Glutathione serum for dehydrated skin: HEEDA Even & Glow Serum
In short
HEEDA Glutathione Even & Glow Serum is a 30ml Korean skincare serum I used morning and night for over 10 days during winter. Its watery texture absorbed quickly with little stickiness or hairline residue, though I layered it twice on days when my skin was especially flaky.

In winter, if I do not apply skincare properly after washing my face, the tightness deep in my skin seems to last all day, so I had been paying close attention to hydration care. I received HEEDA Glutathione Even & Glow Serum and used it for over 10 days.



What are the texture and format of HEEDA Glutathione Serum like?

Each bottle contains 30ml, and it came with a dropper. It was described as a serum containing high-purity glutathione and niacinamide, and it was fragrance-free.


When I put it on the back of my hand, it had a watery texture that slipped along the contours of my skin. It felt light to apply rather than thick or tacky.

How did it feel to absorb after over 10 days of use?


As I spread it over my skin, it seemed to adhere and absorb relatively quickly without feeling heavy or sticky. There was little feeling of product sitting on top, and I liked the finish, which looked more like a natural glow than an oily shine.


With sticky ampoules, I find it uncomfortable when fine hairs around my hairline touch my face. This product left less of that residue, so it felt less burdensome to use morning and night.

How did I apply it when my skin was flaky?


My skin felt moisturized with just one layer, but on days when flakiness was severe, I applied two layers. On those days, the hydration seemed to last longer, and my makeup also seemed to apply a little better.

Would I use it again when my skin feels tight underneath?


For me, the moisturizing feel and finish were especially good. On winter days when a heavy, oily texture feels burdensome because of tightness deep in my skin, I had a good experience using this as a lightweight serum.
