Its watery texture settled quickly and felt comfortable under makeup; on my sensitive skin, it was generally easy to use, though changes in tone and texture were personal observations. ## Good to know - **Product**: HEEDA Glutathione High-End Glow Radiance Serum - **Testing period**: About 2 weeks - **Skin type**: Sensitive skin that can break out with new products - **How I used it**: Layered over the face and dry areas after toner - **Where to buy**: Search “HEEDA serum” on Coupang *Prices as written by the tester on Dec 8, 2025 · not updated automatically* ## How did the texture and absorption feel after two weeks? ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-01-1a58y-900.webp) ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-02-1166z-900.webp) I used it for about two weeks when I was paying attention to inner glow care after being told that my skin looked dull and tired. The water-glow texture spread lightly in my hands and settled relatively quickly without feeling like it sat on the surface. ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-03-pbfrs-900.webp) Rather than the usual oiliness of a serum, it gave my skin a subtle, water-filled-looking sheen. It was also nearly fragrance-free, so it was easy to add to my existing skincare routine. ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-04-1py5y-900.webp) ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-05-1yeqy-900.webp) ## Could I use it on sensitive skin and before makeup? ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-06-2w4zf-900.webp) New products can sometimes cause breakouts for me, but this one was generally comfortable to use without major irritation. When I applied sunscreen and cushion foundation after it in the morning, I felt that lifting around my nostrils and the emphasis on dry flakes were less noticeable than before. ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-07-1gh5x-900.webp) ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-08-18ykv-900.webp) Even when layered, it did not pill much, and what I liked most was how light it felt before makeup. ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-09-t7nrg-900.webp) ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-10-glo30-900.webp) ## How did I layer the serum? ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-11-1wrqc-900.webp) It comes with a dropper, so I spread a thin layer over my whole face after toner. I applied a little more to my dry cheeks and around my mouth, then finished with cream after the serum at night. On nights when I wanted more moisture, I layered it twice. ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-12-109k3-900.webp) ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-13-1w2oo-900.webp) ## How did my skin tone and texture feel after two weeks? ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-14-1wpep-900.webp) The following morning, my skin felt less rough and its texture seemed smoother. After about two weeks, I did not feel that it had become dramatically brighter; instead, areas that had looked dull seemed more even, giving my overall complexion a slightly more uniform appearance. ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-15-uamxv-900.webp) ![Glutathione glow serum for dull skin, 2-week test: HEEDA](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-16-1clqy-900.webp) Pigmentation marks beside my nose and on my chin also looked less pronounced, but these were personal changes I noticed based on my own skin condition. It may be worth considering if you prefer a light, watery feel over a sticky or heavy serum. ## Products - HEEDA Glutathione High-End Glow Radiance Serum — HEEDA - 약 2주, 아침저녁 - 쿠팡 — ‘희다 세럼’ 검색 후 구매 --- Superchart · https://superchart.com/en/@browser-lipbalm/heeda-glutathione-serum-two-week-glow-a08d/ · https://superchart.com/llms.txt
