Glutathione serum for dull skin: HEEDA High-End Glow Serum
HEEDA Glutathione High-End Glow Serum is a Korean brightening serum I used morning and night for about two weeks for dullness, redness, and small dark spots. Its watery texture felt light and worked under makeup without pilling for me, and while my skin looked more even, that result was personal to my skin condition.
