Lighting and stretch test
The doctor examines the area in different light and gently stretches the skin to classify dark circles.
A tired look under the eyes can come from a tear trough, hollowing, thin skin or one of three kinds of dark circle. Working out which one you have is the key to choosing a gentle, suitable treatment.

Under-eye aging is treated according to its cause. Thin, crepey skin and fine lines often respond to gentle skin boosters such as Rejuran or regenerative care. Dark circles from pigment, visible veins or shadowing each need a different plan, and some shadows are structural. A doctor examines the area in good light before suggesting options.
A tired under-eye usually reflects one or more of three changes: a deepening tear trough, general hollowing, or thinning skin. The tear trough is the groove running from the inner corner of the eye down toward the cheek; it deepens as fat and bone support change with age. Hollowing is a wider loss of volume below the eye. Thin skin lets underlying muscle and vessels show through and creases easily.
A defined groove at the inner lower eye that casts a shadow, sometimes present from youth.
A broader sunken look, often with the cheek appearing flatter below it.
Fine crinkles and a slightly translucent look, worse when smiling or tired.
Dark circles fall into three main types, pigment, vascular and shadow, and many people have a mix. A simple stretch test and good lighting help the doctor tell them apart.
| Type | Colour | Quick check | Typical approach |
|---|---|---|---|
| Pigment | Brown | Colour stays when skin is gently stretched | Skin-tone care, strict sun protection |
| Vascular | Blue or purple | Colour may fade briefly with light pressure | Skin-thickening support, sleep and allergy care |
| Shadow | Grey, changes with light | Improves when you look up into light | Address hollows or structure |
For thin under-eye skin, the gentlest effective options aim to improve skin quality rather than add bulk. At Gangnam Celliting Clinic, options listed for the eye area include Rejuran, eye rejuvenation lifting, wrinkle Botox for expression lines and regenerative treatments. Your doctor may combine a skin booster with a regenerative step for suitable patients.

Under-eye bruising and swelling usually peak in the first one to two days and fade over about a week, though everyone heals differently. A general timeline after injectable skin treatments:
Suitability is a medical decision made by your doctor after an in-person consultation and review of your health history.
The doctor examines the area in different light and gently stretches the skin to classify dark circles.
You hear whether hollowing, thin skin or pigment is the main issue, and what treatment can realistically change.
Numbing is applied; fine injections are placed slowly to limit bruising.
Cold compresses are applied and you receive written aftercare in your language.
Share photos during the free 3-month follow-up after you return home.
Written aftercare in your language, a 24-hour line and a free 3-month follow-up.
No serious complication since 2007. FDA/KFDA-cleared devices and verifiable, genuine consumables.
Monitored sleep sedation, AirNox analgesia, the X-injector or local anesthesia, matched to the procedure.
Allow at least four or five days between an under-eye injection and your flight home if possible, so swelling settles before cabin pressure and long sitting. Book early in your stay in Gangnam, Seoul, and avoid alcohol and salty food for the first nights. A 24-hour contact line is available if you have concerns after treatment. Our doctors consult in English, Chinese, Japanese and Vietnamese, so you can describe your dark circles in your own words.

Usually not completely. Treatment can often lighten or soften dark circles, but results depend on the type. Pigment, vascular and shadow circles each respond differently, and genetics play a part. Your doctor will explain what improvement is realistic for your type before treatment.
Because the skin is very thin and the area has many small blood vessels. Even careful injections can cause a small bruise. Slow technique, cold compresses and stopping certain supplements beforehand, if your doctor agrees, can help reduce the chance.
No. The tear trough is a groove that can cast a shadow, which looks like a dark circle. True dark circles can also come from pigment or visible veins. Many people have both, so the doctor checks the structure and the skin colour separately.
They can be used under the eyes for suitable patients when placed carefully by an experienced doctor. Small bumps, swelling and bruising are the most common reactions. Your doctor will decide whether your skin and medical history make a booster appropriate.
Yes, they support any treatment. Daily sunscreen, enough sleep, treating allergies, not rubbing the eyes and limiting salt and alcohol can all reduce puffiness and darkness. These habits also help results from treatment last better.
