The serum spreads in a watery layer with little stickiness, which made it easy to use while caring for a child, and the writer felt less tightness under the skin and less base makeup sliding off. For anyone who wants a light, non-sticky glow serum, HEEDA is an easy daily pick. ## Good to know - **Product**: HEEDA Glutathione High-End Glow Radiance Serum - **Time used**: About 1-2 weeks - **When used**: Morning and evening routine - **Price**: Around the high 10,000 won range on the official store (as noted by the writer) - **Texture**: Watery, runny texture, as described by the writer - **Price reference**: ₩10,000 ≈ $7.4 (2026-09-15) *Prices as written by the tester on Dec 1, 2025 · not updated automatically* ## How does the HEEDA glutathione serum feel going on, and how fast does it absorb? ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-02-1qmnr-788.webp) ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-03-184nc-732.webp) Bothered by a dull skin tone and tightness underneath, I used HEEDA High-End Glow Radiance Serum for about 1-2 weeks. It had a watery texture that flowed like water, and once spread on my face it felt like it set in relatively quickly. ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-04-1nqid-765.webp) ![HEEDA High-End Glow Radiance Serum main product image](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-01-iog1g-800.webp) I worried a glow serum like this might feel heavy or sticky, but I felt less stickiness and less of that stuffy feeling. I used it with a dropper, about 2-3 drops at a time, and even when I picked up my child or lay down right after applying, less of it seemed to transfer off my face, which was convenient. ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-05-v2cyd-900.webp) ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-06-1lg7e-900.webp) ## Is HEEDA High-End Glow Serum easy to use morning and night? ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-07-11vq8-900.webp) I used it simply in both morning and evening routines — toner, serum, then cream. In the mornings I applied cushion foundation right after the serum, and there wasn't much makeup slippage; my skin also seemed to have a subtle glow coming from underneath. ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-08-l1rz6-900.webp) ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-09-aixdt-900.webp) ## What changed in the writer's skin after about 2 weeks? ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-10-10api-900.webp) The tightness I used to feel around my cheeks and mouth after cleansing decreased, and the surface oiliness that used to shine felt reduced too. My overall skin tone didn't dramatically brighten, but it looked a bit more even and clear. ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-11-13tof-900.webp) ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-12-7kbkb-900.webp) The minor blemishes around my cheeks and eye area also looked slightly faded, and my base makeup applied thinner and smoother. That said, this is just the change I felt in my own conditions. ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-13-14j2d-900.webp) ## Who is this watery glow serum best for? ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-14-1b5nk-900.webp) ![Glutathione glow serum tested 2 weeks: HEEDA High-End Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-two-week-glow/heeda-glutathione-serum-two-week-glow-15-y90qj-900.webp) This could be useful for people whose skin is dry underneath but who find heavy, sticky serums uncomfortable, for parents whose schedule makes a long skincare routine difficult, and for anyone bothered by makeup lifting during the day. As the writer mentioned, the price on the official mall was in the upper ₩10,000s. ## Products - HEEDA High-End Glow Radiance Serum — HEEDA - 1만 원대 후반 정도(공식몰 기준, 작성자 언급) (Dec 1, 2025) - 약 1~2주, 아침·저녁 - 네이버 — '희다 세럼' 검색 후 구매 --- Superchart · https://superchart.com/en/@glossy-keyboard/heeda-glutathione-serum-two-week-glow-1695/ · https://superchart.com/llms.txt
