I liked its watery texture and light, non-pilling feel under makeup, though the tone changes are based on my own short-term experience. ## Good to know - **Product**: HEEDA Glutathione Glow Serum - **Testing period**: 1 week - **Skin type**: Oily T-zone with underlying dehydration - **Where to buy**: Search for “HEEDA serum” on Naver *Prices as written by the tester on Dec 2, 2025 · not updated automatically* ## How did it feel on oily, dehydrated skin? ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-01-18rk6-1200.webp) My T-zone tends to get shiny, while my skin also feels dehydrated underneath, so I often notice tightness and dullness as the seasons change. Since I do not prefer sticky or rich serums, I tested this one mainly for how it spread and whether it felt sticky. ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-02-1p4lj-695.webp) ## Is the texture sticky? ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-03-1kq21-900.webp) It had a watery texture with a yellow tint. On my skin, it felt hydrating rather than running excessively, and it seemed to absorb clearly, so I found it minimally sticky. ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-04-18759-775.webp) ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-05-1i9su-900.webp) The dropper format, which lets me dispense just the amount I need, was convenient too. It also felt light under makeup without pilling. ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-06-6fziy-900.webp) ## How did I use it? ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-07-c789m-504.webp) After cleansing, I smoothed my skin with toner, then dispensed two to three drops with the dropper and spread them over my face. I applied it with a light massaging motion, then cupped and pressed my face with my palms to help it absorb. ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-08-n475t-900.webp) ## How did my skin feel after one week? ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-09-1xxbe-900.webp) For me, before use, oiliness, dryness, redness, and areas of pigmentation made my skin look dull. After one week, my overall tone seemed about a shade brighter, and I felt that my dry, rough-looking skin had a subtle glow. ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-10-1w46b-821.webp) The area around my mouth also seemed brighter than before, so I started wearing a thinner layer of base makeup. Cream and makeup tended to sit well after the serum, so I used it often in my daily routine. ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-11-18s2p-609.webp) ## What ingredients were mentioned? ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-12-zztrr-900.webp) ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-13-tguq1-900.webp) The original post introduced glutathione and niacinamide as key ingredients. However, the assessment of skin changes is based on my observations from one week of use. ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-14-svb26-823.webp) ## Overall: Who might it suit? ![Glow serum for oily, dehydrated skin: HEEDA Glutathione Serum](https://img.superchart.com/images/heeda-glutathione-watery-serum-one-week/heeda-glutathione-watery-serum-one-week-15-1l0nh-496.webp) It may be worth considering if you are concerned about dullness and small blemishes and want a non-sticky serum. For me, the most satisfying points were its watery texture and light feel before makeup. ## Products - HEEDA Glutathione High-End Glow Radiance Serum — HEEDA - 1주일 - 네이버 — '희다 세럼' 검색 후 구매 --- Superchart · https://superchart.com/en/@sponge-case-stories/heeda-glutathione-watery-serum-one-week/ · https://superchart.com/llms.txt
