Glutathione serum for dull-looking skin: HEEDA High-End Glow Serum
In short
HEEDA High-End Glow Serum is a glutathione serum I used morning and night for several days in Korea. It absorbed quickly with little stickiness and made my skin look more hydrated and put together on dull-looking days, though results may vary by person.

What are the texture and absorption like?

I tend not to reach for products that feel heavy or sticky, so I prefer serums that feel hydrating but absorb refreshingly. This had a fresh serum texture—not a runny, watery type and not a thick cream type.

It spread lightly and absorbed fairly quickly, without leaving much of a sticky feeling on the surface. I also did not find the feeling of my hair sticking to my face after applying the serum particularly bothersome.
How did my skin look after using it?

After it absorbed, it gave my skin a natural sheen that felt hydrated rather than an oily shine. My face seemed a little more put together and brighter than before using it, and I was especially satisfied on days when my skin looked dull.

How skin looks can vary from person to person. Still, even as someone using a glutathione serum for the first time, I did not find the application experience difficult.

How did I use it morning and night?

In the morning, I applied one light layer after toner, then used cream and sunscreen. The products did not noticeably pill afterward or feel overly heavy, so it was fine to use in my morning skincare routine.
At night, I layered it once or twice on days when I wanted more hydration. Rather than applying a lot at once, I personally found it worked better to let on a thin layer absorb before applying another layer.

Who might like this serum texture?

It felt easy to use if you are concerned about skin looking dull but find heavy, sticky serums burdensome. Its refreshing absorption and easy morning-and-night use were what stood out most to me.
