Centellian24 Madeca TECA RETINOLSOM 0.2 Firming Serum 30ml
What does the Madeca TECA RETINOLSOM 0.2 Firming Serum 30ml actually do?
It sits in the line for serum work rather than a single fast fix. Squalane is an emollient that sits close to skin's own lipids and Panthenol is a comfort ingredient for softness. This product works best as a treatment step after toner and before moisturizer rather than as a stand-alone fix.
Is this suitable for sensitive or reactive skin?
Centellian24 positions its skincare line around barrier support and comfort rather than aggressive actives, and sensitive-leaning or redness-prone skin is the audience that positioning targets. Anyone new to an ingredient on this formula's list still does well to patch test on the inner arm first and build up frequency slowly.
How long before I notice a difference with the Madeca TECA RETINOLSOM 0.2 Firming Serum 30ml?
Surface-level changes such as texture and softness tend to show first, usually within a couple of weeks of consistent use. Anything tied to tone or firmness takes longer to become visible because it builds with repeated use rather than a single application. Results depend on keeping the step in the routine; skipping it for stretches of time slows how quickly a difference shows.
Can this be layered with the rest of a routine?
It layers easily after toner and before a moisturizer. Introducing any new treatment step one at a time, rather than several at once, makes it easier to tell what a change in the skin is actually responding to.

80 of 84 explained
- 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.
- Squalane emollient
- Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
- Vinyl Dimethicone silicone
- Vinyl Dimethicone is a silicone used as a building block of the crosspolymer gels that give a formula its soft, blurring feel.
- 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.
- Dimer Dilinoleyl Dimer Dilinoleate emollient
- A very large plant-derived ester with a heavy, cushioned feel. It is used in lip and balm formulas for gloss and cling.
- C12-15 Alkyl Benzoate emollient
- C12-15 Alkyl Benzoate is a light ester emollient and solvent. It gives a silky finish, dissolves pigments and UV filters, and mildly discourages microbial growth.
- 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.
- 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.
- Zea Mays (Corn) Starch absorbent
- Corn Starch absorbs oil and moisture and gives a soft, matte finish. It also thickens a formula.
- 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.
- Microcrystalline Cellulose absorbent
- Microcrystalline Cellulose is purified cellulose ground fine. It thickens, holds powders in suspension and gives a soft, matte feel.
- Isopropyl Myristate emollient
- Isopropyl Myristate is a light ester emollient that absorbs fast and helps other ingredients penetrate. It is known to be poorly suited to blemish-prone skin at higher levels.
68 more explained
- 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.
- 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.
- Polyglyceryl-4 Laurate emulsifier
- A short polyglycerin ester used as a mild emulsifier and cleansing agent. It is common in balms designed to melt on skin and then rinse away.
- Polyglyceryl-6 Laurate emulsifier
- Six glycerin units joined to lauric acid. Polyglyceryl esters are the mild, PEG-free way to hold oil and water together.
- Cetearyl Glucoside emulsifier
- Cetearyl Glucoside is a sugar-derived emulsifier used to hold oil and water together in creams with a light finish.
- 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.
- 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.
- Bakuchiol active
- Bakuchiol is a compound from the babchi seed, used as a plant-derived alternative to retinol. It is oil soluble, stable in daylight and does not carry retinol's acclimatisation period, which is why sensitive-skin formulas choose it.
- 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.
- 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.
- Sorbitan Olivate emulsifier
- Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
- Glyceryl Glucoside humectant
- Glyceryl Glucoside is glycerin bound to glucose, from the resurrection plant. It is a humectant that holds water in the outer layer of skin.
- 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.
- 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.
- Coptis Japonica Root Extract plant extract
- Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin.
- Hydroxypropyl Starch Phosphate thickener
- Hydroxypropyl Starch Phosphate is a modified starch used to thicken and to take the sticky edge off a formula, leaving a powdery finish.
- 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.
- 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.
- Cetearyl Alcohol fatty alcohol
- Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
- Ceramide NP barrier lipid
- Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
- 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.
- Nicotinamide Mononucleotide active
- Nicotinamide Mononucleotide is a nucleotide built from vitamin B3 and a sugar phosphate. Korean formulas use it as a conditioning active, usually alongside niacinamide itself.
- 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.
- Centella Asiatica Leaf Water plant extract
- Centella Asiatica Leaf Water is the distilled water of the centella leaf, used in place of plain water as a formula base. It is far more dilute than the extract, so it sets the base rather than supplying the actives.
- Hydrogenated Phosphatidylcholine emulsifier
- Hydrogenated Phosphatidylcholine is the stabilised form of the main lecithin phospholipid. It builds the liposome shells that hold an active together in a formula.
- 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.
- Madecassic Acid active
- Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
- Asiaticoside active
- Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
- Asiatic Acid active
- Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
- 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.
- Saccharomyces/Viscum Album Ferment Extract ferment
- Mistletoe fermented with yeast, then extracted. Fermentation breaks the plant material down into smaller sugars and peptides, and the extract is used as a conditioning ferment.
- 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/Imperata Cylindrica Root Ferment Extract ferment
- Cogon grass root fermented with yeast, then extracted. The root is used in formulas for its water holding sugars and potassium, and fermentation makes them more available.
- Coffea Arabica Seed Extract plant extract
- Coffee Seed Extract carries caffeine and chlorogenic acid. It is used as an antioxidant extract and, in eye and body formulas, for the look of puffiness.
- 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.
- Anemarrhena Asphodeloides Root Extract plant extract
- Anemarrhena Asphodeloides is a root used in Korean traditional practice. Its extract is used as a conditioning plant extract.
- 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.
- Polyglyceryl-3 Methylglucose Distearate emulsifier
- Polyglyceryl-3 Methylglucose Distearate is a sugar-derived emulsifier known for a light, non-soapy feel. It builds gel-creams that do not read as rich.
- Dimethylsilanol Hyaluronate humectant
- Dimethylsilanol Hyaluronate is hyaluronic acid joined to a silicon-based group. It hydrates and leaves a smoother, silkier finish than hyaluronic acid alone.
- Hydrolyzed Sodium Hyaluronate 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.
- Hyaluronic Acid humectant
- Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
- 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.
- Phytosphingosine barrier lipid
- Phytosphingosine is the backbone every ceramide is built on, and skin uses it in its own lipid layer. In a formula it works with ceramides and cholesterol and also keeps the product stable against microbes.
- Soluble Collagen protein
- Soluble Collagen is collagen kept in its intact triple-helix form and dissolved rather than cut up. It sits on the surface as a water-holding film.
- Potassium Hyaluronate humectant
- Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
- 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.
- Sodium Hyaluronate Crosspolymer humectant
- Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
- Hydroxypropyltrimonium Hyaluronate humectant
- Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
- Ceramide NG barrier lipid
- One of the ceramide types found between skin cells, also written ceramide 2. Ceramides are the lipid that fills the space between cells in the outer layer.
- Ceramide NS barrier lipid
- Ceramide NS is another of the ceramides skin makes for itself. It is used alongside NP and AP so a formula supplies a mixture rather than a single lipid.
- Ceramide AS barrier lipid
- Ceramide AS is a further member of the same lipid family. Its presence usually signals a formula built around a full ceramide profile rather than a single headline one.
- Ceramide AP barrier lipid
- Ceramide AP is a second cosmetic ceramide, distinguished by an extra hydroxyl group. Formulas that name several ceramides are copying the mix skin actually holds rather than relying on one.
- 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.
- 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.
- 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.
- Sodium Acetylated Hyaluronate humectant
- Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
- 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.
- Paeonia Albiflora Flower Extract plant extract
- White peony flower extract, from the same plant also written Paeonia lactiflora. The flower carries flavonoids and tannins and is used as a conditioning botanical.
- Nymphaea Caerulea Flower Extract plant extract
- Blue lotus flower extract. It carries flavonoids and mucilage, so it acts as a conditioning botanical and contributes a little water holding body.
- Sophora Japonica Flower Extract plant extract
- Pagoda tree flower extract, the richest plant source of rutin. It is used as a plant antioxidant.
- Centaurea Cyanus Flower Extract plant extract
- Cornflower extract, a traditional eye-area ingredient in European pharmacy. It carries flavonoids and anthocyanins and is used in gentle formulas.
- Crocus Sativus Flower Extract plant extract
- Saffron crocus flower extract, from the same flower the spice is picked from. It carries carotenoids and is used as a conditioning antioxidant extract.
- Retinal active
- Retinal is retinaldehyde, a vitamin A derivative one chemical step closer to retinoic acid than retinol is. It is yellow-orange and unstable in light, so products carrying it are usually opaque.
- Retinyl Palmitate active
- Retinyl Palmitate is retinol bound to a fatty acid. It is the mildest common retinoid because skin has to make three conversions before it becomes active, which also makes it the least likely to cause flaking.
- Hydroxypinacolone Retinoate active
- Hydroxypinacolone Retinoate is a retinoid ester that binds skin's retinoid receptors directly, with no conversion step. Brands use it where they want retinoid-style results with less of the flaking retinol brings.
- Ceramide EOP barrier lipid
- Ceramide EOP is the ceramide with the longest tail, and in skin it acts as the rivet holding the lipid layers together. It is the third member of the standard cosmetic ceramide trio.

How it works
This serum sits in Centellian24's centella-based range, built around the ingredients printed on its own box rather than a single headline claim. Squalane is an emollient that sits close to skin's own lipids. Panthenol is a comfort ingredient for softness. Bakuchiol rounds out the formula as a plant-derived alternative to retinol. In use, it works as a treatment step after toner and before moisturizer. Give the formula a few weeks in the routine before judging it, and adjust frequency to how skin responds rather than a fixed schedule.
How to use
- Use it in the evening only, after toner and before moisturizer.
- A pea sized amount for the whole face, kept away from the eye area.
- Follow with a moisturizer, because a retinoid step is easier on skin under a seal.
- Do not use it with an acid or another retinoid in the same routine.
Worth knowing
- New to this formula: patch-test on the inner arm and wait a day before applying it to the face.
- Discontinue use if redness, itching, or irritation develops and rinse the area with water.
- A retinoid can increase sun sensitivity, so pair daytime use with a separate sunscreen step.
