How it works
The Squalane S4 Moisture Ampoule is an ampoule in VT Cosmetics' line, and the entries doing the work on its list are Niacinamide, Panthenol and Adenosine. Niacinamide is a tone-and-barrier workhorse, one of the most studied actives in Korean formulation. Panthenol sits alongside it: pro-vitamin B5, carried for softness and moisture. Adenosine is a wrinkle-care ingredient recognized by Korea's own cosmetic authority. Dipotassium Glycyrrhizate is a licorice-derived calming agent. Squalane is also on the list: a lightweight, non-comedogenic emollient.

VT Cosmetics Squalane S4 Moisture Ampoule
Is the Squalane S4 Moisture Ampoule on this page the Korean-market formula?
Yes. It is the release VT Cosmetics makes for sale inside Korea. The same product name can carry a different ingredient list or a different size in an export version, and we list only the Korean one. The Reedle Shot family is a Korean shelf phenomenon, sold in strengths a US listing usually stocks one rung of at a time.
Where does the Squalane S4 Moisture Ampoule sit in a routine?
It occupies the concentrated serum and ampoule step. Build the routine around the step you are replacing rather than the brand you recognise: a cleanser, a hydrating toner, one serum and one moisturizer is a complete routine, and four products chosen carefully tell you more about your skin than ten bought at once.
What size is the Squalane S4 Moisture Ampoule?
30 ml. That is the size VT Cosmetics sells in Korea for this product; we do not substitute an export format or a US size for the Korean one.
How do I check that this VT Cosmetics unit is genuine?
VT Cosmetics publishes no verification route of its own, so ignore any third party site that claims to run one for it. Match the batch code on the box against the code printed on the bottle or tube itself; the two are stamped separately and should agree. Your unit ships with its Korean-market barcode and its batch code intact, because the production date stays yours to read.
How does buying the Squalane S4 Moisture Ampoule here compare with a US retailer?
This is the unit built for the Korean market, with the Korean barcode and batch code intact on the box. A US listing carrying the same product name may be the export version and rarely tells you which one it is sending.

How to use
- Use the Squalane S4 Moisture Ampoule after toner and before moisturizer, morning and evening.
- Half a dropper, or two or three drops, is the amount for a whole face. Press it in rather than spreading it thin.
- It sits between the toner and the moisturizer, and it is the layer most worth leaving alone for a minute before anything covers it.
- Twice a day, every day. Do not use it as a spot application on one area; an ampoule is a routine step, not a targeted dose.
Worth knowing
- Anyone new to an ingredient on this formula's own list still does well to patch test on the inner arm before a first full application.

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.
