Dark circles make you look tired, older, or unwell — and I understand completely how much they affect your everyday confidence. Many people have tried several brands of cream with no improvement; some get plenty of rest yet still find their under-eye area dark.
What many people don't realize is that dark circles are not the same problem for everyone. There are 4 completely different types, and each one needs a different treatment. Using a cream or a method that doesn't match the type simply won't work, no matter how expensive it is. In this article, Dr. Time will help you understand where your dark circles come from and how to fix them.
Gently stretch the skin under your eye and observe — if the color fades: it's likely a hollow/shadow → filler can help. If the color stays dark: it's likely pigment or blood vessels → laser/PRP can help. If it pales when you press gently: it's likely venous → PRP/Skin Booster.
This test is only a preliminary guide. An accurate diagnosis requires a direct examination by a doctor.
The 4 Types of Dark Circles — Identify Before Treating
Something I see very often is patients asking, "Can I just get under-eye filler?" without yet knowing where their dark circles come from. But if that question is answered wrongly — getting filler when the real problem is pigment — you waste money and get poor results. So I want everyone to first understand that dark circles come in 4 types that must be treated in completely different ways.
Type 1 — Vascular (Blood Vessels Showing Through Thin Skin)
The skin under the eye is just 0.5 mm thin — the thinnest in the body — which lets veins show through easily. If your dark circles are purple or blue and pale when you press gently, that's the sign of this type. It's often clearly visible in people with naturally thin skin, or on days with little sleep because the blood vessels dilate.
Type 2 — Pigmented (Accumulated Melanin)
This is common in Thai and Asian people, because our skin produces pigment more readily. If your dark circles are brown, the color doesn't fade at all when you stretch the skin, and they look darker after sun exposure — that's accumulated pigment. The causes can be genetics, UV sun exposure, or a habit of frequently rubbing the eyes.
Type 3 — Structural (Tear Trough / Volume Loss)
This one is a shadow, not skin color. It's caused by the tear trough and the loss of fat around the eyes with age, creating a depth between the lower eyelid and the cheek. Light falling on that area makes it look dark. An easy way to check is to stretch the skin — the color fades significantly. It usually becomes clearly visible from around age 35 onward.
Type 4 — Mixed
This is the most common in the clinic. Many people have both tear troughs and pigment at the same time, or both blood vessels and volume loss combined. Treatment must be planned across several dimensions at once, which is why a direct assessment by a doctor is so important in these cases.
- 🟣 Purple/Blue = Blood vessels (Vascular)
- 🟤 Brown = Pigment (Pigmented)
- ⬛ Dark/Gray shadow = Tear trough (Structural)
- 🔀 Mixed colors = Mixed type
The Cause and Mechanism of Each Type
Got questions? Dr. Time offers personalized, honest consultations — no upselling.
Consult Dr. TimeWhy the Skin Under the Eyes Is Thinner Than Elsewhere
The skin under the eyes is the thinnest in the body — only 0.5 mm thick, compared with 2 mm on the face — which lets veins show through easily, and the collagen loss that comes with age is most noticeable in this area.
Triggers That Make It Worse
- Sleep deprivation — dilates blood vessels and makes the skin pale, making purple dark circles more visible
- UV / sunlight — stimulates the melanocytes under the eyes, increasing pigment
- Age — collagen and the fat around the eyes decrease, deepening the tear trough
- Genetics — thin skin, deep tear troughs, and a tendency to accumulate pigment can all be inherited
- Rubbing the eyes — breaks capillaries + triggers inflammation → PIH
- Allergies — cause itching and eye-rubbing, with venous congestion from swelling
- Dehydration — the skin looks sunken and the tear trough becomes more pronounced
Under-Eye Filler (Tear Trough Filler)
Hyaluronic Acid filler in the tear trough area is the most effective method for structural-type dark circles, adding volume to the tear trough to reduce the shadow that makes the area look dark.
The HA Filler Used Under the Eyes
You have to choose an HA with low hygroscopicity, because if it absorbs too much water it can swell into a "water bag" that is difficult to fix:
- Restylane (Galderma) — includes Restylane-L and Restylane Eyelight, designed specifically for the under-eye area
- Juvederm Volbella (Allergan) — a low-viscosity HA that absorbs little water, suitable for thin skin
- Both brands are HA, which can be dissolved with the enzyme Hyaluronidase if the result is poor or a complication occurs
Injection Technique — Cannula vs Needle
Most doctors recommend a cannula (blunt-tip) rather than a needle for the under-eye area, because:
- It reduces the risk of accidentally piercing a blood vessel
- Less bruising
- It distributes the HA more evenly
The under-eye area is the riskiest place in the body for filler injection, because the Angular Artery and Infraorbital Artery run through it. If filler is injected into a blood vessel and not corrected in time, it can cause tissue death or, in severe cases, blindness. It must be performed by a doctor with genuine expertise who always keeps Hyaluronidase on hand.
Results and Duration
Results are visible immediately after injection, with bruising and swelling for 3–7 days, and the full result clearly visible after 2 weeks. The result lasts 9–18 months, depending on the HA used and each person's metabolism.
Laser and Pico for Under-Eye Pigment
For pigmented-type dark circles, laser is the most precisely targeted option:
Pico Laser 1064 nm — Recommended for Thai Skin
The 1064 nm Pico Laser works well for under-eye pigment in Asian skin, because the risk of PIH is lower than with the older Q-switched lasers. It must be done with great care because of the proximity to the eye — the doctor will place an Eye Shield to protect the cornea every time.
Q-switched Nd:YAG 1064 nm
Still effective in some people and lower in price than Pico, but carries a higher PIH risk in Fitzpatrick IV+ skin.
Under-eye pigment: most cases require 4–6 sessions, spaced 3–4 weeks apart. Results depend on the depth of the pigment and on sun protection during the course of treatment.
PRP + Skin Booster — For Thin Under-Eye Skin
PRP (Platelet-Rich Plasma)
PRP is collected from the patient's own blood, spun to separate out concentrated platelets (Platelet-Rich Plasma), then injected back into the under-eye skin layer. The growth factors from PRP stimulate collagen production, thickening the skin, reducing translucency, and making the veins harder to see through.
It is best suited to vascular-type dark circles and requires 2–3 sessions, spaced 4 weeks apart.
Skin Booster (Diluted HA)
Heavily diluted HA is injected as micro-droplets beneath the skin, stimulating hydration and collagen, thickening the under-eye skin and making it look "better" overall — for example Restylane Skinbooster and Profhilo. It suits vascular cases with thin, dry skin.
Creams and Skincare That Genuinely Help
Ingredients Backed by Evidence
Not every ingredient sold as "under-eye nourishment" actually helps with dark circles. The ones genuinely supported by research are these:
- Retinoid (Retinol / Tretinoin) — this is the best one for the under-eye area. It stimulates collagen, thickens the skin, reduces the visibility of blood vessels, and also reduces pigment. But it must be used continuously for 3–6 months to see results.
- Vitamin C (L-Ascorbic Acid ≥10%) — reduces pigment and stimulates collagen; must always be used in the morning together with sunscreen.
- Caffeine — temporarily constricts blood vessels and reduces puffiness, helpful on days with little sleep, but it is not a permanent treatment.
- Niacinamide 5%+ — reduces pigment and evens out skin tone; easy to use and rarely irritating.
- Peptides (Palmitoyl Tetrapeptide) — provide a slight collagen benefit, suitable as a complement to the others.
Single-ingredient products rarely work — for example, caffeine alone. And if your dark circles come from a tear trough, no topical cream can possibly help, because the problem is structural, not skin color.
Most dark circles can be fixed — you just have to know which "type" it is first. Choosing the method that matches the type is the difference between a good result and wasted money. Let me assess it for you first, and then we'll decide together.
Comparison: Which Method Suits Which Type of Dark Circle?
| Dark Circle Type | The Targeted Method | Methods That Don't Help | Time to See Results |
|---|---|---|---|
| Vascular (purple/blue) | PRP, Skin Booster, adequate sleep, Retinoid | Filler (off-target), laser | 2–4 months |
| Pigmented (brown) | Pico Laser 1064 nm, Q-switched, Vit C + Retinoid, sun protection | Filler, PRP alone | 3–6 months |
| Structural (tear trough/shadow) | HA filler (tear trough), fat grafting | Creams, laser, PRP alone | Immediately after treatment |
| Mixed | Combined methods based on the main cause | A single method alone | 3–6 months |
| Method | Best For | Result Lasts | Downtime | Price Factors |
|---|---|---|---|---|
| Under-eye filler | Structural / tear trough | 9–18 months | Bruising & swelling 3–7 days | Amount of HA + brand |
| Pico Laser 1064 nm | Pigmented | Long-lasting (with sun protection) | Redness 1–3 days | Number of sessions |
| PRP | Vascular / thin skin | 6–12 months | Slight swelling 1–2 days | Number of sessions |
| Skin Booster | Vascular + dry skin | 6–9 months | Slight swelling 1–2 days | Type of agent + amount |
| Retinoid + Vit C | Pigmented (supplementary) | Requires continuous use | None | Lowest cost |
Pricing and the Factors That Determine It
Factors That Make Prices Differ
- The type of dark circle — structural cases need filler, which is priced differently from laser treatment
- The brand and amount of filler — the under-eye area uses little (0.5–1 ml), but the right brand must be chosen
- The number of laser/PRP sessions — pigment requires several rounds
- Some cases require combining several methods — raising the total price
Quoting a price without first examining the type of dark circle can lead to misunderstanding. Dr. Time will assess the type of your dark circles first, then tell you the price of the method that is genuinely right for you. There is no charge for the consultation.
Safety and What to Watch Out For
The Under-Eye Area — A Place That Requires Special Caution
The area around the eyes is one of the riskiest regions in aesthetic work, both for injections and for lasers, because:
- The Angular Artery and Infraorbital Artery lie close to the injection area
- The skin is very thin, with a greater risk of bruising and side effects
- The eyes must be protected from laser light every time
Complications You Should Know About
- Tyndall Effect — HA placed too superficially makes the under-eye skin look blue; correctable with Hyaluronidase
- Water bag / swelling — HA absorbing too much water; prevented by choosing the right type of HA
- Vascular Occlusion — an emergency that must be treated immediately
Warning Signs to Return to the Doctor Urgently
- The skin in that area becomes pale or changes color abnormally after injection
- Increasing pain or increasing swelling after 48 hours
- Abnormal vision

Frequently Asked Questions
Can lack of sleep cause permanent dark circles?
Sleep deprivation causes temporary dark circles from dilated blood vessels, but chronic, long-term sleep loss thins the skin and reduces collagen production, which may accelerate the worsening of dark circles over the long run. Getting 7–9 hours of sleep per night genuinely helps.
Is under-eye sun protection really important?
It's very important, especially for pigment-type dark circles. UV stimulates the under-eye melanocytes very easily. Use a physical sunscreen (Zinc Oxide), which is gentler and doesn't irritate the eyes.
Can under-eye filler be redone after it wears off?
Yes. Most people re-inject every 12–18 months. Some find that after repeating it several times, the HA stimulates accumulated collagen, making the result last longer over the long term.
Do dark circles in "children" need treatment?
In children and teenagers, dark circles usually come from genetics or allergies, and most do not yet require a procedure. Basic care (enough sleep, sun protection, treating allergies) is usually sufficient. I'll advise according to age and what is appropriate.
