Glutathione glow serum for sensitive oily skin: HEEDA
In short
HEEDA Glutathione High-End Glow Radiance Serum is a 30ml brightening serum I tested in Korea for one week on sensitive, oily skin prone to breakouts from heavy products. It absorbed lightly before sunscreen and in my nighttime routine without irritation, though I felt tone care would require consistent use rather than delivering an immediate change.

What are the texture and absorption like for HEEDA’s glow serum?
After summer, my skin tone felt dull and uneven, so I started using it. Vitamin C serums had felt too stinging for me, and I was looking for a gentle brightening product.

At first, I worried that the non-clear formula might leave color on my skin, but it absorbed cleanly when I patted it onto the back of my hand and my face. It had almost no stickiness and left a hydrated finish, so it felt less burdensome even on my skin, which tends to break out when I apply heavy or oily products.
How did I use it in the morning and at night?
After cleansing, I smoothed my skin with toner, lightly patted the serum over my whole face, and finished with a moisturizer. In the morning, I applied a thin layer right before sunscreen, and it adhered without my makeup looking patchy or pilling. The dropper bottle also made it easy to control the amount.
Did I notice a tone change after one week?
Rather than expecting short-term whitening, I hoped my complexion would gradually look clearer with continued use. After a few days, my complexion and skin texture looked a little brighter, and my skin seemed less dry. Faint acne marks and dark spots also seemed to fade little by little, but this was my personal experience; I felt that pigmentation care does not end in a day or two and requires consistency.
Was it suitable for sensitive skin?
Throughout the test period, it absorbed lightly without irritation or breakouts. It may be useful to consider if vitamin C irritation feels burdensome or if you are looking for a tone-care serum to use morning and night without stickiness. However, it may feel disappointing if you expect an immediate effect.
What stood out for the price?
At ₩14,900 for 30ml as written by the tester, it felt reasonably priced for a brightening serum used every day. Its quick absorption and versatility for both daytime and nighttime use were especially convenient.
