The main pathological changes of skin aging are thinning of skin, decrease of elasticity, decrease of subcutaneous tissue and skin drooping including deep soft tissue structure. The decrease of collagen fiber synthesis and elastic fiber degeneration in dermis are the main reasons for wrinkles, relaxation and sagging caused by skin aging. With the growth of age, due to the degenerative changes of various layers of tissues, there are often different degrees of eyebrow drooping, especially at the outer corner of the eye, which forms the cover or downward movement of the upper eyelid, affecting aesthetics or vision.

There are three ways to improve the corner of the eye, as follows:

1. Sawtooth line suspension. This kind of operation has little injury and quick recovery. Disadvantages are short maintenance time;

2. cut your eyebrows. This kind of operation has little injury and quick recovery. The disadvantage is that some eyebrows need to be cut off in some cases. The lifting range and range of canthus are limited;

3. Endoscopic seamless canthus lifting. Using endoscopic technology, we can face this aging and drooping eye tail very delicately and lift it moderately without leaving any trace. Moreover, because of the effect of eye tail lifting, the loose lower pouch can be tightened at the same time. If liposuction is combined with the eyes, the aging wrinkles of the whole upper and lower eyelids can be faded together, and no scar can be seen at all. It is a multi-purpose anti-aging beauty technology.
