Glow serum for dehydrated-oily skin: HEEDA Glutathione 30ml
In short
I used HEEDA Glutathione High-End Glow Radiance Serum 30ml morning and night for one week on dehydrated-oily skin. Its thin, lightweight texture sat well before makeup, though any change in my skin tone was only my personal impression.

How did it apply on dehydrated-oily skin?

As the seasons changed, my complexion looked duller and faint dark spots seemed more noticeable, so I tried this brightening serum. I usually find sticky or heavy textures difficult to use consistently on my dehydrated-oily skin, but this serum felt thin and light, with a water-glow texture.

When I applied two to three drops at a time, it absorbed relatively quickly and did not feel like it sat on top of my skin. It did not feel irritating even when layered, and the scent was not strong.

Did it pill before makeup?

After letting it absorb on the back of my hand and face, it felt like it adhered transparently. It seemed to absorb quickly after application, so there was little pilling when I used it before makeup, and it was easy to use both morning and night.

What were the bottle and application method like?
At 30ml, it was a size that fit in one hand. The dropper made it easy to dispense only what I needed, and I thought it would be fine to pack for travel because there was less concern about the contents spilling.

How did my skin look after one week?

After using it consistently for one week, my skin tone looked brighter than before, and my makeup looked a little more even and radiant. The faint pigmentation around my lower face also seemed slightly lighter, but that was my personal experience.

When I used it after morning cleansing when my skin felt tight, it felt hydrating. The finish was closer to a subtle glow than a surface-level shine. It felt light enough for daily use on dehydrated-oily skin that finds oily serums burdensome.

What ingredients and usage context were noted?

According to the original post, it was described as containing glutathione and niacinamide. I sometimes mix niacinamide products with other skincare products, but I used this one on its own.
