Glutathione glow serum, 1-week test: HEEDA High-End Glow Serum
HEEDA Glutathione High-End Glow Radiance Serum is a 30ml Korean skincare serum I used morning and night for more than a week. Its watery, non-sticky finish was comfortable, and I felt my skin tone and texture seemed better, though I think it needs longer-term use.
