You catch your reflection, notice the shadows under your eyes, and wonder if you just look perpetually exhausted. Before you buy another eye cream that promises to erase them overnight, it helps to know this: dark circles are common, usually harmless, and rarely fixed by a single product. The reason one treatment works for your friend but not for you is that dark circles have different causes, and the right fix depends on yours.
Here's how dermatologists actually think about under-eye darkness, and what genuinely helps for each type.
What causes dark circles under the eyes?
Dark circles are technically called periorbital hyperpigmentation, and they happen for more than one reason. According to a comprehensive review in the Journal of Clinical and Aesthetic Dermatology, they fall into four main types, and knowing which you have is what determines which treatment will actually work.
The skin under your eyes is some of the thinnest on your body, so what lies beneath it shows through easily. Mayo Clinic lists the most common causes as allergies, eczema, fatigue, rubbing or scratching the eyes, thinning skin from aging, and an inherited (genetic) tendency. Cleveland Clinic adds that dark circles are more common in older adults, people with a genetic predisposition, and those with darker skin tones.
- Pigmented (brown): extra melanin in the skin, often genetic or from sun exposure
- Vascular (blue, pink, or purple): blood vessels showing through thin skin
- Structural (shadow): hollowing at the tear trough or under-eye fat creating a shadow
- Mixed: a combination of the above, which is very common
Does lack of sleep really cause dark circles?
This is the most common myth, and the answer is nuanced. Mayo Clinic notes that lack of sleep does not usually cause dark circles directly. Instead, being tired makes your skin look paler, which makes any existing darkness more noticeable. So sleep matters, but mostly because it changes how visible your circles are rather than creating them from scratch.
That said, rest still helps. Cleveland Clinic recommends 7 or more hours of sleep, along with an elevated pillow and cold compresses, as sensible first-line measures, especially if puffiness or fluid pooling is part of the picture for you.
How to get rid of dark circles at home
Start with the low-risk basics, because they address several causes at once and cost almost nothing. These won't transform deep structural shadows, but they can meaningfully reduce darkness driven by pigment, puffiness, or visible vessels.
If allergies or eczema are part of your picture, treating those is often the single most effective home step, because the rubbing and inflammation they cause can darken the area over time.
- Wear daily sunscreen around the eyes to limit pigment from sun exposure
- Aim for consistent sleep (7+ hours) and sleep with your head slightly elevated
- Use a cold compress to calm puffiness and shrink visible vessels temporarily
- Stop rubbing and scratching your eyes, and treat underlying allergies or eczema
- Limit alcohol and smoking, and stay hydrated
- Use a color-correcting concealer to cover what skincare can't
What treatments actually work for dark circles?
This is where matching the treatment to the cause matters most. A 2021 systematic review in Dermatologic Surgery analyzed 39 studies and reached a clear, practical conclusion: there is no one-size-fits-all fix, and the best option depends on why your circles are there.
For pigment-based (brown) circles, topical agents and chemical peels help most. Commonly studied ingredients include hydroquinone (2 to 6 percent), kojic acid, azelaic acid, vitamin C, arbutin, and retinoids such as tretinoin or retinol. For the vascular or puffiness component, ingredients like caffeine and niacinamide are often used. Lasers offer mild-to-moderate benefit for both pigment and vascular types.
For structural circles caused by volume loss at the tear trough, the review found soft-tissue fillers and autologous fat grafting to be the most effective options. When loose, sagging skin is the driver, blepharoplasty (eyelid surgery) tends to work best. The review's authors caution that high-quality evidence in this area is limited, so these are general patterns rather than guarantees.
- Pigment (brown): topical depigmenting creams, chemical peels, lasers
- Vascular (blue/purple): caffeine, niacinamide, sometimes laser
- Structural (shadow): fillers or fat grafting; surgery for loose skin
- Mixed: combining a few approaches usually works better than one alone
When should you see a doctor about dark circles?
Most dark circles are a cosmetic concern, not a medical one. But it's worth getting checked if the darkness is sudden, only on one side, painful, swollen, or paired with other symptoms, since these can occasionally point to something other than ordinary pigmentation.
It's also reasonable to see a clinician simply because you want results. Because effective treatment hinges on identifying your specific type, and because some options (prescription-strength topicals, peels, lasers, fillers) require professional oversight, a personalized assessment saves you money and trial-and-error. If you'd rather start with a clinician-guided plan, a service like Nolla can help match a routine to what's actually causing your dark circles.
