Its rich texture felt comfortable under makeup with little stickiness, though daily twice-a-day use could finish a bottle in about a month. ## Good to know - **Product**: HEEDA Glutathione Brightening Tone Care Glow Serum - **Volume**: 30ml - **Use period**: 2 and 3 weeks mentioned in the review - **How I used it**: One or two pumps morning and night - **Where to buy**: Search “HEEDA serum” on Coupang *Prices as written by the tester on Aug 29, 2026 · not updated automatically* ## Was it low in stickiness before morning makeup? ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-01-1t5ki-1200.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-02-1w7gf-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-03-12p2x-900.webp) Previous brightening serums felt sticky or tacky when I applied makeup, so I used them only at night. With this product, I spread one or two pumps over my whole face after toner and skin in the morning, and found it relatively comfortable under makeup. ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-04-f2xds-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-05-1iv3s-900.webp) At night, I used the same amount, spreading it more slowly as if massaging it in and finishing with cream. I felt that my skin stayed moisturized until the next morning. ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-06-14yla-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-07-bcqlw-900.webp) ## How did the texture and bottle feel? ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-08-14gm5-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-09-afieg-900.webp) The serum in the 30ml bottle looked dark brown, and it felt concentrated enough that even a nail-sized amount could be spread across my face. I adjusted the amount with one or two pumps. ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-10-13roo-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-11-67iz2-900.webp) The dropper-pump bottle made it easy to dispense a measured amount. It initially felt like a rich texture, then seemed to melt along my skin texture when rubbed in; absorption felt faster when I applied it as if massaging it in. ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-12-1c4k2-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-13-kix7p-900.webp) ## How did my skin seem after two to three weeks? ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-14-1h929-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-15-1wf7c-900.webp) After using it, I felt that my skin tone looked brighter and more lively. My previously dull-looking face seemed to have a natural glow, and I felt that the brighter-looking tone also helped when applying makeup. ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-16-103ke-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-17-10u23-900.webp) Liposomal glutathione and niacinamide were mentioned as key ingredients, and while using it, I had the impression that my skin texture looked more refined and clearer. This is my personal observation from using the product. ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-18-1t76k-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-19-4qiak-900.webp) ## What was the downside for daily use? ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-20-8c6cf-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-21-czh7y-900.webp) I counted its low stickiness and ease of use both morning and night as advantages. However, because it is 30ml, I wrote that using it every day in the morning and evening could use up about one bottle a month. ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-22-l7bmp-900.webp) ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-23-1l5gt-900.webp) The original post did not state a specific price. I did not feel that the cost was too burdensome and plan to repurchase it. ![Glutathione serum for dull skin, AM/PM test: HEEDA 30ml](https://img.superchart.com/images/heeda-glutathione-daily-serum-tonecare/heeda-glutathione-daily-serum-tonecare-24-4ztoz-900.webp) ## Products - HEEDA Glutathione Brightening Tone Care Glow Serum 30ml — HEEDA - 본문에 2주 및 3주 사용 언급 - 쿠팡 — '희다 세럼' 검색 후 구매 --- Superchart · https://superchart.com/en/@coffee-and-daylight-2/heeda-glutathione-daily-serum-tonecare/ · https://superchart.com/llms.txt
