How it works
The Micro Dual Serum Toner is a 150ml toner, used straight after cleansing, morning and evening, while the face is still damp. The active it is built around is Niacinamide, named sixth on its own ingredient list. The same list carries Allantoin, Adenosine and Streptococcus Thermophilus Ferment, 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 toner format rather than by the list alone. This is the Original Korean Formula, the toner Biodance 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 toner's own ingredient list it is named sixth.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it thirteenth on this toner'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. It is named fifteenth on this toner's list, alongside Niacinamide.
Streptococcus Thermophilus Fermentferment
Streptococcus Thermophilus Ferment is a yoghurt-culture ferment. It is used for its conditioning effect on the outer layer of skin. It is named eleventh on this toner's list, alongside Niacinamide.
Beta-Glucanpolysaccharide
Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin. It is named eighteenth on this toner's list, alongside Niacinamide.
Biodance Micro Dual Serum Toner
Where does this toner go in my routine?
Straight after cleansing, morning and evening, while the face is still damp. Anything thinner than a toner 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 toner or a US version?
The Korean-market one, Niacinamide and all. We match this toner 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?
Allantoin, Adenosine and Streptococcus Thermophilus Ferment. The order they are printed in on this toner's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Beta-Glucan, Vitis Vinifera (Grape) Seed Oil and Hippophae Rhamnoides Oil.

How to use
- Use the Micro Dual Serum Toner straight after cleansing, morning and evening, while the face is still damp.
- A coin-sized pool into the palms, pressed over the face in two passes rather than swept on with a cotton pad.
- Your serum goes on next, then your moisturizer. This layer is what the serum above it holds on to.
- Twice a day, every day. Do not follow it with a separate light essence as well; the point of an essence toner is that one layer covers both.
Worth knowing
- Skin that is actively broken out or irritated does best starting this once daily before moving to twice.
- Anyone using a prescription retinoid or a strong acid exfoliant elsewhere in their routine should introduce this alongside it gradually.

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.
