How it works
The panel on this serum names ten forms of hyaluronic acid rather than one: Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Hydroxypropyltrimonium Hyaluronate, Dimethylsilanol Hyaluronate, Hydrolyzed Sodium Hyaluronate, Potassium 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 Sea Water, Niacinamide and Melia Azadirachta Leaf Extract. Sea Water is filtered and desalinated seawater used in place of plain water. It carries magnesium, calcium and potassium, so it brings the mineral balance of the base closer to skin's own.
Key benefits
- Ten forms of hyaluronic acid on one panel, not a single token inclusion
- Sea Water on the same panel, the formula's mineral
- Niacinamide on the same panel, the formula's active
- 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 Hydrating 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 Hydrating 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 standardseoul.co.kr on 30 August 2026.
40 of 43 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.
- Sea Water mineral
- Sea Water is filtered and desalinated seawater used in place of plain water. It carries magnesium, calcium and potassium, so it brings the mineral balance of the base closer to skin's own.
- 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.
- 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.
- 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.
- 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.
- Aloe Barbadensis Flower Extract plant extract
- Aloe Flower Extract comes from the flower rather than the leaf gel. It is used as a conditioning plant extract.
- Solanum Melongena (Eggplant) Fruit Extract plant extract
- Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.
- Simmondsia Chinensis (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.
- Corallina Officinalis Extract plant extract
- Corallina Officinalis is coral seaweed, which holds calcium and magnesium in its structure. Its extract is used as a mineral-rich conditioning ingredient.
28 more explained
- Curcuma Longa (Turmeric) Root Extract plant extract
- Turmeric Root Extract carries curcuminoids, well studied plant antioxidants. It is used for the look of dullness and uneven tone, and it tints a formula faintly yellow.
- Ocimum Sanctum Leaf Extract plant extract
- Ocimum Sanctum is holy basil, or tulsi. Its leaf extract carries plant antioxidants and is used in formulas built for the look of stressed, 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.
- 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.
- Sodium PCA humectant
- Sodium PCA is one of the substances skin makes for itself to hold water, part of what dermatology calls the natural moisturising factor. Added to a formula it is a strong humectant that suits skin that dehydrates quickly.
- 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.
- 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.
- 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.
- Ectoin humectant
- Ectoin is a small molecule that microbes in salt flats and hot springs make to survive extreme conditions. In skincare it holds water tightly around itself, which is why it appears in formulas aimed at reactive, easily dehydrated skin.
- 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.
- 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.
- Dipotassium Phosphate pH adjuster
- Dipotassium Phosphate is a buffer salt. Paired with its more acidic partner it holds a formula at a steady pH.
- Acetyl Glutamine amino acid
- Glutamine with an acetyl group added, which makes it more stable in water. It is used as a conditioning amino acid.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Cellulose Gum thickener
- Cellulose Gum is plant cellulose modified to dissolve in water. It thickens, holds particles in suspension and gives a smooth, slippery body.
- 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.
- 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.
- Sodium Stearoyl Glutamate emulsifier
- Sodium Stearoyl Glutamate is an amino-acid-derived emulsifier. It holds oil and water together and is mild enough for formulas built for reactive skin.

How to use
- Use the Hydrating 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.
