Concealer hides them for a few hours, but dark circles keep coming back. Understanding why they appear is the first step to making them look lighter.
Why do dark circles happen?
The skin under your eyes is the thinnest on your face. As it gets thinner with age, what lies underneath shows through more. Short nights, screens, dehydration, allergies and genetics all make it more visible.
The three common types
Shadowy circles
Caused by hollows or puffiness casting a shadow. Hydration and depuffing help most.
Bluish or purple circles
Visible blood vessels through thin skin. Cooling, good sleep and hydration help them look less noticeable.
Brown circles
Often linked to pigmentation and sun. Daily SPF and brightening skincare matter most.
Habits that help
- Protect your sleep: aim for a dark, cool room and a regular bedtime.
- Drink water and go easy on salt and alcohol in the evening.
- Wear sunglasses and SPF around the eyes.
- Don't rub your eyes; treat the area gently.
Products that help them look lighter
Hydrating under-eye patches give an instant fresher look. A silk sleep mask supports deeper rest. A gentle red light eye massager turns care into a calming daily ritual.
When to see a doctor
If dark circles appear suddenly, affect one eye only, or come with swelling or pain, speak to your GP.
