Glutathione serum for sensitive dry skin: HEEDA All-in-One Serum
In short
HEEDA Glutathione All-in-One Serum is a Korean skincare serum I used morning and night while my skin felt sensitive, dry, and oily. Its watery, fast-absorbing finish left a subtle glow without much stickiness, though skin results can vary.

What does HEEDA Glutathione All-in-One Serum feel like?

When I first tested it on the back of my hand, it had a watery texture that flowed lightly. It absorbed relatively quickly once it touched my skin, and it did not feel very sticky even immediately after application.


I prefer a fast-absorbing serum over layering many steps, so this texture suited me well. I also felt comfortable using it before makeup.

How did I use it morning and night?

I used 2–3 drops at the serum step in the morning and evening. After lightly patting it in with my hands, it felt as though it adhered to my skin and left a hydrated, clear finish.

After a few minutes, it left a subtle glow rather than a surface-only oily shine. When I used it before makeup, my makeup also seemed to apply naturally.


Did my skin change during a sensitive, dry period?

I used it during cold weather, when my skin was sensitive and I was concerned about both dryness and oiliness. With continued use, my skin texture felt a little smoother, and stress-related blemish marks also seemed soothed for me.

The product states that it contains niacinamide and glutathione. However, skin changes and potential irritation can vary depending on your skin condition.


Who might it suit?

It may be worth considering for anyone who wants to use a lightweight serum morning and night, with a non-sticky finish and subtle glow. I found it relatively comfortable even on sensitive days, but sensitivity varies from person to person.
