Well, generally speaking, hollow eye can be annoying to many people. And when you get it, it will cause the dark eye circles. Also, sometimes, it will just make me look very tired. Anyway, it is bad to have it. According to some doctors, plastic surgery can be good. But on the other hand, some people insist on Juvederm and Restylane injections, which are thought as the safest, most effective ways. But also, fat transfer is another good option. It all depends on your own decision. So you can just console it with your eye doctor.
I would like to provide several suggestions for you. Firstly, you can use a filler to fill the hollow, such as hyaluronic acid or fat. secondly, you can apply something containing vitamin C to reduce the dark circle which can develop into hollow. Finally, you can take a small surgery to restore your loose skin under your eyes, because the loose skin under your eyes can produce hollow.
You should use to adopt the moisture eyes cream on the eyes surrounding part to make the skin of the eyes look elastic and moisture. Then you could do the makeup to make the hollow eyes not look that obvious. Using the eye shadow can you cover the hollow eyes. At the same time, you will look beautiful and charming at the eyes.
