"I've got dark circles from lack of sleep," people say. But there are at least three kinds of under-eye circle (クマ, kuma — the Japanese word also means "bear"), and their causes and fixes are completely different. Some disappear with sleep, some can only be hidden with concealer, and some are beyond what any cosmetic can do. Japanese beauty counters sort them by colour — blue, brown and black — and that is a useful place to start.
| Type | Colour | How to tell | Cause | What to do |
|---|---|---|---|---|
| Blue (circulation) | Blue to purple | Fades when you gently pull the lower lid down. Darker in the morning, on cold days, after poor sleep | The skin under the eye is the thinnest on the body, about 0.5 mm, and the veins beneath show through. Sluggish blood flow makes them look darker | Sleep, warmth (a hot steamed towel), less eye strain, check for iron deficiency. Orange-toned concealer to cancel the colour |
| Brown (pigmentation) | Brown to yellow-brown | Colour does not change when you pull the skin. Does not change when you look up either | Friction (rubbing the eyes, rough cleansing, eye make-up left behind), UV, rubbing from atopic dermatitis or hay fever | Stop rubbing (most important), press eye make-up off with a dedicated remover, sunscreen, keep using a brightening (bihaku) active ingredient (quasi-drug, a Japanese category between cosmetics and medicines). Improvement takes months |
| Black (shadow) | Black to grey | Fades when you look up, or when you raise your face to the mirror. Fades in bright light | Sagging, a bulge of fat (orbital fat) or a hollow under the eye casts a shadow. Age, heredity | Cosmetics cannot address this in principle. Highlighter make-up to lift the shadow, cosmetic medicine (hyaluronic acid filler, fat procedures) |
[Verify] The thickness of the under-eye skin (about 0.5 mm) is a standard figure from dermatology. Check the permitted scope of brightening (bihaku) active-ingredient claims against the Ministry of Health, Labour and Welfare quasi-drug approval records.
Only blue circles darken with lack of sleep. Brown circles are friction and UV, black circles are shadow, and sleep changes neither.
No cosmetic is permitted the claim "makes dark circles disappear". Moisture and less friction help prevent brown circles, but black circles are out of reach in principle.
It can ease blue circles for a while, but the friction creates brown ones. Warming the area without pressing is safer.
Pigmentation takes months to improve, and if you are still rubbing, it comes back. Stop the friction first.
Thick layers settle into fine lines and emphasise the shadow. A thin layer of the right colour for your type, plus light, looks more natural.
