Potato is a starch-rich food, and there are no experiments to show that potatoes can remove dark circles. There are many reasons for dark circles, which can be categorized into 4 types, and corresponding countermeasures can be taken according to the different types of dark circles. 1. Pigmented type: mainly manifested as the orbital rim arc gray or brown skin, mainly due to excessive precipitation of melanin in the skin under the eyes. You can prevent the aggravation of this type of dark circles by going out and wearing a hat, playing umbrellas and other means of sun protection. 2. Vascular type: manifested as the inner side of the lower eyelid greenish-purple. This is mainly due to excessive eye use, poor rest and other factors that lead to poor blood circulation around the eyes, local venous blood flow obstruction. It can be improved by taking sufficient rest. 3. Structural type: Congenital tear trough caused by orbicularis oculi muscle ligament pulling, visually similar to dark circles. This type of dark circles usually requires surgical improvement. 4. Mixed type: All of the above factors are present. Patients who wish to improve their dark circles are advised to visit a regular medical institution and choose the appropriate treatment plan after an interview with a specialist.
