How it works
VITA TINOL SERUM 30g is a serum built on Ascorbic Acid, pure vitamin C, the most active but least stable form used, named 10 of 50 entries on primera's own manufacturer INCI for this formula. 3-O-Ethyl Ascorbic Acid runs alongside it, a stabilized vitamin C derivative, and the rest of the list rounds out a primera formula built for this format rather than a stripped-down version of it. It takes after toner and before moisturizer, and the serum format is the reason it behaves the way it does once it is on skin. A serum in this format is built to carry a concentrated dose of its named actives in a light enough base that it absorbs before the next step goes on.

Inside the formula
Inside the formula
Is the VITA TINOL SERUM 30g sold here primera's Korean-market formula?
Yes. What ships is primera's release for the Korean market: the formula and packaging sold in Korea, with the Korean-market barcode and batch code intact on the box rather than swapped for an export or US-retail label.
Where does the VITA TINOL SERUM 30g go in a routine?
It takes after toner and before moisturizer. Use it exactly the way you would any serum at that point in a routine. A serum in this format is built to carry a concentrated dose of its named actives in a light enough base that it absorbs before the next step goes on, which is the reason this step order tends to hold across brands, not only for this one.
What does Ascorbic Acid do in this serum?
Ascorbic Acid is Pure vitamin C, the most active but least stable form used. It appears at position 10 of 50 on primera's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Does the VITA TINOL SERUM 30g contain fragrance?
Yes. Parfum appears on the manufacturer's own ingredient list for this formula, contributing to its scent alongside the actives above. If a fragrance-free routine matters to you, check the position of parfum on the full list before buying.
How does buying the VITA TINOL SERUM 30g here compare with a US retailer carrying the same name?
A US listing under the same product name can be a reformulated export version and rarely states which one it is selling. What we carry is the Korean-market primera release, identified by its intact Korean barcode and batch code on the box rather than a relabeled export carton, so the unit you get matches what is sold on shelf in Korea.

Ingredient list read from inkeedecoder.com on 10 September 2026.
45 of 49 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.
- 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.
- 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.
- 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.
- Caprylyl Methicone silicone
- Caprylyl Methicone is a silicone with a fatty tail, so it mixes with plant oils as well as with silicones. It gives a dry slip and helps disperse powders.
- 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.
- 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.
- Ascorbic Acid antioxidant
- Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone.
- 3-O-Ethyl Ascorbic Acid antioxidant
- 3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable.
- Polysorbate 20 emulsifier
- Polysorbate 20 is a solubiliser: it dissolves small amounts of oil or fragrance into a watery formula so nothing separates or floats.
- Dimethicone silicone
- Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.
- 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.
33 more explained
- Lactobacillus Ferment Lysate ferment
- Lactobacillus Ferment Lysate is the ferment with the bacterial cells broken open, so their contents are in the formula too. It is a conditioning ferment used in barrier-focused products.
- Mannitol humectant
- Mannitol is a sugar alcohol used as a humectant and antioxidant. It hydrates and helps stabilise the rest of the formula against oxidation.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
- 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.
- Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is the thickener behind most gel-cream textures. It builds a soft, bouncy gel that collapses to a light fluid as it is rubbed in.
- Polyisobutene film former
- Polyisobutene is a synthetic polymer that forms a flexible, water-resistant film. It gives gloss and holds a formula in place, which is why it appears in lip products and long-wear textures.
- Sodium Citrate pH adjuster
- Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.
- 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.
- Sodium Polyacryloyldimethyl Taurate thickener
- Sodium Polyacryloyldimethyl Taurate is a polymer thickener that holds a gel stable even with a lot of salt or acid in the formula.
- Polymethyl Methacrylate absorbent
- Polymethyl Methacrylate is an acrylic polymer used as fine spheres. They give a smooth, powdery slip and blur the look of surface texture.
- 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.
- Glycine Soja (Soybean) Oil emollient
- Soybean Oil is a linoleic-rich plant oil used as an emollient. It also carries soy phytosterols and vitamin E.
- 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.
- Glyceryl Caprylate emulsifier
- Glyceryl Caprylate is a mild emulsifier that also makes a formula less hospitable to microbes, so it is often part of a preservative-free system.
- Carnosine antioxidant
- Carnosine is a small peptide of two amino acids that acts as an antioxidant, particularly against the sugar-driven damage formulators call glycation. It is used for the look of dull, sallow skin.
- 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.
- 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.
- 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.
- Thymol Trimethoxycinnamate antioxidant
- Thymol, the phenol from thyme, joined to a cinnamic acid ester. The ester form is oil soluble and stable, and it is used as an antioxidant.
- 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.
- 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.
- 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.
- Glycine Max (Soybean) Polypeptide protein
- Soy protein cut into shorter polypeptide chains. The smaller chains dissolve in water and are used as a conditioning protein that leaves a smooth film.
- 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.
- Phospholipids barrier lipid
- Phospholipids are the lipid class lecithin belongs to, with a water friendly head and two fatty tails. That shape is what lets them form liposomes and hold an emulsion together.
- 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.
- Theobroma Cacao (Cocoa) Seed Extract plant extract
- Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
- BHT antioxidant
- BHT is a synthetic antioxidant used in traces to stop the oils in a formula going rancid. It protects the product, not the skin.
- Gardenia Florida Fruit Extract plant extract
- Gardenia Fruit Extract is the traditional East Asian yellow dye plant. In skincare it is used as an antioxidant extract, and it can tint a formula.
- Papain exfoliant
- Papain is a protein-cutting enzyme from papaya. Enzyme exfoliants act on protein rather than on the bonds an acid targets, and they need water to work, which is why they suit powder washes.
- Pearl Powder protein
- Pearl Extract is ground pearl treated so its calcium carbonate and protein fractions disperse. It is used as a mineral-and-protein conditioning ingredient with a faint light-scattering effect.
- Sodium Polyphosphate chelator
- Sodium Polyphosphate is a chain phosphate salt that ties up metal ions. That keeps a formula stable and stops hard water flattening a cleanser foam.
- 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.

How to use
- Apply after the toner while the skin is still damp so a small dose covers the face in one pass.
- Press it in with the flats of the fingers rather than rubbing it around in circles.
- Always follow with a cream, since a concentrated layer left unsealed is where tightness comes from.
- Do not use more than the face absorbs in half a minute, because the excess ends up on your collar rather than working.
Worth knowing
- A vitamin C formula: patch test first if skin is currently reactive, and introduce it gradually.
- Discontinue if irritation develops and check the ingredient list against any known sensitivity.
