How it works
The D'LEXO Peptide Complex Solution Ampoule is a 35ml ampoule, used after toner and before moisturizer, morning and evening. The peptide it is built around is Nonapeptide-1, named twenty-fifth on its own ingredient list. The same list carries Madecassoside, Adenosine and Asiaticoside, so the peptide is not the only thing on it worth naming. How much of the Nonapeptide-1 stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. This is the Original Korean Formula, the ampoule DERMALINE sells in Korea, Nonapeptide-1 and all.
Key benefits
- Nonapeptide-1, the peptide this ampoule is built around
- Madecassoside, Adenosine and Asiaticoside on the same list, actives
- Dipeptide-2 on the same list, a peptide
- Dipeptide Diaminobutyroyl Benzylamide Diacetate and Acetyl Tetrapeptide-3 further down the same list
- Acetyl Tetrapeptide-5 and Acetyl Hexapeptide-8 further down the same list
- Nonapeptide-1 named twenty-fifth on the manufacturer list printed on this page
How to use
- Use it after toner or essence, before moisturizer, patted in rather than rubbed. AM and/or PM.
Where does this ampoule go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than an ampoule 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 Nonapeptide-1 and not three changes at once.
Is this the Korean-market ampoule or a US version?
The Korean-market one, Nonapeptide-1 and all. We match this ampoule 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 Nonapeptide-1?
Madecassoside, Adenosine and Asiaticoside. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Nonapeptide-1 sits relative to them. Further down the same panel: Dipeptide-2, Dipeptide Diaminobutyroyl Benzylamide Diacetate and Acetyl Tetrapeptide-3.

Ingredient list read from dermaline.co.kr on 30 August 2026.
42 of 42 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.
- 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.
- Erythritol humectant
- Erythritol is a sugar alcohol humectant with a faint cooling feel as it dissolves. It hydrates and helps a formula spread without tack.
- Diethoxyethyl Succinate solvent
- Diethoxyethyl Succinate is a solvent that helps water-resistant actives spread and sink in evenly. It also leaves a light, silky feel.
- Bis-PEG-18 Methyl Ether Dimethyl Silane silicone
- A water-soluble silicone used for a light, silky slip without an oily film. It also helps other ingredients spread evenly.
- 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.
- 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.
- Panthenol humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- 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.
- Polyacrylate Crosspolymer-6 thickener
- Polyacrylate Crosspolymer-6 is a thickener chosen for a notably fresh, bouncy gel feel that breaks down to water on the skin.
- Madecassoside active
- Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.
30 more explained
- Glyceryl Acrylate/Acrylic Acid Copolymer film former
- This is a polymer that forms a moisture-holding film on the surface, usually supplied with glycerin and propylene glycol as a hydrating complex.
- Ethylhexylglycerin preservative booster
- Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
- Citric Acid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
- Adenosine active
- 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.
- PVM/MA Copolymer film former
- PVM/MA Copolymer is a film-forming polymer used to hold a formula in place and, in a mask, to give the peel-off film its strength.
- Polyquaternium-51 film former
- Polyquaternium-51 is a polymer, sometimes sold as Lipidure, built on the same phosphorylcholine structure as a cell membrane. It holds water in a film on the surface and gives a distinctive soft, dry finish.
- 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.
- Asiaticoside active
- Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
- 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.
- 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.
- Ubiquinone antioxidant
- Ubiquinone is coenzyme Q10, an antioxidant every cell uses in its own energy production. In a formula it is oil soluble, faintly yellow, and used for the look of tired, dull skin.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- Nonapeptide-1 peptide
- Nonapeptide-1 is a nine-amino-acid peptide used for the look of uneven tone rather than for firmness, which makes it unusual among cosmetic peptides.
- Dipeptide-2 peptide
- Dipeptide-2 is a two-amino-acid peptide used mainly in eye formulas, for the look of puffiness rather than of lines.
- Dipeptide Diaminobutyroyl Benzylamide Diacetate peptide
- This is a two-amino-acid peptide, sold as Syn-Ake, used for the look of expression lines. Its structure was modelled on a component of snake venom, though nothing of the venom itself is in it.
- Acetyl Tetrapeptide-3 peptide
- Acetyl Tetrapeptide-3 is a four-amino-acid peptide used for the look of density and firmness. It appears in scalp formulas as often as in facial ones.
- Acetyl Tetrapeptide-5 peptide
- Acetyl Tetrapeptide-5 is a four-amino-acid peptide used in eye products for the look of puffiness and crepiness.
- Acetyl Hexapeptide-8 peptide
- Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
- Oligopeptide-1 peptide
- Oligopeptide-1 is a short synthetic peptide. Oligo means the chain is short without the name fixing its length, which is why oligopeptides appear in blends where several sequences work together.
- Copper Tripeptide-1 peptide
- Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
- Tripeptide-1 peptide
- Tripeptide-1 is the copper-free version of the classic three-amino-acid peptide. It is used for the look of firmness in formulas that avoid copper's blue tint.
- Palmitoyl Tetrapeptide-7 peptide
- Palmitoyl Tetrapeptide-7 is a four-amino-acid peptide with a fatty tail, used for the look of fine lines. With palmitoyl tripeptide-1 it forms the pairing sold as Matrixyl 3000.
- Palmitoyl Tripeptide-1 peptide
- 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.
- Palmitoyl Tripeptide-5 peptide
- Palmitoyl Tripeptide-5 is a fatted three-amino-acid peptide used for the look of firmness and fine lines. The palmitoyl tail is what lets it cross an oily surface.
- Palmitoyl Pentapeptide-4 peptide
- Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
- Palmitoyl Hexapeptide-12 peptide
- Palmitoyl Hexapeptide-12 is a fatted six-amino-acid peptide used for the look of firmness, usually as part of a multi-peptide blend.
- Pentapeptide-3 peptide
- Pentapeptide-3 is a five-amino-acid peptide used for the look of expression lines. It is water soluble and is supplied as one part of a peptide blend rather than alone.
- Hexapeptide-11 peptide
- Hexapeptide-11 is a yeast-derived six-amino-acid peptide used for the look of resilience and firmness.
- Hexapeptide-9 peptide
- Hexapeptide-9 is a six-amino-acid peptide used for the look of firmness and elasticity. It is water soluble and appears in peptide blends rather than alone.
- Arginine/Lysine Polypeptide peptide
- A polypeptide built from the amino acids arginine and lysine. It holds water strongly and leaves a smoothing film.

Worth knowing
- Patch test this ampoule on a small area and wait a day before using it more widely, especially with Nonapeptide-1 on the list.
- Introduce this ampoule on its own for the first week, so anything your skin does is traceable to the Nonapeptide-1 rather than to three changes at once.
