Under-eye bags are protruding and dark circles are flush with the skin. Dark circles are localized brownish-blue and black pigmentation around the eyes caused by congenital genetic factors or acquired fatigue, late nights, and natural aging, mainly concentrated on the lower eyelids, and in severe cases, can also involve the upper eyelids and other parts of the eyes, forming a circle like a circle. There are three types of dark circles, namely venous stasis type, congenital pigmentation type and aging type. Under-eye bags are the result of bloated lower eyelid tissues combined with the formation of sagging skin on the lower eyelid, which hangs in a band-like pattern. Patients with visible bags under the eyes have heavier dark circles through the eyes. The treatment differences between the two are also greater. Dark circles are mainly treated by topical medications to improve vascular circulation, oral whitening drugs, and then combined with pigmentation and laser treatment. Under-eye bags mainly rely on surgical treatment.
