How did it apply on combination skin with inner dryness?


I used it when my skin looked dull, dark spots were noticeable, and inner dryness flared up as the seasons changed. At first, it spread lightly and fluidly, and felt as though it absorbed quickly into my skin.

With little stickiness, it did not feel burdensome to apply morning and night. Even on days when I did not use multiple skincare steps, my skin seemed to feel less tight underneath. It also did not feel especially heavy or pill even when layered several times.


How did my skin look after two weeks of use?

I did not notice a distinct change at first, but after about two weeks, I felt that my skin tone looked more even in the mirror and previously dull areas looked more refined. Dark spots also seemed lighter, though this is the writer’s personal observation from use.


Rather than leaving only a greasy surface shine, it left a subtle glow. My skin texture looked more refined, and my base makeup also seemed to apply a little more cleanly.


Could I use it on sensitive days and before makeup?

I was concerned that the glutathione and niacinamide combination might be irritating, but I was able to use it comfortably even on days when my skin felt sensitive. It seemed to support makeup without pilling, so it was easy to add to my daily routine.


It may suit those who prefer a light, fresh texture and want continued use to leave their skin tone and texture looking more refined.
