do not stack it with another one on the same night.

Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.

This means that gluconolactone acts as an exfoliating acid, but also as a moisturizer. It has moisturizing, soothing, and lightening properties, working well on dry skin.
