How it works
Niacinamide leads the ingredient panel on this ampoule. 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. On this panel it sits alongside Adenosine, Dipotassium Glycyrrhizate and Camellia Sinensis Leaf Extract. 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.

Key actives
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.
Adenosine
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.
Dipotassium Glycyrrhizate
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
Camellia Sinensis Leaf Extract
Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
When do I use S4 Moisture Ampoule in my routine?
Use S4 Moisture Ampoule 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 30 ml bottle typically lasts about six to eight weeks, though usage varies with how much product a person applies each time.

Payment and security
We accept
How to use
- Cleanse and tone first so the skin is clean and slightly damp, not dripping wet.
- Dispense a few drops of S4 Moisture Ampoule 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.
