How it works
The Biome Double Defense Sunscreen is a 50ml sunscreen, used as the last step of the morning routine, over moisturizer and under makeup. The active it is built around is Niacinamide, named eighth on its own ingredient list. The same list carries Adenosine, Lactobacillus Ferment and Saccharomyces Ferment Filtrate, 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 sunscreen format rather than by the list alone. This is the Original Korean Formula, the sunscreen AXIS-Y sells in Korea, Niacinamide and all.
Key benefits
- Niacinamide, the active this sunscreen is built around
- Adenosine on the same list, an active
- Lactobacillus Ferment, Saccharomyces Ferment Filtrate and Galactomyces Ferment Filtrate on the same list, ferments
- Bifida Ferment Lysate and Tocopherol further down the same list
- Vaccinium Macrocarpon (Cranberry) Fruit Extract and Copaifera Officinalis (Balsam Copaiba) Resin further down the same list
- Niacinamide named eighth on the manufacturer list printed on this page
Where does this sunscreen go in my routine?
As the last step of the morning routine, over moisturizer and under makeup. Anything thinner than a sunscreen 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 sunscreen or a US version?
The Korean-market one, Niacinamide and all. We match this sunscreen 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?
Adenosine, Lactobacillus Ferment and Saccharomyces Ferment Filtrate. The order they are printed in on this sunscreen's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Galactomyces Ferment Filtrate, Bifida Ferment Lysate and Tocopherol.

How to use
- Use the Biome Double Defense Sunscreen as the last step of the morning routine, over moisturizer and under makeup.
- At the last step of skin care routine, evenly spread moderate amount over face and neck. Re-apply every 2 to 3 hours if needed.
- Nothing skincare goes over it. It is the last thing on in the morning, and it is never mixed into the moisturizer underneath it.
- Every morning, and again through the day as the instruction on the pack directs. Do not stir it into your moisturizer to save a step.
Worth knowing
- Patch test on the inner arm before a first full-face application if skin tends to react easily.
- Store away from direct sunlight and high heat to keep the texture and scent stable over time.
- Introduce one new active at a time when adding this into an existing routine.
