Dark spot serum for dry sensitive skin: HEEDA Glutathione Serum
I used HEEDA Glutathione High-End Glow Radiance Serum morning and night for dark spots, dryness, and a dull-looking complexion in my 40s. Its watery texture felt light and non-sticky, with no stinging on my sensitive skin; it did not erase my dark spots immediately, but my skin looked a little more even.
