Treating dark circles under the eyes typically involves addressing underlying causes such as genetics, aging, allergies, or lifestyle factors. Topical treatments containing ingredients like vitamin C, retinol, peptides, and hyaluronic acid can help improve skin texture and reduce pigmentation. For more stubborn dark circles, dermatological procedures such as chemical peels, laser therapy, or dermal fillers may be recommended to enhance skin tone and volume. Adequate sleep, a balanced diet, and managing allergies can also complement treatments, promoting healthier skin and reducing the appearance of dark circles over time. Consulting with a dermatologist can help determine the most effective approach based on individual skin type and specific concerns.
