How it works
The Refreshing Sea Kelp Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The plant extract it is built around is Laminaria Japonica Extract, named twenty-sixth on its own ingredient list. The same list carries Niacinamide, Adenosine and Tocopherol, so the plant extract is not the only thing on it worth naming. How much of the Laminaria Japonica Extract 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 Biodance sells in Korea, Laminaria Japonica Extract and all.

Key actives
Laminaria Japonica Extractplant extract
Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient. The name on the box points at it, and it is named twenty-sixth on this serum's own ingredient list.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named fourth on this serum's list, alongside Laminaria Japonica Extract.
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 fourteenth on this serum's list, alongside Laminaria Japonica Extract.
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. It is named twenty-second on this serum's list, alongside Laminaria Japonica Extract.
Melia Azadirachta Leaf Extractplant extract
Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin. It is named fifteenth on this serum's list, alongside Laminaria Japonica Extract.
Biodance Refreshing Sea Kelp Serum
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 Laminaria Japonica Extract and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Laminaria Japonica Extract 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 Laminaria Japonica Extract?
Niacinamide, Adenosine and Tocopherol. The order they are printed in on this serum's panel is the order on the box, so you can see where Laminaria Japonica Extract sits relative to them. Further down the same panel: Melia Azadirachta Leaf Extract, Jania Rubens Extract and Kjellmaniella Gyrata Extract.

How to use
- Use the Refreshing Sea Kelp Serum after your toner and before your moisturizer, morning and evening.
- Two or three drops for the whole face, pressed in with the flats of your fingers while skin is still damp.
- Follow with a moisturizer within a minute or two, because a thin serum left bare dries down and takes surface water with it.
- Twice a day, every day. Do not use it as your only layer on skin that already feels tight; a serum is not a seal.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Laminaria Japonica Extract on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Laminaria Japonica Extract rather than to three changes at once.
