Pure fat protrusion type As the name suggests, it is the type that only has fat protrusion, but no skin laxity. Most of the candidates in this category are young and have bags under their eyes without skin laxity; some of them have family genetic tendency, and the elders in the family had similar situation back then. But do not worry, this is the best solution to the type of bags under the eyes, later we will explain in detail. Loose skin type refers to the type that only has loose skin but no fat protrusion. In this type, the lower eyelid usually does not have much orbital fat, and the orbital septum can still “bind” the fatty tissue, but the skin is indisputably saggy, and the wrinkles on the lower eyelid increase. Mixed type There are also candidates who have the characteristics of the above two types, with both fat prominence and skin laxity, which we call “mixed type eye bags”. This is usually seen in middle-aged and elderly people. It is characterized by laxity and accumulation of skin on the lower eyelid, increased wrinkles, pouching of intraorbital fat, drooping of the outer corner of the eye, and increased curvature of the lower lid margin. Mixed type with tear trough deformity In addition to the above three types of eye bags, there is a very special type. In addition to the characteristics of mixed type bags, this type of patient also has a significant depression of the tear trough. The sunken tear trough often gives a very “bitter” effect and therefore requires targeted special treatment.
