under eye skin advice please

Hoping for some advice / help.

The last year or so I’ve noticed my under eye skin texture has changed a lot. I now have these long li es that almost droop into a C shape under both my eyes. I have no idea what’s caused these. I know it’s only certain lighting where these are noticeable, when I look directly forward in daylight my skin looks normal and clear, but when I’m indoors / certain lighting they are really obvious. I’ve added photos to show the differences.

I’m only 25 and I’m really fixating on this each day, it’s causing me some insecurity and I know I’ve asked people if they can see them irl and they say slightly but there not even bad… but for me as a girl, when I notice something I don’t like, I can’t unsee it.

Context: I did get a smidge of tear trough filler last year and honestly, I think it made my over eyes look worse, almost lumpy. So I got this dissolved about 5 months ago. Anyway I feel like I’m back to square one if not worse

Any advice would be greatly appreciated, ideally I’d rather avoid injectables again because I’m scared lol but if I have to, I certainly will

TIA x
