Belif
Youth Creator Age Knockdown Eye Serum 25ml
Belif puts palm oil, shea butter and macadamia oil fifth, sixth and seventh on this 25 ml eye serum's 62 entry list, so it is richer than the word serum suggests, with oat kernel, calendula, chickweed, licorice root and rhodiola rosea running through the middle.

How to use
- Use the Youth Creator Age Knockdown Eye Serum after toner and before your eye cream or moisturizer, morning and evening.
- Apply an appropriate amount around the eyes before moisturizer or cream. Gently smooth from the inner to the outer eye area, including the eyelids and eye bones, then pat lightly until absorbed. Use morning and evening.
- It goes under the richer layers, so eye cream or moisturizer follows it once it has settled.
- Twice a day. Do not press the applicator into the lash line or the waterline; the orbital bone is the closest it belongs.
Does this product contain added fragrance?
No. Neither fragrance nor parfum appears on the ingredient list for Belif Youth Creator Age Knockdown Eye Serum 25ml. Those are the two names a cosmetic label uses for an added scent blend, so a formula carrying one would name it. The full list is printed in the Ingredients section of this page.
Does this product contain essential oils?
Yes. The ingredient list for Belif Youth Creator Age Knockdown Eye Serum 25ml includes Citrus Aurantium Dulcis (Orange) Peel Oil, Pelargonium Graveolens Flower Oil and Rosmarinus Officinalis (Rosemary) Leaf Oil. Aromatic plant oils are listed under their botanical name rather than as fragrance, so they are named separately from any fragrance or parfum entry.
Are any declarable fragrance allergens listed?
Yes. Limonene, Citronellol, Geraniol, Citral and Linalool appear on the ingredient list for Belif Youth Creator Age Knockdown Eye Serum 25ml. These belong to the 26 fragrance components that EU cosmetic labelling requires to be named individually rather than folded into a fragrance entry.
Does this product contain denatured or SD alcohol?
No. The ingredient list for Belif Youth Creator Age Knockdown Eye Serum 25ml names no denatured alcohol, SD alcohol or ethanol. Fatty alcohols such as cetyl and cetearyl alcohol are a different class of ingredient, used as emollients and thickeners, and are not counted here.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, silicones, parabens, sulfate surfactants and mineral oil or petrolatum.

50 of 62 explained
- Water/Aqua/Eau 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.
- 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.
- 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.
- 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.
- Elaeis Guineensis (Palm) Oil emollient
- Palm Oil is a rich emollient high in palmitic and oleic acids. In skincare it is more often a source material for esters and emulsifiers than an ingredient on its own.
- Butyrospermum Parkii (Shea) Butter emollient
- Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
- Macadamia Ternifolia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
- 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.
- 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.
- Elaeis Guineensis (Palm) Kernel Oil emollient
- Palm kernel oil, high in lauric acid and solid at room temperature. It gives balms and cleansing bases their body.
- Behenyl Alcohol fatty alcohol
- Behenyl Alcohol is a long-chain fatty alcohol used to thicken and stabilise a cream. It gives a richer, more velvety body than cetyl alcohol.
- 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.
38 more explained
- Calendula Officinalis Flower Extract plant extract
- Marigold flower extract, one of the oldest plant ingredients used for the look of reddened, easily bothered skin. It carries carotenoids and flavonoids.
- Stellaria Media (Chickweed) Extract plant extract
- Chickweed extract, a common garden herb used for the look of reddened, easily bothered skin. It carries saponins and mucilage.
- Glycyrrhiza Glabra (Licorice) Root Extract plant extract
- Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.
- Rhodiola Rosea Root Extract plant extract
- Roseroot extract, from an arctic and alpine plant. It carries salidroside and is used as an antioxidant conditioning extract.
- Vaccinium Myrtillus Fruit Extract plant extract
- Bilberry fruit extract, the European relative of the blueberry and one of the richest anthocyanin sources. It is used as a plant antioxidant.
- Lupinus Albus Seed Extract plant extract
- White lupin seed extract, a legume extract carrying proteins and peptides. It is used as a conditioning extract.
- Caprylic/Capric Glycerides emollient
- The partial glycerides of the same short coconut fatty acids used to make caprylic/capric triglyceride. They are lighter than the triglyceride and help dissolve actives.
- 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.
- 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.
- 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.
- 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.
- 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.
- Glycine Soja (Soybean) Seed Extract plant extract
- Soybean Seed Extract carries isoflavones, plant sterols and soy proteins. It is used as a conditioning antioxidant extract.
- 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.
- Lactobacillus/Soybean Ferment Extract ferment
- This is soybean fermented by lactobacillus. The fermentation breaks soy proteins into smaller pieces, which is what makes the extract easier for a formula to carry.
- Saccharomyces/Potato Extract Ferment Filtrate ferment
- Potato extract fermented with yeast and strained. It supplies sugars and amino acids and is used as a conditioning ferment.
- Sodium Polyacrylate thickener
- Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
- Saccharomyces/Barley Seed Ferment Filtrate ferment
- Barley fermented with brewing yeast and strained clear. Fermentation breaks the grain starch and protein into sugars, peptides and B vitamins that hold water.
- Serine amino acid
- Serine is one of the most abundant free amino acids in the outer layer of skin, where it helps hold water. Added to a formula it is a humectant.
- 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.
- Helianthus Annuus (Sunflower) Seed Oil emollient
- Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
- 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.
- 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.
- Centella Asiatica Leaf 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.
- Salicornia Herbacea Extract plant extract
- Glasswort, the hamcho that grows on Korean tidal flats. It concentrates sea minerals as it grows, so its extract is used as a mineral-rich hydrating ingredient.
- 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.
- Palmitic Acid fatty acid
- Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
- Stearic Acid fatty acid
- Stearic Acid is a saturated fatty acid from plant fats, and one of the three lipid classes skin's own barrier is built from. In a formula it thickens, stabilises the emulsion and can be turned into a soap-style cleanser by adding a base.
- Mica colorant
- Mica is a mineral ground into fine flakes. It scatters light, so it lightens a shade and gives the soft glow of a tinted or illuminating product.
- Citrus Aurantium Dulcis (Orange) Peel Oil fragrance component
- Sweet Orange Peel Oil is a citrus essential oil carrying limonene. It scents a formula, and limonene is one of the components EU labelling names separately.
- Citrus Aurantifolia (Lime) Oil fragrance component
- Lime oil, an essential oil pressed from the peel. It scents a formula strongly, and expressed citrus oils can make skin more sensitive to sun.
- 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.
- Rosmarinus Officinalis (Rosemary) Leaf Oil fragrance component
- Rosemary Leaf Oil is an essential oil carrying camphor and cineole. It scents a formula and is a stronger aromatic than most.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- Geraniol fragrance component
- Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
- Citral fragrance component
- Citral is a sharp lemon aromatic found in lemongrass and citrus oils. It is one of the 26 fragrance components EU labelling requires to be named.
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.
