## In short

I used HEEDA Glutathione High-End Glow Radiance Serum for about 10 days on dehydrated skin that feels tight underneath but gets oily on the cheeks. Its watery, fast-absorbing finish suited a busy childcare routine, though changes in tone and redness were my personal observations.

## How was it after 10 days on dehydrated skin?

While keeping my skincare routine simple during childcare, I was concerned about dull-looking skin, inner tightness, and oily cheeks. My skin is the dehydrated type that often feels very tight underneath, so I used this product for about 10 days while looking for a serum that felt light yet made dryness less noticeable.

## What were the texture and absorption like?

It had such a thin, watery texture that it ran when dropped onto the back of my hand. It absorbed quickly after application, which made it convenient on days when it was difficult to spend much time on multiple skincare steps. There was almost no stickiness, so it felt less like it would transfer to my child when I held them, and I could use it at night without feeling like it stuck to my pillow.

## How did dryness and oiliness feel?

For me, the cheek area that felt tight right after cleansing felt relatively comfortable, and I noticed the fine dryness around my mouth and beside my nose less. After some time, the feeling of surface-only oiliness also seemed reduced, and my skin texture felt smooth and soft. However, these were changes I felt after using it on my own skin for 10 days.

## Was it convenient before morning makeup?

The lightweight texture made it easy to apply in the morning as well. When I put on makeup afterward, it absorbed without feeling like it pilled, and my complexion makeup looked neat. I tend to find layering many products bothersome, so its quick absorption and ease of layering were especially convenient.

## Were there changes in skin tone?

While using it, the redness on my cheeks seemed to flare up less than before, and dullness also felt slightly less noticeable. With less inner tightness, I also got the impression that my overall tone looked relatively even and clear, but this is a personal observation based on my skin condition.

## Who might like this kind of serum?

This may be a useful texture reference for people whose skin is dehydrated underneath but who want to avoid heavy, sticky serums, as well as those looking for a lightweight formula they can apply quickly in a busy routine.
