A hyaluronic acid filler would be a great solution. I would never recommend a tear trough implant. Filler is going to look natural and can be put precisely where you need it.
Treatment of tear troughs and hollow eyes
The presence of hollow eyes and tear troughs is usually inherited and does not reflect any aging.
In my opinion, the best treatment would be with a skin filler such as Restylane. These fillers will usually hold up for 1-2 years and can then be repeated or touched up as needed. Would not use a tear trough implant -- ever!! In fact, there is no operation that would work for you for this particular problem.
You will need an expert injector because the skin and other tissues are thin in this area.
One nice and reassuring point: there is an antidote for Restylane (and any other hyaluronic acid filler) -- so if you don't like it, it can be neutralized.
Do your research carefully and find a board certified plastic surgeon who is skilled at these injections.

I strongly advise against a tear trough implant.
Hands down, the best treatment for your issues is under eye filler. The key is finding a highly talented injector to treat this area. Less is more. You have very thin skin here. That is one of the reasons that a tear trough implant is not idea. However, having a small amount of filler in the under eye area will provide a cushion of volume in the tear trough area. It is important to understand that you are being sculpted. That means you need to go to an artistic injecting physician. Unfortunately, they are not all artists. So that means doing your homework. Restylane is the best product for this and treatment is likely to be effective for more than a year.
A filler can help with the tear trough, but I wouldn't worry about the "sunken eyes" this is a normal variant abd looks good on you. There is no easy way to surgically alter it, and I would caution against attempting to do so
Under eye area dark circle treatment
Dark circles can be present at a young age. Cosmetic treatment may consist of facial filler, such as Restylane to help add volume and reduce appearance of the dark under eye circle. Most plastic surgeons will avoid an eye or tear trough implant. Instead, office filler injection can provide adequate improvement. Fat injections are an alternative for some patients. For younger patients like yourself, office treatments are usually adequate. If you haven't already, then speak with a plastic surgeon to help determine appropriate options for you.
