What skin types can use it?

Suitable for all skin types. In particular, it is designed for concerns about dull skin tone and pigmentation. Since your skin may react sensitively to alpha arbutin if you have sensitive skin, it is recommended to perform a patch test before use.

Please recommend the best match?

For skin pigmentation, try layering with Revive Serum and Ginseng Essence Water that contain saponin-rich ginseng water.

Can I use it both day and night?

Yes, you can. However, alpha arbutin is vulnerable to light and heat, so it is recommended for use in the evening.

Do I need to keep it refrigerated?

Avoid direct sunlight and store it in a cool, dark place.

Alpha-arbutin is vulnerable to light and heat, so please use it as soon as possible after opening.
