Glutathione serum for combination-oily skin: HEEDA Even & Glow Serum
In short
I tested HEEDA Glutathione Even & Glow Serum morning and night on combination-oily skin before completing two weeks of use. Its watery, low-tack texture worked comfortably under makeup, but it is too early for me to judge any brightening change.

How did the texture feel on combination-oily skin?
I tried this serum because I was concerned about winter tightness beneath the skin, redness, dark spots, and rough texture. My skin is combination-oily, so I do not prefer sticky formulas, but this one had a clear, watery texture that did not feel burdensome even when layered several times.
I dispensed an appropriate amount with the dropper and massaged it in. It felt like it absorbed lightly, and the scent was not overpowering, so it was easy to use daily.
How did my skin and makeup feel after morning-and-night use?
When I used it morning and night, my skin felt smooth and moisturized. Even when I applied makeup after my skincare, there was little pilling, so I felt that my makeup sat well.
The product was described as containing glutathione and niacinamide, but I have not used it long enough yet to judge any brightening-related changes.
What about the price and would I repurchase it?
At the time of writing, one bottle was ₩14,900. I did not feel that the price was burdensome for the volume, and I would consider using it again after trying it for about two more weeks.
