COSRX The Peptide Collagen Lifting Glow Hydrogel Mask 34g X 3ea
Six peptides and five ceramides, for less than a serum.
One of them is Copper Tripeptide-1 — the expensive one.
Wear it two hours, or overnight.
What this mask does
A 34 g hydrogel mask, three to a box, carrying six peptides including Copper Tripeptide-1, the full five-ceramide set with Cholesterol and Phytosphingosine, Hydrolyzed Collagen and six hyaluronates.
The peptide list, named
Six is an unusual number for a sheet mask. Here they are: Acetyl Hexapeptide-8, Palmitoyl Tripeptide-5, Dipeptide Diaminobutyroyl Benzylamide Diacetate, Copper Tripeptide-1, Acetyl Tetrapeptide-2 and Palmitoyl Tripeptide-8.
Copper Tripeptide-1 is the one worth pointing at. It is expensive, it is the peptide with the longest research history behind it, and it is usually reserved for products at several times this price. It sits low on the list, as peptides always do — they are used at fractions of a percent by design.
The barrier set behind them
Ceramide NP, NS, AP, AS and EOP all appear, with Cholesterol and Phytosphingosine. That is the complete lipid architecture of the skin barrier — the same set used in serious barrier creams — not one ceramide standing in for the family.
Add Hydrolyzed Collagen, six hyaluronates, Niacinamide, Adenosine and Acetyl Glucosamine, and the list stops looking like a mask and starts looking like a treatment worn for three hours.
Key ingredients
Ingredient · What it is, and what it is used for
- Copper Tripeptide-1
- Copper-bound tripeptide, GHK-Cu. Studied for the look of firmness.
- Palmitoyl Tripeptide-5
- Palmitoylated signal tripeptide.
- Palmitoyl Tripeptide-8
- Palmitoylated tripeptide.
- Acetyl Hexapeptide-8
- Synthetic hexapeptide, the one sold as argireline. Studied for the look of expression lines.
- Acetyl Tetrapeptide-2
- Synthetic tetrapeptide.
- Hydrolyzed Collagen
- Collagen broken into fragments small enough to stay dissolved. It holds water at the surface — it does not become your collagen, and nothing applied to skin does.
- Ceramide NP
- Ceramide 3. A material skin already contains, so it reads as its own.
- Ceramide EOP
- Ceramide 1.
- Cholesterol
- Sterol. One of the three lipid classes skin's outer layer is built from — ceramides and fatty acids are the other two, and they work as a set rather than alone.
- Phytosphingosine
- Sphingoid base. The backbone that ceramides are built on, and it occurs in your own lipid layer.
- Niacinamide
- Vitamin B3. Studied for evening out the look of tone, for the look of pores, and for breakout-prone skin — which is why it turns up in so much of this catalogue.
- Acetyl Glucosamine
- Acetylated amino sugar.
How the formula works together
The gel is built from carob gum, Chondrus Crispus, agar, Sclerotium Gum and cellulose gum, set with Potassium Chloride and sweetened structurally with Erythritol and Sucrose. That network holds its own water, which is why the mask can be worn for hours — or overnight, as the brand suggests — without drying out and pulling water back off the face.
Inside it: peptides for signalling, the ceramide-cholesterol-phytosphingosine trio for the barrier, the hyaluronate family for water, and Niacinamide with Adenosine as the two conventional actives.
Forty-nine ingredients, no fragrance and no essential oil on the list.
Who it is for
Labelled for all skin types, aimed at firmness and glow. Three to a box because it is an evening, not a nightly step.
How to use it
- Cleanse, then apply toner or serum first.
- Open the pouch, peel the films and fit the mask.
- Leave two to three hours, or until the gel turns transparent. It can be worn overnight.
- Remove and massage in what remains.
