Glutathione serum for dull skin: HEEDA Even & Glow Serum
In short
HEEDA Glutathione Even & Glow Serum is a brightening serum I tested at home in Korea for about a week. Its watery glow texture felt fresh and wore well under makeup, and my skin tone seemed more even, though dark spots did not disappear completely.

What are the texture and application like for HEEDA Glutathione Serum?
I tried HEEDA Glutathione Even & Glow Serum because my skin tone tends to look dull during dry seasons. The mustard-yellow bottle has a dropper, which made it easy to dispense.

It had a watery glow texture that was neither runny nor overly sticky. It spread smoothly over my skin and felt like it absorbed fresh, without much heaviness.

Does it pill when used before makeup?
I did not notice any pilling when I applied it in the morning and then put on makeup. It left a subtle glow on my skin, and my foundation seemed to adhere better.

The moisture also lasted relatively long on the back of my hand, with a non-sticky finish. The scent was not strong, so I found it easy to use both morning and night.

Did my skin tone change after one week?
After using it for about a week, my skin texture felt smoother and my overall skin tone seemed more even. It looked less dull and had a subtle glow.

However, my dark spots did not disappear completely. I did not experience breakouts or irritation while using it, but that observation is limited to my own experience.

When was it good to use?
I found it good for days when a heavy brightening serum felt burdensome, or for applying lightly during dry seasons. I plan to keep watching for changes with continued use.
