Kojic Acid vs Alpha Arbutin
How the two ingredients differ, and why they are often used together.
Kojic Acid and Alpha Arbutin are two of the most common ingredients in creams for dark spots and uneven-looking tone. They are not rivals: many formulas use both, because they suit different skin and work well together.
Side by side
| Kojic Acid | Alpha Arbutin | |
|---|---|---|
| Where it comes from | Fermentation (first found in rice fermentation for sake) | A stable form of arbutin, found in plants like bearberry |
| Used for | Dark spots, uneven-looking tone | Dark spots, a brighter-looking complexion |
| Feel on skin | Can tingle for some people at first | Generally gentle |
| Results | Gradual, over weeks | Gradual, over weeks |
| Needs sunscreen | Yes | Yes |
Which one should you choose?
If your skin is sensitive, a gentle Alpha Arbutin product is an easy start. If your skin tolerates actives well, Kojic Acid adds a well-known ingredient to the routine. A cream that combines the two, at levels made for daily use, gives you both without layering several products.
Using them together
- Choose one product that contains both, rather than stacking separate serums.
- Apply to clean, dry skin once a day for the first week, then twice if comfortable.
- Use sunscreen every morning.
- Judge the results after 6 to 8 weeks of regular use, in the same light.
