How it works
The panel on this serum names ten forms of hyaluronic acid rather than one: Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Dimethylsilanol Hyaluronate, Hydrolyzed Sodium Hyaluronate, Potassium Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate Dimethylsilanol, Sodium Acetylated Hyaluronate. 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. On this panel it sits alongside Niacinamide, Eclipta Prostrata Extract and Melia Azadirachta Leaf Extract. 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.
Key benefits

- Niacinamide on the same panel, the formula's active
- Eclipta Prostrata Extract on the same panel, the formula's plant extract
- 30 ml to a unit
- Korean GS1 barcode matched against a Korea sourcing supplier's record for this item
Inside the formula
Inside the formula
What is the Standard Seoul Firming Bouncy Boost Serum for?
It is a Standard Seoul serum sized at 30 ml, used after toner, before moisturizer. In practice that means it goes on a few drops smoothed over the face and pressed in until absorbed. It is one step in a routine rather than a stand-alone treatment.
Where does a serum go in my routine?
After toner and before moisturizer. That is the standard serum-step placement, whether it is used once a day or in both the morning and evening routine. Applying it to slightly damp skin after toner helps it spread evenly.
Can I use it with another serum?
One serum step at a time is the more common approach so that neither one is diluted against the other. If more than one serum is wanted, alternating them by day or by time of day is a simpler way to fit both in without stacking actives.
Is this the Korean-market version of the Firming Bouncy Boost Serum?
Yes. What ships is the Standard Seoul formula sold on shelves in Korea, in the same 30 ml, not a version reformulated for the US market.
Is this safe for sensitive skin?
There is no single answer that fits every skin, so a patch test on a small area is the safer way to try any new serum for the first time. Watching for redness or irritation over a day or two before using it on the full face or body is the usual approach.

Ingredient list read from incidecoder.com on 30 August 2026.
46 of 50 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.
- Diphenyl Dimethicone silicone
- Diphenyl Dimethicone is a glossy silicone used to add shine and a smooth film, particularly in lip and highlighting textures.
- 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.
- 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.
- 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.
- Eclipta Prostrata Extract plant extract
- Eclipta Prostrata is false daisy, long used in Ayurvedic and East Asian practice. Its extract is used as a conditioning plant extract, most often in scalp and hair formulas.
- Melia Azadirachta Leaf 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.
- Moringa Oleifera Seed Oil emollient
- Moringa Seed Oil is high in oleic acid and behenic acid and very stable. It is a conditioning emollient with a light, non-sticky finish.
- Aureobasidium Pullulans Ferment ferment
- A ferment of the yeast-like fungus that pullulan is made from. It yields water-holding beta-glucans and is used as a conditioning ferment.
- 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 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.
- Macadamia Ternifolia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
34 more explained
- 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.
- Chitosan film former
- Chitosan comes from the shells of crustaceans. It carries a positive charge, so it clings to skin and hair as a thin film, and it is a shellfish-derived ingredient.
- 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.
- Sodium Chloride thickener
- Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
- 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.
- 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.
- PVP film former
- PVP is polyvinylpyrrolidone, a water-soluble polymer that dries into a clear flexible film. It holds pigment or hair in place and washes off with water.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- 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.
- 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.
- 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.
- 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.
- Brassica Campestris (Rapeseed) Sterols emollient
- Phytosterols are plant sterols, structurally close to the cholesterol in skin's own lipid layer. They soften skin and help the oil phase of a formula hold together.
- 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.
- 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.
- 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.
- Phytosteryl/Behenyl/Octyldodecyl Lauroyl Glutamate barrier lipid
- An amino-acid-based lipid built on plant sterols. It structures the oil phase of a cream and echoes the lipid mix that already sits between skin cells.
- Aluminum/Magnesium Hydroxide Stearate dispersant
- A mineral soap used to suspend powders and thicken an oil phase, which is what stops pigment settling to the bottom of a bottle.
- Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate antioxidant
- This is a stabiliser that keeps the oils and fragrance in a formula from oxidising. Its job is the shelf life of the product rather than any effect on skin.
- Potassium Cetyl Phosphate emulsifier
- Potassium Cetyl Phosphate is an emulsifier prized for keeping powdered ingredients evenly suspended, which is why tinted and mineral-powder textures use it.
- 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.
- 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.
- 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.
- 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.
- Tris(Tetramethylhydroxypiperidinal) Citrate antioxidant
- A hindered-amine antioxidant used to keep a formula from breaking down in light and air. It works on the product rather than on skin.
- 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.
- Fullerenes antioxidant
- Fullerenes are hollow cage-shaped carbon molecules, C60 the best known of them. They are used as an antioxidant and are notably more stable than the vitamin antioxidants.

How to use
- Use the Firming Bouncy Boost Serum after toner and before moisturizer, morning and evening.
- For first use, remove cap and screw on the dropper. Shake the two formulas well before use. Take an appropriate amount of the product and apply it evenly to the skin.
- 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
- Layering more than one serum in the same step can dilute what each one is doing rather than add benefit, so one serum at a time is usually enough.
- As with any new skincare step, patch-test on a small area first if you have a history of reacting to new products.
