In short

Is the watery texture non-sticky?

When I opened the cap, the formula flowed like water. It felt as though it settled transparently onto my skin, and I did not notice much of the usual serum-like viscosity or heaviness. It also had a slight cooling feel, so it did not feel burdensome to use in the morning.

How did I use it for two weeks?

During the seasonal transition, my skin looked dull and seemed to be losing firmness, so I used it as a serum for an inner-glow look for about two weeks. Since my skin tends to be oily, I applied a thin layer in the morning and a slightly more generous amount at night, but it still did not feel sticky or heavy.

How did my skin look after two weeks?

I prefer a subtle glow that seems to come from within rather than an oily-looking shine, and this product felt closer to that. After about two weeks, my skin looked less dull in the mirror and its texture felt a little smoother.

My base makeup also seemed to adhere better than before, and I felt that areas that used to become patchy in the afternoon did so less. However, changes in my skin tone or darker areas are observations from my personal use environment.

According to the original product information, high-purity glutathione and niacinamide are presented as the key ingredients. More than the ingredients themselves, the light water-glow texture and low-tack feel stood out most to me.
