Glutathione serum for dry skin, 1-week test: HEEDA Glow Serum
I used HEEDA Glutathione High-End Glow Radiance Serum for about a week on dry, rough-feeling skin in Korea. Its watery texture absorbed lightly, and while it seemed to ease post-cleansing tightness, longer use is needed to judge changes in pigmentation or skin tone.
