## In short

HEEDA Glutathione High-End Glow Radiance Serum is a Korean skincare serum I used morning and night for about two weeks. Its lightweight watery-glow texture absorbed without stickiness and sat well under foundation; I felt my skin tone and texture looked a little more even, though results may vary by skin type.

## What are the texture and feel of HEEDA serum like?

I used it consistently for about two weeks. When I put it on the back of my hand, it felt light and fresh, as expected of a watery-glow formula, with almost no heaviness or stickiness afterward.

I used it both morning and night. It fit naturally into my skincare routine, and even when I applied it before makeup, my foundation did not feel like it was pilling.

## How did my skin feel after two weeks?

When I looked in the mirror in the morning, the uneven tone that had bothered me felt slightly brighter. Rather than a shiny surface glow, it was closer to a subtle radiance that seemed to come from within my skin.

My pores are naturally deep and prominent, but as my skin texture looked a little more refined, my pores felt relatively less noticeable too. This is an impression based on my own experience using it.

Skin changes and how a product feels can vary by skin type. If you have sensitive skin, it may be best to watch for reactions when using it alongside other ingredients.

I noticed changes in my tone and texture after about two weeks, but I felt it was important to keep using it and observe my own skin’s response.
