## 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.
