It depends on what you mean by "hollow eyes" and hard to give any real recommendations without a photo. Filler is a very common and suitable fix for many people with hollow under eyes, however it is not appropriate for everyone. If you are a candidate, a small amount of Restylane could be injected underneath the eyes to give you a more awakened and refreshed look. Results typically last for about 4-6 months and the procedure is quick and painless. I am a New York board-certified dermatologist very experienced in injecting the tear troughs and would be happy to help you.
One has to be more specific or at least show photos. If you mean that the lower lids have depressions underneath them along the lid cheek junction or tear trough region, then perhaps fillers might be helpful.
