Types of Under-eye Dark Circles
Vascular dark circles
These appear as pink, purple, or blue discoloration under the eyes along with puffiness and in some cases veins also become visible. They are caused by thinning of the facial skin under the eyes leading to fluid retention and reduced blood flow.
Pigmented dark circles
These are usually brown discoloration under the eyes that can be due to extra melanin production and uneven pigment distribution.
Structural dark circles
These appear because of the shadowing effect as a result of skin laxity, eye bags, or fat loss beneath the skin of under eyes.
Mixed dark circles
These are caused by a combination of vascular, pigmentation, and structural features.
