## In short

I tested HEEDA Glutathione Glow Radiance Serum for two weeks on combination, sensitive skin dealing with winter dryness and dullness. Its watery texture layered lightly under makeup, and I felt my skin looked clearer and more luminous, though the results were personal observations.

## How did it feel on combination, sensitive skin?

I started using it when winter dryness and a dull complexion were concerns. My T-zone gets oily while my U-zone is dry, and because I tend to have lingering blemish marks, I chose it hoping for a clear, luminous glow.

## Was the watery texture suitable before makeup?

It was less heavy than I expected and watery enough to run on the back of my hand. It felt like it adhered lightly when applied, and even several layers did not feel burdensome. Even after applying moisturizer and sunscreen, it did not seem to sit on top of the skin or make my makeup pill.

## What changes did I notice after two weeks?

I thought brightening changes would take longer to notice, but by the second week, I felt my skin tone looked clearer than before. Overall dullness seemed reduced and my tone looked a little more even, while a luminous glow seemed to remain in the morning even with just the serum.

However, these changes are personal observations from my own conditions of use and skin state.

## How did I use it in my evening routine?

In the evening, I used two layers. I liked that my skin felt moisturized within while the surface looked relatively smooth, and the next morning, my skin’s shadows seemed less pronounced.

## Who might it suit?

It may be worth considering if you are looking for a lightweight, moisturizing glow serum or one to layer with multiple skincare steps. I did not experience stinging on my sensitive skin, but skin reactions can vary from person to person.
