## What was the texture like after two weeks of use?

I used it during the seasonal transition, when my skin looked dull and felt dry underneath but became oily on the surface. It felt light enough to run when placed on the back of my hand, and it seemed to adhere closely to my skin after application.

For me, it did not feel overly oily or sticky, and it seemed to absorb quickly. Even when I applied it after toner, there was little pilling.

## Was it easy to use before morning makeup?

Absorption is important to me in a serum I use before morning makeup, and this product was easy to use beforehand because of its watery formula that seemed to sink in right away. My makeup finished without feeling lifted or clumped.

## How did my skin tone and glow feel after two weeks?

From around the second week, I felt that my overall tone looked a little more even and that both cheeks, which had seemed dull, looked clearer. My makeup also seemed to look more translucent, but this was a personal observation based on my own skin condition.

Rather than a greasy oil shine, it felt like a subtle glow coming from within the skin. I had felt that only the surface looked fine because of inner dryness, so I liked that a natural glow remained even after makeup.

## Could I use it when my skin felt sensitive?

During the testing period, I did not experience stinging, redness, or breakouts. I tend to worry about dryness or irritation from products containing brightening and glow ingredients, but this felt relatively comfortable for me. Skin reactions can vary from person to person.

## What skin concerns did it suit?

It suited my experience when I was concerned about dullness, inner dryness, and dark spots at the same time and wanted a lightweight glow serum. It may be worth considering if you especially prefer a formula that does not feel heavy in the morning.
