Lacrimal groove is a concave groove of the lower eyelid near the nose, starting from the inner corner of the eye. It is caused by atrophy and sagging of muscles under the orbit. Generally congenital, it is not obvious when you are young, but it will be more obvious after staying up late and aging.
The bags under the eyes are the skin under the eyes that is slack, aging, losing elasticity, and the muscles droop, generally protruding outward in a triangle shape, while the lacrimal groove is concave. Although they are all under the lower eyelid, they look different.
The eye bags are triangular protrusions, and the lacrimal groove is splayed. The lacrimal groove is closer to the nose, in the middle and lower parts of the nose and eyes, while the pouch is just below the lower eyelid, next to the lower eyelid and away from the nose.
Moreover, the color of the eye bags is relatively dark, and there is no difference between the color of the lacrimal groove and the skin color. The only difference is that it is concave, but the wrinkles under the eyes and under the eyes will get deeper and deeper.
Bags under the eyes are mainly formed the day after tomorrow, such as irregular work and rest, aging, improper makeup massage and so on. Lacrimal groove is generally congenital, especially for people with thin skin around the eyes and older people.
