Dark circles under the eyes are commonly caused by thin translucent skin, blood pooling, hyperpigmentation, volume loss, and lifestyle factors like poor sleep or dehydration. Topical peptides may help by modestly boosting collagen production, strengthening the skin barrier, and reducing inflammation, though results are typically subtle and appear over 6 to 12 weeks. Peptides work best as part of a complete routine that includes daily sun protection, hydration, retinoids, and antioxidants.
