How it works
The RTX INTO SERUM Hyalshot is a 50ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named sixth on its own ingredient list. The same list carries Hydrolyzed Sponge, Adenosine and Mandelic Acid, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum Dr.G sells in Korea, Niacinamide and all.

Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this serum's own ingredient list it is named sixth.
Hydrolyzed Spongeactive
Hydrolyzed Sponge is processed freshwater sponge, which carries fine silica spicules. In a formula it works as a mild physical exfoliant. The panel names it tenth on this serum's list, beside Niacinamide.
Adenosineactive
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. The panel names it eighteenth on this serum's list, beside Niacinamide.
Mandelic Acidexfoliant
It is the AHA used where a formula has to suit darker or easily reactive skin. It is named twenty-fourth on this serum's list, alongside Niacinamide.
Tocopherolantioxidant
Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer. The panel names it twenty-third on this serum's list, beside Niacinamide.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Niacinamide and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Niacinamide and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Niacinamide?
Hydrolyzed Sponge, Adenosine and Mandelic Acid. The order they are printed in on this serum's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Tocopherol, Beta-Glucan and Malus Domestica Fruit Cell Culture Extract.

How to use
- Use it twice a day after the watery step, on a clean face and before any cream.
- Warm a small amount between the fingertips first, then press it over the cheeks, forehead and chin.
- Give it thirty seconds to settle before the next layer goes on, which is what keeps anything from balling up.
- Avoid applying it to skin that is completely dry after a long gap, since a thin layer spreads much further on damp skin.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- Mandelic Acid on this list makes this serum an exfoliating step, so do not stack it with another one on the same night.

As we age, the glue that holds our skin cells together becomes denser, which slows down the natural cell turnover process.

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.
