Dark Circles Under Eyes / Tear Troughs

No matter how bright, sparkling of eyes you have, having dark circles or tear troughs can unfortunately hide away these eye-catching features and make you look tired. Skincare products rarely treat them from the root. However, aesthetic treatments can get to the bottom  and help you improve them.

What are dark circles and tear troughs

Dark circles under eyes are the pigmentation deposited around the eyes. They are usually caused by tired eyes, lack of sleep, poor blood circulation around the eyes, and genetic factors.

A tear trough is a deep crease extending from the inner corner of eyes to the lower eyelid, or sometimes even to the upper cheek. It is a type of wrinkles that is caused by the sagging soft tissue at the lower eyelids. Tear trough is one of the three types of wrinkles that significantly represent the ageing process.


○ Causes of pigmented and vascular dark circles:

1. As part of the ageing process, our skin loses its fat tissue and collagen, which leads to a thinner skin layer

2. Genetics, inflammation, and extended exposure to the sun can lead to pigmentation;

3. Allergic rhinitis, stuffy nose, and chronic sinusitis lead to poor blood circulation and hyperplasia of microvessels around eyes;

4. Crying too much, overconsumption of salt, menstruation, and edema at the end of pregnancy can result in temporary increase of visible veins;

5. Poor sleep pattern, sleep deprivation, overuse of eyes, stress, and anaemia can cause swallowing and poor circulation around the eyes;

6. Atopic dermatitis, repeated rubbing and scratching, and recurred contact dermatitis can cause skin to be rough;

○ Causes of structural dark circles:

If dark circles are accompanied with severe tear troughs, the dark circles will appear darker and more serious.


● Two types of tear trough: true tear trough and tear trough with bags under eyes

  • True tear trough: characterised by depression or a sunken appearance of the lower eyelid, no under eye bags.
  • tear trough with bags under eyes: characterised by the co-existence of tear trough and bags under eyes.

Because of the light reflection on the skin, the depression at the tear trough often gives the wrong impression of the appearance of bags under eyes.

● Types of dark circles: Pigmented, vascular, and structural

▲Vascular Dark Circle

When the skin around the eyes has thin epidermis and dermis, blood vessels under the skin tend to show through, therefore pink or deep purple may be seen around eyes. Vascular dark circles can be caused by sleep deprivation or staying up late, because when our eyes are tired, the circulation around eyes will become poor and oxygen content in blood become lower, causing the blood to turn dark bluish-red. The resulting dark bluish-red vein will then appear on the skin around the eyes area as greenish, bluish-red.

Find out if you have vascular dark circles quickly: Use your fingers to tap the dark circle, if the colour becomes lighter, it is vascular dark circles.

Pigmented Dark Circles

Pigmented dark circles are often brown in colour, which is caused by the pigment production and accumulation in the skin. Some lifestyles can accelerate the formation of pigmented dark circles such as extended exposure to the sun, poor facial cleansing, and rubbing eyes frequently. Also, pigmented dark circles could be inherited.

Find out if you have pigmented dark circles quickly: Brown skin appears on both upper and lower eyelids.

Structural Dark Circles

Structural dark circles, also known as shadow dark circles, are fake dark circles that are caused by the structural anatomy of the eye socket, skin laxity, bulging bags under eyes, and tear trough. The light reflection on these uneven areas will produce shadows around the eyes area which look like dark circles.

Find out if you have pigmented dark circles quickly: Face to a light source, if the dark circle becomes lighter, it is a structural dark circle.

Dark circles of most people are the combination dark circles type that means a combination of various types of dark circles. It involves multiple considerations when it comes to the treatment of the combination dark circles type. If you are not sure what type of dark circle you have, come to Ai Beauty Clinic for a thorough, professional consultation.

Affected groups

People who stay up late. People who have shown signs of ageing such as dark circles, bags under eyes, wrinkles/lines around their eyes, and tear trough. People who have thin skin at their tear trough area.


As the formation of dark circles and tear troughs are varied and complicated, treatment plans will depend on the person’s actual situation and desired results.

Tear Trough Filler is highly recommended for people who want to restore their brightness and liveliness of their eyes. For all types of dark circles, by simply injecting hyaluronic acid at the dark circles, the skin in the lower eyelids will be pumped and hence reduce the depression at the tear trough, improving the appearance of dark circles. Hyaluronic acid is also a powerful hydration agent that can nourish the skin around eyes, smoothing out wrinkles and lines.

Tear troughs and signs of ageing around the eyes can be treated by the production of collagen. Collagen can quickly give volume at the tear trough, effectively reduce the appearance of tear trough, improve dark circles caused by tear trough, restore drooping skins, and smooth out lines. When the tear troughs are improved, the wrong impression of bags under eyes caused by tear troughs will be improved.
