Does this serum actually work for dark circles, and how long does it take?

Yes — the formula includes a clinically studied bioflavonoid-peptide complex called Haloxyl, which combines Chrysin and N-Hydroxysuccinimide with peptides specifically to address the discoloration that causes the appearance of dark circles. Chrysin helps break down the hemoglobin that accumulates in the under-eye area and contributes to darkness. N-Hydroxysuccinimide supports the skin’s natural process of clearing that pigment. Many users report visible lightening within one to two weeks of consistent twice-daily use. Results can vary depending on the cause of dark circles — those caused by vascular pooling or hemoglobin breakdown typically respond best to this type of formula, while dark circles caused by deep-set bone structure or genetic pigmentation may see more modest improvement over a longer period.
