Tired, dark or hollow-looking under-eyes are one of the most common things people ask us about. Unfortunately the under-eye area can look tired for several different reasons, and the right treatment depends entirely on the cause. A filler that smooths a hollow will do nothing for brown pigment, and no cream will lift a true under-eye bag. In this article, we’ll review what causes dark circles and under-eye hollows, and the treatments that genuinely help.
Please note, we are an online skin clinic so we do not offer dermal fillers or surgery. We have written this because we believe people deserve clear, honest information about all of their options.
What Causes Dark Circles and Under-Eye Hollows?
The under-eye area is delicate, and the skin here is the thinnest on the face. Dark circles and under-eye shadows can come from several different causes, often more than one at the same time. The main ones are:
- Volume loss and hollows: With age the cheek fat descends and the bone around the eye recedes. This deepens the natural groove known as the tear trough, creating a hollow that casts a shadow. The area then looks dark even when the skin itself is fine.
- Hyperpigmentation: Sometimes the darkness is genuine brown pigment in the skin, caused by excess melanin. This is more common in deeper skin tones and gets worse with sun exposure and rubbing.
- Visible blood vessels: Because the skin is so thin, the bluish or purple tone of the vessels underneath can show through. This reads as a dark circle.
- Eye bags: A puffy bulge under the eye is usually fat that has pushed forward, sometimes along with fluid. This is a structural change rather than a colour one.
- Lifestyle: Lack of sleep, dehydration, allergies and rubbing the area all make under-eyes look temporarily darker and more puffy.
Working out which of these is behind your dark circles is the single most important step, because each one responds to a different treatment. Most people have a mix, so a combination often works best.
Tear Trough Filler
Tear trough filler uses hyaluronic acid, a gel-like substance found naturally in the skin. It fills the hollow under the eye and softens the shadow it casts. In the UK, Teosyal Redensity II is the filler licensed specifically for this area, and it contains lidocaine so the treatment is fairly comfortable. Results are visible straight away and usually last around 12 months. If you don’t like the result, or it settles unevenly, hyaluronic acid can be dissolved with an enzyme called hyaluronidase.
The important thing to understand is that filler only treats one cause. It can soften a true hollow beautifully, but it won’t lighten brown pigment and it can’t remove an eye bag. Filler placed into a puffy area can actually make a bag look worse. The under-eye is also one of the highest-risk areas for filler, because the vessels around the eye are easily damaged. Rare but serious problems like vascular occlusion, and very rarely effects on vision, are possible. That is why this should only ever be done by an experienced medical injector.
Skincare for Dark Circles
Where the problem is pigment or skin quality rather than a deep hollow, skincare is the right place to start. It’s also the safest. Retinoids like tretinoin help build collagen and speed up cell turnover, which thickens the thin under-eye skin and fades brown pigment over a few months. Vitamin C and niacinamide brighten the skin and protect against the damage that makes circles worse. For stubborn brown hyperpigmentation, ingredients like azelaic acid and hydroquinone help fade it. Daily sunscreen is essential too, because UV deepens every type of dark circle. Skincare won’t fill a hollow or remove a bag. But for pigmented and crepey under-eyes, it makes a real and lasting difference.
Surgery for Eye Bags
When the issue is a true eye bag, surgery is the only thing that removes it. A procedure called lower eyelid blepharoplasty repositions or removes the fat that creates the bulge, and it can tighten loose skin at the same time. The results are long-lasting. The trade-off is that it’s an operation under local or general anaesthetic, with swelling, bruising and a recovery period, along with the usual surgical risks. It’s worth seeing an oculoplastic surgeon for a proper assessment before going down this route. For many people, skincare and a small amount of filler where appropriate is enough, and surgery is only needed for pronounced bags.
There’s no single best treatment, because it depends entirely on what’s causing your dark circles. If it’s a hollow, tear trough filler is the most direct fix. If it’s brown pigment or thin, crepey skin, skincare is the right and safest place to start. If it’s a true eye bag, only surgery will remove it. And if lifestyle is playing a part, better sleep, hydration and managing any allergies all help. The sensible first step is a detailed honest assessment with a qualified professional. They can tell you which type you have and find best treatment for you.
