How it works
The Closer Pore Reducing Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Adenosine, named sixteenth on its own ingredient list. The same list carries Gluconolactone, Acetyl Hexapeptide-8 and Tripeptide-3, so the active is not the only thing on it worth naming. How much of the Adenosine stays on the skin, and for how long, is decided by the serum format rather than by the list alone. Frankly sells this Adenosine serum in Korea, and this is that version.
Key benefits
- Adenosine, the active this serum is built around
- Gluconolactone on the same list, an exfoliant
- Acetyl Hexapeptide-8, Tripeptide-3 and Acetyl Octapeptide-3 on the same list, peptides
- Copper Tripeptide-1 and Palmitoyl Pentapeptide-4 further down the same list
- Palmitoyl Tetrapeptide-7 and Palmitoyl Tripeptide-1 further down the same list
- Adenosine named sixteenth on the manufacturer list printed on this page
Key actives
7Acetyl 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. The panel names it seventh on this serum's list, beside Adenosine.
8Tripeptide-3peptide
Tripeptide-3 is a three-amino-acid peptide used in multi-peptide blends. It turns up in hair and scalp formulas as often as in facial ones. It is named eighth on this serum's list, alongside Adenosine.
9Acetyl Octapeptide-3peptide
Acetyl Octapeptide-3 is an eight-amino-acid peptide used for the look of expression lines. It is usually paired with acetyl hexapeptide-8 rather than used alone. It is named ninth on this serum's list, alongside Adenosine.
16Adenosineactive
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. On this serum's own ingredient list it is named sixteenth.
17Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. The panel names it seventeenth on this serum's list, beside Adenosine.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum 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 Adenosine and not three changes at once.
What else is on the list besides Adenosine?
Gluconolactone, Acetyl Hexapeptide-8 and Tripeptide-3. The order they are printed in on this serum's panel is the order on the box, so you can see where Adenosine sits relative to them. Further down the same panel: Acetyl Octapeptide-3, Copper Tripeptide-1 and Palmitoyl Pentapeptide-4.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

32 of 32 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.
- 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.
- 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.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- 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.
- 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.
- 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.
- Tripeptide-3 peptide
- Tripeptide-3 is a three-amino-acid peptide used in multi-peptide blends. It turns up in hair and scalp formulas as often as in facial ones.
- Acetyl Octapeptide-3 peptide
- Acetyl Octapeptide-3 is an eight-amino-acid peptide used for the look of expression lines. It is usually paired with acetyl hexapeptide-8 rather than used alone.
- 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.
- 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 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.
20 more explained
- 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.
- 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.
- Tripeptide-2 peptide
- Tripeptide-2 is a peptide of three amino acids. The number after the name identifies one specific sequence rather than a strength, and it is used in blends for the look of firmness.
- 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.
- Gluconolactone exfoliant
- Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
- Collagen protein
- Collagen is the structural protein that makes up most of the dermis. Applied on top it is far too large to enter skin, so in a formula it works as a humectant and a smoothing film former.
- 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.
- Leuconostoc/Radish Root Ferment Filtrate preservative
- This is radish root fermented by Leuconostoc, the culture behind kimchi, then filtered clear. It carries natural antimicrobial peptides, so formulas use it in place of part of a conventional preservative.
- 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.
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- 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.
- Cellulose Gum thickener
- Cellulose Gum is plant cellulose modified to dissolve in water. It thickens, holds particles in suspension and gives a smooth, slippery body.
- 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.
- 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.
- 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.
- 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.
- Hydrolyzed Gardenia Florida Extract plant extract
- Hydrolyzed Gardenia Florida Extract is gardenia extract broken into smaller fragments so a water-based formula can carry it evenly.
- Hydrolyzed Malt Extract plant extract
- Malt extract with its sugars and proteins already broken into smaller pieces. It is used as a hydrating, conditioning extract.
- Hydrolyzed Viola Tricolor Extract plant extract
- Heartsease, the wild pansy, with its extract broken into smaller fragments. It is used as a conditioning plant extract.
- 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.

How to use
- Apply a few drops to clean skin after toner or essence and before moisturizer, morning and/or night, pressing it in rather than rubbing.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Adenosine on the list.
- Gluconolactone on this list makes this serum an exfoliating step, so do not stack it with another one on the same night.

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.
