How it works
The To Be Youthful Eye Serum is a 25ml eye serum, used after toner and before your eye cream or moisturizer, morning and evening. The active it is built around is Niacinamide, named sixth on its own ingredient list. The same list carries Adenosine, Tocopherol and Hydrolyzed Vegetable Protein, 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 eye serum format rather than by the list alone. Dr.Althea sells this Niacinamide eye serum in Korea, and this is that version.
Key benefits
- Niacinamide, the active this eye serum is built around
- Adenosine on the same list, an active
- Tocopherol on the same list, an antioxidant
- Hydrolyzed Vegetable Protein on the same list, a protein
- Laminaria Japonica Extract and Eclipta Prostrata Extract further down the same list
- Anastatica Hierochuntica Extract and Persea Gratissima (Avocado) Oil further down the same list
Inside the formula
Inside the formula
Where does this eye serum go in my routine?
After toner and before your eye cream or moisturizer, morning and evening. Anything thinner than an eye 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 Niacinamide and not three changes at once.
Does this eye serum contain fragrance?
Yes. The ingredient list names Fragrance. It sits on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this eye serum is not the one.
What else is on the list besides Niacinamide?
Adenosine, Tocopherol and Hydrolyzed Vegetable Protein. The order they are printed in on this eye serum's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Beta-Glucan, Laminaria Japonica Extract and Eclipta Prostrata Extract.
Not on the ingredient list below: denatured or SD alcohol, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

39 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.
- Cyclohexasiloxane silicone
- Cyclohexasiloxane is a volatile silicone used for a light, fast-spreading feel that leaves nothing behind.
- 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.
- 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.
- Raffinose sugar
- Raffinose is a three-unit plant sugar found in beans and beetroot. It holds water in the outer layer of skin and helps a formula stay comfortable as it dries down.
- Phenyl Trimethicone silicone
- Phenyl Trimethicone is a silicone with a higher refractive index than most, so it adds visible gloss as well as slip. It is common in glow and lip textures.
- Laminaria Japonica Extract plant extract
- Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
- Eclipta Prostrata Leaf 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.
- Anastatica Hierochuntica Extract plant extract
- Anastatica Hierochuntica is the resurrection plant, which survives complete drying out. Its extract is used as a hydrating, protective plant ingredient.
- 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.
- 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.
27 more explained
- Persea Gratissima (Avocado) Oil emollient
- Avocado oil, rich in oleic acid and plant sterols. It is one of the heavier plant oils, which suits dry skin and cleansing balms.
- Lavandula Angustifolia (Lavender) Oil fragrance component
- Lavender Oil is an essential oil carrying linalool and linalyl acetate. It scents a formula, and linalool is one of the fragrance components EU labelling requires to be named separately.
- Dimethicone/Vinyl Dimethicone Crosspolymer silicone
- This is a silicone elastomer, a soft springy gel. It fills the look of fine texture and gives the velvety, blurred finish of a primer.
- 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.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener
- This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
- Polyglyceryl-3 Polydimethylsiloxyethyl Dimethicone emulsifier
- A silicone emulsifier with polyglycerin attached. It is the standard way to hold water inside a silicone fluid, which is how many mineral sun fluids are built.
- 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.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
- Polyacrylate-13 thickener
- Polyacrylate-13 is a pre-neutralised thickener that gels instantly and holds an emulsion together, so a formula can be built without heat.
- Hydrogenated Polyisobutene emollient
- Hydrogenated Polyisobutene is a stabilised synthetic hydrocarbon used in place of mineral oil. It is an emollient that leaves a smooth, cushioned film.
- 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.
- 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.
- Fructooligosaccharides humectant
- Fructooligosaccharides are short fructose chains used as humectants and as food for the skin's own resident microbes.
- Ethylhexyl Palmitate emollient
- Ethylhexyl Palmitate is a palm-derived ester used as a light emollient and a solvent for pigment. It gives a smooth, non-greasy slip.
- 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.
- Sorbitan Isostearate emulsifier
- Sorbitan Isostearate is a mild emulsifier that holds water into oil, the direction a cleansing balm or an oil-based cream needs.
- 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.
- Sodium Laurate surfactant
- The soap of lauric acid. Soap-based cleansers foam densely and sit at a high pH, which is the traditional Korean foaming-cleanser route rather than the low-pH one.
- Lauric Acid fatty acid
- Lauric Acid is the coconut fatty acid that gives soap-style cleansers their dense foam. It is not well suited to blemish-prone skin at high levels.
- 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.
- 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.
- 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.
- Hydrolyzed Vegetable Protein protein
- Hydrolyzed Vegetable Protein is plant protein cut into water-soluble fragments. It forms a light conditioning film that holds water at the surface.
- 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.
- Fragrance 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.
- 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.
- 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.
