Glutathione serum for dull skin, 2 weeks: HEEDA Glow Serum
In short
I used HEEDA Glutathione High-End Glow Radiance Serum in my morning routine for about two weeks on combination skin that leans dry. Its watery, fast-absorbing texture sat comfortably under makeup, and my complexion looked less dull and more even, though dark spots did not suddenly disappear.

What are the texture and absorption like?


When I first used it, the texture felt thinner and more watery than I expected. It felt closer to an essence than a serum, spreading naturally and absorbing quickly when dropped onto the back of my hand.

After absorption, it left my skin looking moisturized rather than dry. It did not feel very sticky or leave much sitting on the skin, so it was easy to apply lightly.

Does it pill under makeup?


When a serum feels heavy on me, the products I apply afterward tend to pill, but this one felt like it adhered in a thin layer. I had almost no discomfort applying base makeup after using it in the morning.

I could use it without tightness even on dry days, and it felt more like replenishing moisture than adding oiliness, so it was easy to use as a daily serum.

How did my complexion look after two weeks?


After using it consistently for about two weeks, I felt that my skin tone looked more even in the morning mirror than before. Freckles and blemishes did not suddenly disappear, but my overall complexion looked less dull.

When I applied a light layer of cushion foundation, my base makeup also seemed to sit well. The combination of glutathione and niacinamide was another reason I continued using it, since I had been interested in products for improving the look of uneven tone.

What skin condition was it good for?


It suited days when, like me, your complexion easily looks dull and you want light moisture before makeup. I plan to keep using it in my morning skincare step for the time being.
