## In short

HEEDA Glutathione High-End Glow Serum is a Korean skincare serum I used for two weeks while concerned about redness, faint dark spots, and an uneven-looking skin tone. Its watery texture absorbed lightly, and I personally found that my redness felt calmer, with a subtle glow and smoother makeup application.

## What skin concerns did I use it for?

Recently, I had been concerned about redness, faint dark spots, and an uneven-looking skin tone, so I used it hoping for both brightening and glow care. Rather than layering several functional products, I wanted to try caring for my skin with just one serum.

## What were the texture and absorption like?

When I dispensed it onto the back of my hand, it had a clear, transparent, water-like texture. It absorbed quickly when spread over the skin, felt minimally sticky, and left a slight glow afterward.

I do not like a greasy feel and tend to have sensitive skin, but I was able to use it lightly without any breakouts during the test. I used it lightly in summer, and in winter I used it as a serum to help with inner dryness.

## How did redness and skin appearance change after two weeks?

After using it consistently for two weeks, I personally felt that my redness became more comfortable and that my skin had a subtle glow. My overall skin tone looked a little more even, and the faint dark spots also seemed slightly less distinct.

My skin texture felt smoother and more refined without an oily feel, and I found that makeup applied better when I used it in the morning. However, these changes are my personal experience on my own skin.

## Would I keep using it as a daily serum?

Its non-sticky water-glow texture made it easy to use every day without feeling burdensome. If you are also concerned about redness, skin tone, and a glowy finish, you may find my personal experience useful.
