Check out here what are the main causes for those dark circles under your eyes
Staying hydrated is vital for more than one reason. Water makes up about 60% of the human body, if you aren’t hydrated enough your body’s tissues will start to shrink, including your skin and the delicate tissue under the eyes. Watch out because caffeine, alcohol, and other diuretics can lead to dehydration and require even more water to recover from.
2-You need to get better sleep
Another fairly well-known cause of dark under-eye circles is not getting enough sleep. This can happen to everyone that is not sleeping as many hours as they need.
It always helps to sleep at the same time every evening so that your body's own circadian rhythm can get used to a regular schedule and prevent insomnia.
3-Stop straining your eyes
When you strain your eyes you are not only hurting your vision but this can also have an impact on your under-eye appearance, too. “When you struggle to see something and strain your eyes, your blood vessels enlarge under your skin and show through as dark circles more prominently,” explains Courtney Rubin, MD, board-certified dermatologist and co-founder of Fig 1 beauty.
4- Seasonal allergies
It is so familiar for dermatologists to see patients with dark circles under their eyes because of seasonal allergies that there’s a name for it: allergic shiners. “Basically, the inflammation from allergic conjunctivitis (allergies affecting the eyes), along with frequent friction and rubbing of an itchy eye area, can lead to broken blood vessels and bruising,” Rubin explains. “As the bruising heals, pigmented hemosiderin (a component of hemoglobin) is left behind, which causes dark marks under the eyes.”
5-Underlying medical condition
Among the most prevalent and unfortunately the most difficult to treat is simply genetics (this is called periorbital hyperpigmentation). You may want to talk to a professional dermatologist to see which cream would work to help you out.
