Beauty of Joseon Glow Deep Serum Rice + Alpha-Arbutin

It helps skin look brighter and more even over time. Alpha-arbutin and niacinamide, both high in the formula, target the look of dark spots, post-acne marks and dullness, while rice bran water, panthenol and trehalose keep skin hydrated. Results build gradually, so give it four to eight weeks of daily use with sunscreen.

The box doesn't state percentages, but alpha-arbutin and niacinamide are the seventh and eighth ingredients, so they're present in meaningful amounts. It's a gentle, everyday brightening serum rather than an intensive treatment, which makes it a good first brightening product and suitable for sensitive skin.

After cleansing and toner, apply a few drops to your face and pat gently until absorbed, as the box recommends. Follow with moisturiser. You can use it morning and evening; during the day, always finish with sunscreen, as daily UV protection is essential for fading dark spots.
