Key actives
Sodium 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.
Hydrolyzed Hyaluronic Acid
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
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.
Dimethylsilanol Hyaluronate
Dimethylsilanol Hyaluronate is hyaluronic acid joined to a silicon-based group. It hydrates and leaves a smoother, silkier finish than hyaluronic acid alone.
Hippophae Rhamnoides Water
Hippophae Rhamnoides is sea buckthorn. Its water is used in place of plain water as a base and carries traces of the fruit's vitamins.
Niacinamide
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.
Alpha-Arbutin
Alpha-Arbutin is a plant-derived compound, related to the sugar-bound form found in bearberry, used for the look of dark spots and uneven tone. It is stable in water and works at skin-friendly pH.
How to use
- Use the Brightening 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.
What is the Standard Seoul Brightening 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 Brightening 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.

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 Hippophae Rhamnoides Water, Niacinamide and Alpha-Arbutin. Hippophae Rhamnoides is sea buckthorn. Its water is used in place of plain water as a base and carries traces of the fruit's vitamins.
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.

Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
