Why I looked for a glutathione serum after outdoor activities

Because I spend a lot of time outdoors and am often exposed to UV rays, my face seemed to be getting darker, so I looked into brightening serums. I then received HEEDA Glutathione High-End Glow Radiance Serum to try.


How did the texture and bottle feel?

The yellow packaging and dropper bottle felt neat, and it was easy to dispense the amount I needed. The texture was not runny like water, but it did not feel excessively heavy.

When I spread it over the back of my hand and my face, it absorbed relatively quickly and felt hardly sticky. Afterwards, my skin felt soft with a subtle glow.

How I used it morning and night


After toner, I spread two to three drops over my entire face. In the morning, I applied sunscreen after the serum, and I used it in the same order at night.

When I used it in the morning, my skin felt less dry and more comfortable through the day. I do not usually prefer sticky textures, so its lightweight finish suited me well.

What I expected from its brightening claims

The product information described glutathione and niacinamide, along with two-week clinical results related to blemishes and pigmentation. Since I had been concerned about my skin tone and blemishes after outdoor activities, I plan to keep using it and watch for changes.


My honest verdict so far

What I noticed immediately was the moisture and lightweight absorption. I have not yet been able to confirm longer-term changes in skin tone or pigmentation, so I plan to continue using it and keep an eye on them.
