It felt light, absorbed without stickiness, and seemed to reduce post-cleanse tightness, but I think it is too early to judge any tone change. ## Good to know - **Product**: HEEDA Glutathione Brightening Tone Care Glow Serum, 1 count, 30 ml - **Test period**: 3 days, morning and night - **Skin type**: Sensitive skin - **Where to buy**: Search “HEEDA serum” on Coupang *Prices as written by the tester on Sep 3, 2026 · not updated automatically* ## Was there any irritation after using it on sensitive skin for three days? ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-01-1bcug-1200.webp) I have sensitive skin and am concerned about tightness after cleansing, a dull complexion, and dark circles. Because sticky serums have sat on top of my skin before, I had been skipping the serum step and using only cream. ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-02-1fog6-966.webp) I worried that a new product might sting or cause redness, but I did not notice redness or irritation while using it morning and night for three days. Still, this is only my personal experience over a short period. ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-03-d7xkn-966.webp) ## How are the texture and stickiness? ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-04-1x3zn-966.webp) It has a watery texture, so it felt light when I dispensed it onto my hand and absorbed quickly after application. There was none of the stickiness I had worried about most, and my skin felt soft after it absorbed. ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-05-1ktfa-966.webp) When I looked up the ingredients, I found liposomal glutathione and niacinamide. Since I had concerns about my skin tone, having both ingredients was one reason I chose it. ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-06-ajh8q-966.webp) ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-07-1li1o-966.webp) ## How did it feel before makeup and after cleansing? ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-08-1x16k-966.webp) The first thing I noticed was less tightness after cleansing. Before, my skin felt tight enough that I had to apply something immediately, but that feeling was reduced after using it. When I applied lotion after the serum, the lotion also seemed to absorb better. ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-09-o0cs4-966.webp) It is fragrance-free, so I could use it comfortably in the morning. The dropper let me dispense only the amount I needed, and my makeup did not pill when I applied it afterward. ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-10-weh7x-966.webp) ## Can you tell whether skin tone changed after three days? ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-11-1qele-966.webp) My skin seemed to have a glow, and my complexion felt a little brighter. But since it was only day three, I think it is too early to make a definite judgment about tone changes. I ended up using about three full droppers each time, so with its 30 ml size, I may use it up relatively quickly at my rate of use. ![Glutathione serum for sensitive skin, 3-day test: Heeda](https://img.superchart.com/images/heeda-glutathione-serum-lightweight-tonecare/heeda-glutathione-serum-lightweight-tonecare-12-1m8d4-966.webp) For someone like me who hesitated to use serum because of stickiness, it was easy to add to my routine. However, I plan to judge tone changes after using another bottle. ## Products - Heeda Glutathione Brightening Tone Care Glow Serum, 1 count, 30 ml — HEEDA - 3일, 아침저녁 - 쿠팡 — '희다 세럼' 검색 후 구매 --- Superchart · https://superchart.com/en/@powder-box-dusk/heeda-glutathione-serum-lightweight-tonecare/ · https://superchart.com/llms.txt
