Glutathione glow serum for dull skin: HEEDA High-End Glow Serum
In short
HEEDA Glutathione High-End Glow Serum 30ml is a watery facial serum I used morning and night in Korea. It spread quickly and left a subtle hydrated glow without lingering stickiness, though sensitive skin should be patch-tested first.

As I entered my 30s, I became more conscious of uneven skin tone and small dark spots, so I tried a brightening functional serum suitable for daily use. This is HEEDA High-End Glow Serum 30ml.

What ingredients does it contain?

It contains glutathione 500ppm and niacinamide, along with kojic acid, vitamin E, and golden root extract. The product information says a liposome method was applied to the glutathione.
What is the texture and application like?

My favorite feature was its watery texture. It was light enough to run when I dispensed it onto the back of my hand with the dropper, and it spread widely over my skin as well.

I tend not to reach for serums that are thick or stay sticky for a long time in the morning, but this one absorbed lightly, so it felt less burdensome. After absorption, it left a subtle hydrated glow rather than an oily shine.

How did I use it?

After cleansing, I smoothed my skin with toner and used it at the serum step. I quickly spread an appropriate amount over my whole face and patted it in lightly, then applied lotion or cream; in the morning, I followed with sunscreen.

Did it sting?
I used it in both the morning and evening without any stinging or irritating sensation. Skin reactions vary, though, so if you have sensitive skin, it would be best to test a small amount first.

Is it suitable as a lightweight glow serum?

For me, since sticky or heavy skincare feels burdensome, the watery application was its biggest advantage. I was also happy with the hydrated glow it left after absorption, so I have been consistently using it in my morning-and-night routine lately.
