How it works
Collagen Water leads the ingredient panel on this serum. Collagen Water is a collagen solution used in place of plain water as a formula base. It hydrates and leaves a conditioned feel; the collagen molecule itself stays on the surface. On this panel it sits alongside Niacinamide and Adenosine. 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.

Inside the formula
Inside the formula
When do I use Reto Collagen Pink Micro Bubble Serum in my routine?
Use Reto Collagen Pink Micro Bubble Serum after cleansing and toner, before your moisturizer or cream. It is a leave-on step, so apply it to a clean face and let it settle for a minute before layering the next product. Most people use it once in the morning and once at night, though a single evening application is fine while your skin adjusts to a new step.
Can I layer it with other serums or ampoules?
Yes. Apply thinner, more watery formulas first and heavier creams last, so this ampoule generally goes after a toner and before a thicker serum or moisturizer. If you use it alongside an actives-heavy routine, introduce it on its own for the first week so you can tell what any reaction is coming from.
Does it feel greasy or heavy on the skin?
No. It has a water-forward, leave-on base rather than a heavy oil or wax base, so it absorbs into the surface rather than sitting on top of it. Most people describe the feel as light and quickly absorbed, not tacky or greasy.
Is this the same formula sold in Korea?
Yes. This is the Korean-market VT Cosmetics release, imported with its original Korean-language packaging, barcode, and batch code intact, rather than a version reformulated or repackaged for US retail. We check that batch code against the one on the box before it ships, instead of relying on the listing alone.
How long does one bottle last with daily use?
At roughly a few drops per application, twice a day, a 70 ml bottle typically lasts about six to eight weeks, though usage varies with how much product a person applies each time.

27 of 27 explained
- Collagen Water protein
- Collagen Water is a collagen solution used in place of plain water as a formula base. It hydrates and leaves a conditioned feel; the collagen molecule itself stays on the surface.
- 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.
- 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.
- Sorbitol humectant
- Sorbitol is a sugar alcohol used as a humectant. It hydrates like glycerin with a smoother, less sticky finish, and it adds a little body to watery textures.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- Methyl Gluceth-20 humectant
- Methyl Gluceth-20 is a sugar-derived humectant. It holds water in the outer layer of skin and gives a smooth, cushioned slip that plain glycerin does not.
- 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.
- 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.
- C12-14 Alketh-12 emulsifier
- C12-14 Alketh-12 is a solubiliser used to keep oils and fragrance dissolved in a water-based formula.
- 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.
- Lecithin emulsifier
- Lecithin is a soy or sunflower-derived phospholipid, the same class of molecule cell membranes are built from. It emulsifies oil into water and is the basis of the liposomes formulators use to carry actives.
- 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.
15 more explained
- Hydrolyzed Collagen 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.
- Polyglyceryl-10 Myristate emulsifier
- Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Beta Vulgaris (Beet) Root Extract plant extract
- Beetroot extract. It carries betaine, sugars and the red betalain pigments, so it works as a humectant rich botanical and can tint a formula.
- 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.
- 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.
- 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.
- 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.
- 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.

- Dispense a few drops of Reto Collagen Pink Micro Bubble Serum into the palm or fingertips and press it over the face and neck.
- Pat gently until it is absorbed rather than rubbing it in.
- Follow with a moisturizer or cream within a minute or two to seal the hydration in.
Worth knowing
- Patch test on the inner arm before the first full-face application, as with any new ampoule.
- Stop use and rinse if stinging, redness, or itching develops after application.
