My dark circles are getting worse. How do you manage them?

I'm really worried because the area under my eyes looks dull and dark. It's really stressful because I hear so often that I look tired. Even when I try to cover it up with concealer, the dullness comes back quickly after a while, so it feels like applying makeup is pointless.

I tried going to bed early hoping getting a good night's sleep would help, and I even looked up a famous eye cream and applied it consistently, but the effect is minimal compared to what I expected... I'm just at a loss as to whether this is simply due to fatigue, if the blood vessels are showing because the skin under my eyes is thin, or if it's hyperpigmentation...

I heard that taking vitamins or massaging the eye area helps, so I tried following those advice, but I was actually worried that it might just irritate my sensitive skin and cause wrinkles. Let's work hard together to take care of our beautiful eyes.
