Its watery, low-tack finish was comfortable, while any changes in tone or dark areas were my personal observations. ## Good to know - **Product**: HEEDA Glutathione High-End Glow Radiance Serum - **Test period**: About two weeks - **How I used it**: A thin layer in the morning and a slightly more generous layer at night - **Skin context**: I was concerned about seasonal dullness and described my skin as on the oily side *Prices as written by the tester on Nov 20, 2025 · not updated automatically* ## Is the watery texture non-sticky? ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow-04d8/heeda-glutathione-serum-two-week-glow-01-uuqjt-1200.webp) ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-02-1ytff-900.webp) When I opened the cap, the formula flowed like water. It felt as though it settled transparently onto my skin, and I did not notice much of the usual serum-like viscosity or heaviness. It also had a slight cooling feel, so it did not feel burdensome to use in the morning. ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-03-zb371-900.webp) ## How did I use it for two weeks? ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-04-y4nra-900.webp) ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-05-zusre-900.webp) During the seasonal transition, my skin looked dull and seemed to be losing firmness, so I used it as a serum for an inner-glow look for about two weeks. Since my skin tends to be oily, I applied a thin layer in the morning and a slightly more generous amount at night, but it still did not feel sticky or heavy. ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-06-1komf-900.webp) ## How did my skin look after two weeks? ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-07-1drqd-900.webp) I prefer a subtle glow that seems to come from within rather than an oily-looking shine, and this product felt closer to that. After about two weeks, my skin looked less dull in the mirror and its texture felt a little smoother. ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-08-9qj0j-900.webp) ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-09-zr6w7-900.webp) My base makeup also seemed to adhere better than before, and I felt that areas that used to become patchy in the afternoon did so less. However, changes in my skin tone or darker areas are observations from my personal use environment. ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-10-ykskw-900.webp) ## Which ingredients and texture stood out? ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-11-1i2r8-900.webp) ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-12-93h9b-900.webp) According to the original product information, high-purity glutathione and niacinamide are presented as the key ingredients. More than the ingredients themselves, the light water-glow texture and low-tack feel stood out most to me. ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-13-dugsf-900.webp) ## Who might it suit? ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-14-117bx-900.webp) ![Glutathione glow serum for dull skin, tested 2 weeks: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-15-1ra62-900.webp) It may be worth considering if you prefer a light serum and want a subtle glow.
