Glutathione glow serum 2-week test: HEEDA High-End Glow
In short
This is a glow serum from HEEDA, tested for about two weeks on dry-leaning combination skin in Korea. Its watery, non-sticky finish felt comfortable and seemed to help makeup apply more smoothly, though the tone and spot changes are personal impressions.

What are the texture and absorption like?


When I first tested it on the back of my hand, it had a watery texture that spread thinly with almost no viscosity. After it absorbed, it seemed to leave my skin hydrated without stickiness, with a natural-looking sheen on the surface.

Did it feel manageable on combination skin?

I have dry-leaning combination skin, so heavier serums tend to make the products I apply afterward pill or cause breakouts. This one felt as though it adhered in a thin layer, without pilling; it felt moisturizing while leaving the skin relatively fresh.


It felt nearly fragrance-free. Even on days when my skin felt sensitive from wearing a mask often, I was able to use it comfortably.

How did my skin look after about two weeks?

After a trip to Bali, I was concerned about a duller tone and freckles and dark spots that seemed to darken easily. After using it consistently for about two weeks, I personally felt that my overall facial tone looked more even. It also sometimes felt as though the spots beneath my skin had faded, but that is the writer’s personal experience.


Especially when I used it before makeup, my skin felt hydrated and bouncy, and my makeup seemed to apply better. If you value a lightweight texture and how your skin looks before makeup, this may be a useful reference for its feel in use.
