Its light, low-tack finish made it easy to use before makeup, and it left my skin feeling hydrated with a subtle glow. ## Good to know - **Product**: HEEDA Glutathione High-End Glow Serum 30ml - **Key ingredients**: Liposome glutathione, niacinamide - **When used**: Morning and night - **Where to buy**: Search “HEEDA serum” on Coupang *Prices as written by the tester on Sep 3, 2026 · not updated automatically* ## Why did I use it for acne marks and uneven-looking skin tone? ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare-b905/heeda-glutathione-serum-daily-tonecare-01-1p54j-1200.webp) After my acne subsided, I was concerned that red marks and dark spots left around my cheeks and jaw made my skin tone look uneven. Rather than expecting a quick change, I added it to my daily routine to care for my skin tone and the appearance of dark spots. ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-02-aidn9-900.webp) Another reason I chose it was that it is a functional brightening serum containing liposome glutathione and niacinamide. ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-03-1ntor-900.webp) ## Is the texture sticky? ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-04-57ibe-900.webp) When I dispensed an appropriate amount and spread it with a rolling motion, it applied smoothly without feeling stiff or pilling. After it absorbed, it felt more hydrating than as though the serum was sitting on my skin, and I found it less sticky, with less hair clinging to my face. ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-05-170m2-900.webp) ## Can I use it before morning makeup? ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-06-15530-880.webp) I used it in my morning skincare routine as well as at night. In the morning, I applied only a thin layer as needed and let it absorb fully before using moisturizer and sunscreen, and the following steps did not feel especially prone to pilling. At night, I adjusted the amount and applied it a little more generously. ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-07-xvy6c-900.webp) ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-08-gjk4m-900.webp) ## How did my skin look right after applying it? ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-09-199u1-900.webp) After it absorbed, my skin texture felt hydrated and looked smoother, with a subtle glow. It looked more like added moisture than an oily shine, and I could see a hydrated glow on my cheeks and cheekbones when they caught the light. ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-10-bcbji-900.webp) ## What should sensitive skin keep in mind? ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-11-cw5rj-900.webp) The product information stated that its primary irritation test for sensitive skin recorded an irritation response of 0.00 and no adverse reactions such as erythema, swelling, or itching. Skin reactions vary by person, though, so if your skin is sensitive, it would be best to test a small amount first. I did not experience stinging or discomfort while using it morning and night. ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-12-181vp-900.webp) ## How did I layer it? ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-13-ejqcb-900.webp) After cleansing, I refined my skin texture and applied one thin layer over my whole face. Once it had absorbed fully, I applied a small additional amount around my cheeks and jaw, where red marks or dark spots were more noticeable. Rather than applying a large amount at once, applying a thin layer first and adding more where needed worked well for me. ![Glutathione brightening serum for uneven tone: Heeda Glow Serum](https://img.superchart.com/images/heeda-glutathione-serum-daily-tonecare/heeda-glutathione-serum-daily-tonecare-14-m2ojr-900.webp) I do not think acne marks disappear overnight with a single cosmetic product. Still, its light, low-tack feel made this a serum that was easy to keep in my morning and evening routine. ## Products - Heeda Glutathione High-End Glow Serum 30ml — HEEDA - 쿠팡 — ‘희다 세럼’ 검색 후 구매 --- Superchart · https://superchart.com/en/@cotton-pad-corner/heeda-glutathione-serum-daily-tonecare-b905/ · https://superchart.com/llms.txt
