Glutathione serum for dehydrated combination skin: HEEDA Glow Serum
In short
I used HEEDA Glutathione High-End Glow Radiance Serum morning and night for about two weeks on dehydrated combination, somewhat sensitive skin in Korea. Its lightweight texture absorbed quickly, and I felt my complexion and makeup base looked a little more even, though skin responses can vary.

How did it feel on dehydrated combination skin?

In winter, I have dehydrated combination skin that easily feels dry beneath the surface and can look uneven in tone. I tend to worry about breakouts or stinging when trying a new serum, but this felt comfortable from the first use, so I used it every day.

What were the texture and absorption like?
It had a thin, refreshing water-glow texture that absorbed quickly when spread over the skin. There was very little stickiness or product sitting on the surface, and even when I applied another layer on dry days, it did not feel heavy or suffocating.

After absorption, it felt like it left a subtle glow rather than an oily shine.

How did my complexion look after about two weeks?

After a day or two of use, my skin condition seemed to change, and after about two weeks, I felt my skin tone looked a little more even. It also seemed less dull.

Especially when I used it before morning makeup, I felt my base went on more evenly than before. I also felt my makeup stayed relatively neat as time passed.

How did I use it?
I used the serum after toner following cleansing. In the morning, I applied it before makeup, and at night, I used it as part of my skincare routine. On dry days, I layered it.

What should you keep in mind?

The product is described as containing both glutathione and niacinamide. I felt the surface of my skin looked smoother, so I also used it on days when I wanted to simplify my skincare steps. Skin reactions and how it feels can vary from person to person.
