In short

Its watery texture settled quickly and felt comfortable under makeup; on my sensitive skin, it was generally easy to use, though changes in tone and texture were personal observations.

How did the texture and absorption feel after two weeks?


I used it for about two weeks when I was paying attention to inner glow care after being told that my skin looked dull and tired. The water-glow texture spread lightly in my hands and settled relatively quickly without feeling like it sat on the surface.

Rather than the usual oiliness of a serum, it gave my skin a subtle, water-filled-looking sheen. It was also nearly fragrance-free, so it was easy to add to my existing skincare routine.


Could I use it on sensitive skin and before makeup?

New products can sometimes cause breakouts for me, but this one was generally comfortable to use without major irritation. When I applied sunscreen and cushion foundation after it in the morning, I felt that lifting around my nostrils and the emphasis on dry flakes were less noticeable than before.


Even when layered, it did not pill much, and what I liked most was how light it felt before makeup.


How did I layer the serum?

It comes with a dropper, so I spread a thin layer over my whole face after toner. I applied a little more to my dry cheeks and around my mouth, then finished with cream after the serum at night. On nights when I wanted more moisture, I layered it twice.


How did my skin tone and texture feel after two weeks?

The following morning, my skin felt less rough and its texture seemed smoother. After about two weeks, I did not feel that it had become dramatically brighter; instead, areas that had looked dull seemed more even, giving my overall complexion a slightly more uniform appearance.


Pigmentation marks beside my nose and on my chin also looked less pronounced, but these were personal changes I noticed based on my own skin condition. It may be worth considering if you prefer a light, watery feel over a sticky or heavy serum.
