Glutathione serum for combination skin, tested 2 weeks: HEEDA
In short
HEEDA Glutathione High-End Glow Radiance Serum is a lightweight brightening serum I tested for about two weeks on combination skin with dry cheeks and an oily T-zone. It absorbed quickly without much stickiness, and while the change was not dramatic, my skin tone looked more even and cheek spots seemed slightly lighter.

Was the texture lightweight for combination skin?

My cheeks are dry while my T-zone gets oily easily, so with combination skin, I tend to be careful with heavy or sticky products in case they cause breakouts. This serum had a thin, water-glow texture that sat well on my face rather than running off.

After application, it absorbed as lightly as water and left almost no stickiness. As someone who dislikes residue from skincare steps, I was pleased with how clearly it settled into the skin.


How did my skin tone change after two weeks?

I used it consistently for about two weeks. Rather than seeing a completely dramatic brightening change, I felt that my skin looked clearer and more even overall. The spots on my cheeks also seemed very slightly lighter, and my base makeup appeared to adhere better than before.

My skin looked less dry and dull, giving the impression that it looked healthier. However, these were changes I felt on my own skin.

Did it cause irritation or oiliness during use?

For me, it did not feel as though my oil-and-moisture balance was significantly disrupted, and I had no breakouts or stinging while using it. I plan to keep using it when I am looking for a lightweight brightening serum.


What ingredient combination did it have?

The combination I noticed in this product was glutathione and niacinamide. The ingredient composition looked good to me, so I decided to try this serum in addition to the simply formulated products I usually use.
