What is causing my undereye circles and how can I fix them?

Hey guys, so just to clarify I am 16 years old and have had these undereye circles for as long as i remember. They look really bad in some lightings and angles (esp on camera, irl it is still visible but not as horrid) but in some lightings like under direct sunlight they are barely visible. In addition, it shows under my concealer like a lottt. ive tried a peachy toned concealer and tbh it has helped a bunch but its still visible in some lightings. I honestly searched and searched and most sites on google say its something called a tear trough and most ppl say it can only be fixed thru filler which i cant do as of yet. If any of you guys have struggled with this problem and was able to fix it (or at least lessen it) can you tell me what products you reccommend? Ive been using the la roche posay pigmentclar anti dark circle cream for months and it hasnt worked, plus ive tried a caffiene serum from the ordinary and it also didnt really help, if it did then it was very subtle bc i couldnt tell a massive difference. Im so tired of looking like i look like i run off of 2 hrs of sleep every day.
