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 Niacinamide and not three changes at once.

What else is on the list besides Niacinamide?

Adenosine, Palmitoyl Tripeptide-5 and Nonapeptide-1. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Acetyl Hexapeptide-8, Copper Tripeptide-1 and Tripeptide-1.

How it works

The Laser Rejuvenation Ampoule is a 30ml ampoule, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named fifth on its own ingredient list. The same list carries Adenosine, Palmitoyl Tripeptide-5 and Nonapeptide-1, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. Cell Fusion C sells this Niacinamide ampoule in Korea, and this is that version.

Key actives

5Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this ampoule's own ingredient list it is named fifth.

All products with Niacinamide

20Adenosineactive

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 twentieth on this ampoule's list, beside Niacinamide.

All products with Adenosine

29Palmitoyl Tripeptide-5peptide

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. It is named twenty-ninth on this ampoule's list, alongside Niacinamide.

All products with Palmitoyl Tripeptide-5

31Nonapeptide-1peptide

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. The panel names it thirty-first on this ampoule's list, beside Niacinamide.

All products with Nonapeptide-1

33Acetyl Hexapeptide-8peptide

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. It is named thirty-third on this ampoule's list, alongside Niacinamide.

47 of 50 explained

Purified 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.
Methylpropanediol humectant: Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
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.
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.
Niacinamide active: Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
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.
Polyglycerin-3 humectant: Polyglycerin-3 is a short chain of glycerin units used as a gentler, less sticky humectant. It also helps oils and water stay blended.
Centella Asiatica Extract plant extract: Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
Avena Sativa (Oat) Kernel Extract plant extract: Oat Kernel Extract carries beta-glucan and avenanthramides, and it is one of the most reliably tolerated ingredients in skincare. It is used for the look of reddened, itchy-feeling skin.
Pteris Multifida Extract plant extract: Spider brake fern extract, a traditional East Asian herbal plant. It is used as a conditioning extract.
Cynara Scolymus (Artichoke) Leaf Extract plant extract: Artichoke Leaf Extract carries cynaropicrin and other plant antioxidants. It is used in formulas aimed at the look of visible pores and dullness.
Vigna Radiata Seed Extract plant extract: Mung bean seed extract, the nokdu of Korean cleansing powders. It carries starches, proteins and saponins and is used as a conditioning, mildly cleansing extract.

35 more explained

Persea Gratissima (Avocado) Fruit Extract plant extract: Avocado fruit extract, the water-soluble fraction rather than the pressed oil. It is used as a conditioning extract.
Sodium Hyaluronate humectant: Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
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.
Cyclohexasiloxane silicone: Cyclohexasiloxane is a volatile silicone used for a light, fast-spreading feel that leaves nothing behind.
Ammonium Acryloyldimethyltaurate/VP Copolymer thickener: This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
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.
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.
Carbomer thickener: Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
Disodium EDTA chelator: EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
Tromethamine pH adjuster: Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
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.
Beta-Glucan polysaccharide: Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
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.
Hydrolyzed Collagen protein: Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
Aureobasidium Pullulans Ferment ferment: A ferment of the yeast-like fungus that pullulan is made from. It yields water-holding beta-glucans and is used as a conditioning ferment.
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.
Hydrolyzed Lupine Protein protein: Hydrolyzed Lupine Protein comes from the lupin bean, which is unusually protein rich. Hydrolysed, it dissolves and works as a conditioning, water-holding protein.
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.
Maltodextrin film former: Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
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.
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 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.
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.
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.
Hydrolyzed Hyaluronic Acid humectant: Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
Hyaluronic Acid humectant: Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
Sodium Acetylated Hyaluronate humectant: Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
Hydroxypropyltrimonium Hyaluronate humectant: Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
Potassium Hyaluronate humectant: Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.
Aroma fragrance: Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
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.
Caprylyl Glycol preservative booster: Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.

How to use

Apply after toner and before moisturizer. Pat or smooth it over a cleansed face and let it absorb before the next step, AM and PM.

Worth knowing

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