How it works
Round Lab Camellia Deep Collagen Firming Ampoule is built as a serum, so its texture and finish are designed around one specific place in a routine rather than several. The formula's own ingredient list carries Niacinamide, Adenosine, Panthenol (Pro-Vitamin B5) among its named ingredients, placed at a level consistent with a serum rather than a spot treatment. The texture is built for use after your toner or essence and before your moisturizer, the concentrated middle step of a routine, which is why it behaves differently on skin than a product meant for a different point in a routine. This is the Korean-market formula of the camellia deep collagen firming ampoule, the version sold on shelves in Korea rather than a formula reworked for a different market.
Key benefits
- Camellia Deep Collagen Firming Ampoule is Round Lab's serum, sourced for the Korean market rather than reformulated for US shelves.
- Carries Betaine, which is a sugar beet-derived humectant that helps this formula feel less stripping on contact.
- Carries Niacinamide, which is the brightening, barrier-supporting workhorse behind most Korean tone-evening formulas, and it layers easily under sunscreen and makeup.
- Carries Camellia Japonica Flower Extract, which is camellia extract, prized in Korean skincare for its skin-conditioning fatty acid content.
- Ships with the Korean-market barcode and batch code intact, the same box sold on Korean shelves rather than a US repack.
- Suited to shoppers targeting uneven tone and dark spots.
Inside the formula
Inside the formula
Is this the same formula sold in Korea, or a version made for the US market?
This is the Korean-market formula, the same one sold on shelves in Korea, not a separate version reformulated for US retail. The pack you open matches what a shopper in Seoul buys.
Where does this step go in a routine?
It belongs after your toner or essence and before your moisturizer, the concentrated middle step of a routine. Placing it earlier or later than that changes how it feels going on and how well the steps after it absorb, so keeping it in that order is worth doing even on a simplified routine.
Can I use this if my skin runs sensitive?
This serum is formulated with skin types like normal skin, dry skin in mind, but any new product is worth a patch test first if your skin reacts easily. A short patch test on the inside of your arm or behind an ear is worth doing with any new product before it goes on your face, and that goes for sensitive skin most of all.
How long before I will know if this is right for my skin?
Give it a full week or two of consistent use before judging, since a single use rarely tells you much either way. Watch for how skin feels rather than for any specific number, and stop use if you notice ongoing irritation.

40 of 43 explained
- Purified 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Dipentaerythrityl Hexa C5-9 Acid Esters emollient
- A heavy branched ester used to give lip and stick formulas gloss and cling without stickiness.
- Camellia Japonica Flower Extract (10,100 Ppm) plant extract
- Camellia Japonica Flower Extract comes from the flower of the Korean camellia. It is used as a conditioning, hydrating extract.
- Jojoba Seed Oil emollient
- Jojoba Oil is a liquid wax rather than a true oil, and its structure is close to human sebum, which is why it absorbs so readily. It is an emollient that leaves a soft, non-greasy finish.
- 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.
28 more explained
- Irish Moss Extract plant extract
- Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
- 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.
- 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.
- Chlorella Vulgaris Extract plant extract
- Chlorella Vulgaris is a freshwater green algae. Its extract carries proteins, chlorophyll and amino acids and is used as a conditioning ingredient.
- Glucose humectant
- Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
- 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.
- 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.
- Hydrolyzed Collagen (1,010 Ppm) protein
- Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
- Fructooligosaccharides humectant
- Fructooligosaccharides are short fructose chains used as humectants and as food for the skin's own resident microbes.
- Fructose humectant
- Fructose is a simple sugar used as a light humectant. It holds water in the outer layer and often arrives as part of a fruit or honey extract.
- Inositol humectant
- Inositol is a sugar-like compound found in the body. In skincare it is a humectant that also helps a formula feel conditioning rather than merely wet.
- 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.
- 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.
- 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.
- 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.
- Cyanocobalamin vitamin
- Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin.
- Quercetin antioxidant
- Quercetin is one of the most widespread plant flavonoids, found in onion skin, apple peel and tea. It is a plant antioxidant and is yellow, so it tints a formula.
- Soluble Collagen (1 Ppm) 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.
- 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.
- 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.
- Polyacrylate Crosspolymer-6 thickener
- Polyacrylate Crosspolymer-6 is a thickener chosen for a notably fresh, bouncy gel feel that breaks down to water on the 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.
- Sodium Dilauramidoglutamide Lysine barrier lipid
- An amino-acid-based lipid built from glutamic acid and lysine. It behaves like the lipids between skin cells and forms a liquid-crystal structure that holds water in.
- 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.
- 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.
- 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.
- Dimethyl Isosorbide solvent
- Dimethyl Isosorbide is a solvent used to dissolve actives that water and oil both reject, and to carry them evenly through the outer layer of skin. It appears in vitamin C and retinoid formulas for exactly that reason.
- Dextrin thickener
- Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.

How to use
- Use the Camellia Deep Collagen Firming Ampoule after toner and before moisturizer, morning and evening.
- Apply an appropriate amount on clean skin and gently pat to aid absorption.
- It sits between the toner and the moisturizer, and it is the layer most worth leaving alone for a minute before anything covers it.
- Twice a day, every day. Do not use it as a spot application on one area; an ampoule is a routine step, not a targeted dose.
Worth knowing
- Introduce a new serum gradually rather than every day at first, so it is easier to tell if skin is reacting to it specifically.
- Seal it with a moisturizer rather than leaving it to sit alone, since a serum is a middle step and not built to finish a routine.
