In short
HEEDA Glutathione Even & Glow Serum is a skincare serum I used consistently for two weeks on my dry, dark-spot-prone skin in Korea. It felt moisturizing without much stickiness and made my complexion seem brighter, though the dark spots only appeared to fade in my personal experience.

How did it feel on dry skin with dark-spot concerns?


I do not usually change skincare products easily, but when I ran out of my usual product, I tried this serum because I was concerned about dryness as well as dark spots and pigmentation that had appeared during summer and fall. My skin is dry and tends to develop dark spots and melasma that can look pronounced.

Is the texture sticky?


I first tested it on my hand. It had a water-glow texture with a slight yellow tint, and it applied moisturisingly while feeling only minimally sticky. Rather than being completely as light as water, it felt as though it adhered to my skin.

Was the bottle and storage convenient?


It came in a brown dropper bottle, so it was easy to dispense only the amount I needed. Some brightening serums need to be refrigerated, which can make me less likely to reach for them, but this product was stated to be suitable for room-temperature storage, so it was convenient to keep on my vanity. I was also informed that prolonged exposure to light can change its color, but does not affect the product's function.

How was it after two weeks of consistent use?


After applying it consistently for two weeks, the dryness beneath my skin seemed less noticeable, and I felt that my face looked a little brighter. My dark spots also seemed to fade, but that is an observation based on my own experience. My husband used it with me every evening.
