## Why did I try it on dehydrated oily skin?

I usually have slight dark spots and redness, and during seasonal transitions my complexion tends to feel red and dull. Having tried the brand’s cleansing balm, I decided to try its serum as well.

## What are the texture and application like?

The serum came in a glass bottle with a dropper. On the back of my hand, it felt more viscous than toner but lighter than an ampoule, and I found it relatively non-sticky.

## How did it feel after two weeks of morning-and-night use?

I compared week one and week two after applying only a light layer of serum right after cleansing. I felt that the red irritation beside my nose and the dark spots on my cheeks seemed less noticeable than before. These are my personal experience and observations.

When I used it in the morning, I was pleased that my makeup seemed to apply brighter and smoother. Since I had only used it for two weeks, I wanted to keep using it and watch for longer-term changes.
