Key benefits
- Retinol named on this product's own ingredient panel

- Korean-market formula, with its Korean barcode and batch code intact on the box
Key actives
3Niacinamide
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.
5Chondrus Crispus Powder
Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
10Calcium Chloride
Calcium Chloride is a mineral salt used in traces to balance a formula and to firm up gels made with alginate or gellan gum.
41Retinol
Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises.

38 of 41 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.
- 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.
- 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.
- Chondrus Crispus Powder plant extract
- Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
- Glucomannan thickener
- Glucomannan is a konjac root polysaccharide. It thickens, holds a great deal of water and leaves a smooth, cushioned film.
- 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.
- 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.
- Calcium Chloride mineral
- Calcium Chloride is a mineral salt used in traces to balance a formula and to firm up gels made with alginate or gellan gum.
- 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.
- Isononyl Isononanoate emollient
- Isononyl Isononanoate is a branched ester used as a dry emollient. It spreads far for its weight and leaves almost no residue, which is why it appears in formulas that have to feel weightless.
- Ceratonia Siliqua Gum thickener
- Carob Gum is a seed polysaccharide from the carob tree. It thickens a formula and gives a soft, cushioned body.
26 more explained
- Boron Nitride absorbent
- A plate-like mineral powder with a notably slippery feel. It softens how light falls on skin and makes a powder or stick glide rather than drag.
- 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.
- Potassium Chloride mineral
- Potassium Chloride is a mineral salt used to bring a formula closer to the salt balance of skin, most often as part of a sea-water or mineral-water blend.
- Allantoin active
- Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
- Sucrose humectant
- Sucrose is table sugar, used here as a humectant. It draws water into the outer layer of skin and, in a scrub, doubles as the physical grain.
- 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.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- Hydrolyzed Extensin protein
- Extensin is a structural glycoprotein from plant cell walls. Hydrolysed, it is cut into fragments small enough to dissolve, and it works as a water-holding film on the surface.
- 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.
- 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.
- Gellan Gum thickener
- Gellan Gum is a fermentation-derived polysaccharide that sets a clear, brittle gel at very low levels. It is used to suspend particles without thickening the liquid much.
- Agar thickener
- Agar is a seaweed polysaccharide that sets into a firm gel. It is the gelling agent behind jelly masks and thick sleeping packs.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Sodium Phytate chelator
- Sodium Phytate is a rice-derived chelator used in place of EDTA. It ties up trace metals so the formula stays stable and its colour and scent hold.
- Caffeine active
- Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the skin.
- Eclipta Prostrata Extract plant extract
- Eclipta Prostrata is false daisy, long used in Ayurvedic and East Asian practice. Its extract is used as a conditioning plant extract, most often in scalp and hair formulas.
- Iron Oxides (CI 77491) colorant
- Iron Oxides are mineral pigments in red, yellow and black, and the three are blended to make every skin-tone shade in a tinted product. They are inert and sit on the surface.
- Pelargonium Graveolens Flower Oil fragrance component
- Pelargonium Graveolens is rose geranium. Its flower oil is an essential oil used to scent a formula, carrying citronellol and geraniol.
- Melia Azadirachta Leaf Extract plant extract
- Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin.
- 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.
- Moringa Oleifera Seed Oil emollient
- Moringa Seed Oil is high in oleic acid and behenic acid and very stable. It is a conditioning emollient with a light, non-sticky finish.
- Rosa Damascena Flower Extract plant extract
- Damask rose flower extract, the rose grown for perfume. It carries tannins and flavonoids and is used as a conditioning extract.
- Sodium DNA active
- 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.
- Retinol active
- Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises.

How it works
Retinol is named on the ingredient panel on this formula. Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises. On this panel it sits alongside Niacinamide, Chondrus Crispus Powder and Calcium Chloride. 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.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Vitamin A has a molecular structure that's tiny enough to get into the lower layers of your skin, where it finds and boosts collagen and elastin, which is a protein that strengthens your skin's flexibility.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
