What is Deep Cera Bakuchiol Plumping Serum?

It is EQQUALBERRY's ampoule serum (30ml). Its own ingredient list names Niacinamide, Bakuchiol, Ceramide NP, Hydroxyethyl Urea, positioned the way the key-actives panel on this page describes, rather than actives assumed from the product name. It is used after toner and before moisturizer, as the routine's concentrated treatment step.

How do I use Deep Cera Bakuchiol Plumping Serum?

Apply after toner and before moisturizer. Pat or smooth it over a cleansed face and let it absorb before the next step, AM and PM. Keep the same order every time you use it so you can tell what is actually working, and give a new step a few weeks before judging the result.

Is Deep Cera Bakuchiol Plumping Serum the authentic Korean-market formula?

Yes. This listing is EQQUALBERRY's Korean-market formula: the same ingredient list, barcode and batch code as the unit sold on shelves in Korea, rather than a version reformulated for US retail. That is the whole reason to buy a Korean-market brand from a specialist rather than a general retailer.

Where does Deep Cera Bakuchiol Plumping Serum fit if I already use sunscreen or makeup?

Apply Deep Cera Bakuchiol Plumping Serum before sunscreen or makeup, and let it absorb fully first so it does not pill under the next layer. Sunscreen still goes on last in the morning, and makeup after that, regardless of how many treatment steps come before it.

Who is Deep Cera Bakuchiol Plumping Serum suited for?

It is not restricted to any one skin tone or age group. As with any new step, patch-test on the inner arm first if you are new to this formula or to EQQUALBERRY.

How it works

Deep Cera Bakuchiol Plumping Serum is an ampoule serum from EQQUALBERRY. EQQUALBERRY is a Korean serum-focused skincare brand, each product built around a stated pairing of named actives on its own label. On this jar's own ingredient list, Niacinamide, Bakuchiol, Ceramide NP, Hydroxyethyl Urea, Squalane are named directly, which is what the key-actives panel on this page is built from rather than from the product name alone. Niacinamide is a vitamin B3 derivative that Korean formulas lean on for tone and texture support, and it is why this ampoule serum is positioned the way it is. Use it after toner and before moisturizer, as the routine's concentrated treatment step, giving it a minute to settle before the next layer goes on. EQQUALBERRY sells this as the Korean-market formula, the same one stocked on shelves in Korea rather than a version built for the US market.

1 of 6

73 of 75 explained

Aqua/Water/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.
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.
Cetyl Ethylhexanoate emollient: Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
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.
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.
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.
Pentaerythrityl Tetrabehenate occlusive: A hard wax ester built from a long-chain fatty acid. It raises the melting point of a stick so it holds shape.
Diethoxyethyl Succinate solvent: Diethoxyethyl Succinate is a solvent that helps water-resistant actives spread and sink in evenly. It also leaves a light, silky feel.
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.
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.
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.

Melia Azadirachta Flower 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.
Hydroxyethyl Urea humectant: Hydroxyethyl Urea is a humectant that holds a lot of water for its size and stays comfortable at high levels. It is used where a formula needs to feel deeply hydrating without oil.
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.
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.
Coccinia Indica Fruit Extract plant extract: Coccinia Indica is ivy gourd. Its fruit extract is used as a conditioning, hydrating plant extract in Korean formulas.
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.
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.
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.
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.
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.
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.
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.
2,3-Butanediol humectant: 2,3-Butanediol is a fermentation-derived glycol. It hydrates and, like the other longer glycols, makes a formula harder for microbes to grow in.
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.
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.
Glyceryl Stearate emulsifier: Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
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.
Citrus Aurantium Bergamia (Bergamot) Fruit Oil fragrance component: Bergamot Fruit Oil is a citrus essential oil and the top note of eau de cologne. It scents a formula; citrus oils are the aromatic class most likely to bother reactive 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.
Rubus Fruticosus (Blackberry) Fruit Extract plant extract: Blackberry fruit extract. Like the other dark berries it is rich in anthocyanins and is used as a plant antioxidant.
Vaccinium Macrocarpon (Cranberry) Fruit Extract plant extract: Cranberry fruit extract, acidic and high in proanthocyanidins. It is used as an antioxidant berry extract.
Vaccinium Angustifolium (Blueberry) Fruit Extract plant extract: Lowbush blueberry fruit extract, high in anthocyanins. Berry extracts are used as plant antioxidants and can tint a formula.
Rubus Idaeus (Raspberry) Fruit Extract plant extract: Raspberry fruit extract, carrying fruit acids, sugars and anthocyanins. It is used as an antioxidant-rich conditioning extract.
Sambucus Nigra Fruit Extract plant extract: Elderberry fruit extract, rich in anthocyanins. It is used as a plant antioxidant.
Sodium Lactate humectant: Sodium Lactate is the salt of lactic acid and one of the components of skin's own natural moisturising factor. At the levels used here it is a humectant and buffer rather than an exfoliant.
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.
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.
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.
Salvia Officinalis (Sage) Oil fragrance component: Sage essential oil. It scents a formula and carries the plant's own aromatic compounds, which is also why it can bother reactive skin.
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.
Octyldodecanol emollient: Octyldodecanol is a branched fatty alcohol used as an emollient and as a solvent for pigments and mineral powders. It thickens slightly and leaves a soft finish.
Polyglyceryl-4 Caprate emulsifier: Polyglyceryl-4 Caprate is a mild sugar-derived solubiliser used to dissolve fragrance and oil into watery formulas.
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.
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.
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.
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.
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.
Astaxanthin antioxidant: Astaxanthin is a deep red antioxidant from microalgae, the pigment that makes salmon pink. It is oil soluble, colours a formula noticeably, and is used as an antioxidant.
Pentylene Glycol humectant: Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
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.
Palmitoyl Tripeptide-1 peptide: Palmitoyl Tripeptide-1 is a short peptide with a fatty tail added so it can travel through the oily outer layer of skin. It is used for the look of firmness and is almost always paired with palmitoyl tetrapeptide-7.
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.
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.
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.
Palmitoyl Tetrapeptide-7 peptide: Palmitoyl Tetrapeptide-7 is a four-amino-acid peptide with a fatty tail, used for the look of fine lines. With palmitoyl tripeptide-1 it forms the pairing sold as Matrixyl 3000.
Oligopeptide-32 peptide: A short amino acid chain used as a conditioning peptide, usually one of several oligopeptides declared together.
Oligopeptide-29 peptide: A short chain of amino acids used as a conditioning peptide. Oligopeptide numbers are registry entries, not strengths.
Acetyl Hexapeptide-8 peptide: Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
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.
Acetyl Tetrapeptide-2 peptide: Acetyl Tetrapeptide-2 is a four-amino-acid peptide used for the look of firmness, particularly in eye and neck formulas.
Acetyl Tetrapeptide-3 peptide: Acetyl Tetrapeptide-3 is a four-amino-acid peptide used for the look of density and firmness. It appears in scalp formulas as often as in facial ones.
Acetyl Octapeptide-3 peptide: Acetyl Octapeptide-3 is an eight-amino-acid peptide used for the look of expression lines. It is usually paired with acetyl hexapeptide-8 rather than used alone.
Palmitoyl Pentapeptide-4 peptide: Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
Oligopeptide-6 peptide: Oligopeptide-6 is a short synthetic peptide used in multi-peptide serums. Its number is a catalogue index, so it carries no ranking against oligopeptide-1 or oligopeptide-2.
Hexapeptide-9 peptide: Hexapeptide-9 is a six-amino-acid peptide used for the look of firmness and elasticity. It is water soluble and appears in peptide blends rather than alone.
Nonapeptide-1 peptide: Nonapeptide-1 is a nine-amino-acid peptide used for the look of uneven tone rather than for firmness, which makes it unusual among cosmetic peptides.
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.
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.

How to use

Use the Deep Cera Bakuchiol Plumping Serum after toner and before moisturizer, morning and evening.
Apply a proper amount onto skin and tap to aid absorption.
Toner first so the surface is damp, then this, then about a minute before your moisturizer goes over the top.
Twice a day, every day. Do not stack it with a second serum of the same kind; two hydrating serums in one routine do the work of one.

Worth knowing

New to this formula or to the brand: patch-test on the inner arm and wait a day before applying it to the face.
Discontinue use and rinse the area with water if redness, itching or irritation develops.
