Carboxytherapy for Dark Circles in Istanbul
Carboxytherapy dark circles Istanbul treatment is one of the most effective non-surgical solutions for under-eye darkness caused by poor circulation and thin skin.
For many people, under-eye darkness isn’t a lifestyle problem — it’s a structural one. No amount of topical product can fix poor circulation or thinning skin beneath the eye. That’s exactly what carboxytherapy is designed to address — and why it’s one of the most requested treatments at BrenewSkin in Maslak.
This guide explains how it works, whether it’s right for your specific type of dark circles, and what results actually look like.

Why Do Dark Circles Form? (And Why Creams Don't Fix Them)
Before choosing a treatment, it helps to understand what you’re actually treating. Dark circles are caused by one or more of these factors — and the cause determines the solution:
- Poor microcirculation: Stagnant blood under the thin eye skin creates a bluish or purple tint visible through the surface. This is the most common cause and the one carboxytherapy directly targets.
- Thin, translucent skin: The under-eye area has some of the thinnest skin on the body. As collagen decreases with age, underlying vessels and shadows become more visible.
- Hyperpigmentation (melanin): Excess melanin deposits — often genetic or triggered by sun exposure — create a brownish discoloration. More common in medium and darker skin tones.
- Volume loss and hollowing: As fat pads under the eye shrink with age, a shadow forms in the tear trough that mimics or deepens the appearance of dark circles.

Does Carboxytherapy for Dark Circles in Istanbul Really Work for Dark Circles?
For vascular dark circles — the bluish-purple type caused by poor circulation and thin under-eye skin — the answer is yes, and it’s well-supported by clinical evidence. A 2023 clinical trial published in PMC evaluated carboxytherapy against microneedling with topical agents for periorbital hyperpigmentation and found significant improvement in both darkness and skin quality with carboxytherapy.
The mechanism is straightforward: CO₂ injection triggers the Bohr effect, causing a rush of oxygenated blood to the treated area. Repeated sessions improve local microcirculation structurally — not just temporarily — and stimulate new collagen production, which thickens the under-eye skin over time.
For brown pigmented circles, results are more modest. For hollow tear trough shadows, carboxytherapy is not the primary solution. The type of darkness matters.
Best results for:
✔ Bluish / purple dark circles
✔ Thin or translucent under-eye skin
If your dark circles are caused by pigmentation or hollowing, results may be more limited — and a combination treatment may be recommended instead.
How Carboxytherapy Treats Dark Circles — Step by Step
carboxytherapy dark circles Istanbul works by stimulating your body’s natural response to carbon dioxide, improving circulation and skin quality over time.
Step 1 — Skin Consultation & Assessment
Identifying Your Dark Circle Type
A doctor assesses the cause of your dark circles — vascular, pigmented, structural, or mixed — and confirms carboxytherapy is appropriate for your skin type. Treatment parameters are set based on your Fitzpatrick skin type and sensitivity level.
Step 2 — Skin Cleansing & Preparation
Treatment Area Preparation
The under-eye area is gently cleansed to remove makeup, oil, and impurities. This helps prepare the skin for a more effective and controlled treatment session.
Step 3 — Controlled CO₂ Application
Medical-Grade Carbon Dioxide Injection
A very fine needle delivers a controlled amount of pharmaceutical-grade CO₂ gas just beneath the skin. Your body detects the CO₂ as a signal of low oxygen and responds by sending a rush of oxygenated blood to the area — this is the Bohr effect. You may feel a brief pressure or mild tingling as the gas disperses.
Step 4 — Skin Response Monitoring
Real-Time Safety Check
During the session, the skin’s response is monitored to ensure safety and maximise the treatment benefit. Flow rate and injection depth are adjusted as needed.
Step 5 — Calming & Skin Hydration
Post-Treatment Aftercare
After the session, soothing and hydrating skincare products may be applied to calm the skin and enhance the rejuvenation results. You can return to normal activities immediately.
Carboxytherapy for Purple vs. Brown Dark Circles
One of the most important distinctions — and one most clinics skip over — is that dark circles look different depending on their cause, and treatment should be matched accordingly.
Purple / Bluish Dark Circles
These are caused by poor circulation and thin under-eye skin, making blood vessels more visible. Carboxytherapy works very effectively for this type by improving blood flow and stimulating collagen production.
- Highly effective — visible improvement within a few sessions
Brown / Pigmented Dark Circles
These are caused by melanin (pigmentation), often due to sun exposure or genetics. Carboxytherapy has a limited effect on pigmentation and is usually not the primary treatment.
- Partial improvement — chemical peel or combination treatment is more effective
The most important factor is identifying your dark circle type correctly. During your consultation, we determine the exact cause and recommend the most effective treatment for your skin.
Is Carboxytherapy Safe Under the Eyes?
Yes — when performed by a trained medical professional using pharmaceutical-grade CO₂, carboxytherapy dark circles Istanbul has an excellent safety record for the periorbital (under-eye) area. CO₂ is completely biocompatible; it’s a gas your body naturally produces and exhales, so there is no risk of allergic reaction.
The under-eye area requires a more careful technique than body applications due to the thin, delicate skin. At BrenewSkin, the treatment is performed by a doctor using specifically calibrated flow rates for the periorbital zone.
Common mild side effects include:
- Mild redness at injection sites — resolves within 2–4 hours
- Temporary puffiness directly under the eye — resolves within 10–30 minutes
- Occasional minor bruising — uncommon, fades within a few days
Who Is NOT a Candidate for Carboxytherapy?
carboxytherapy dark circles Istanbul is not appropriate for everyone. The following are contraindications that will be screened at consultation:
- ✕ Pregnancy or breastfeeding
- ✕ Active skin infection or open wounds at or near the treatment area
- ✕ Severe cardiovascular or respiratory conditions (heart failure, severe asthma, COPD)
- ✕ History of deep vein thrombosis or blood clotting disorders
- ✕ Epilepsy — risk of vasovagal response
- ✕ Recent cosmetic injections (filler/Botox) in the treatment area — a waiting period applies
Is Under-Eye Carboxytherapy Right for You?
Here's an honest breakdown based on dark circle type:
| Type of Dark Circle | Carboxytherapy | Alternative / Combination |
|---|---|---|
| Bluish / purple tint (vascular) | Highly effective | Can add mesoneedling for enhanced results |
| Skin thinning / translucency | Effective over sessions | Meso MD for additional skin quality boost |
| Brown / pigmented (melanin) | Partial benefit | Chemical peel as primary treatment |
| Hollow / tear trough shadow | Not the right treatment | Hyaluronic acid filler or PRP |
| Mixed (vascular + pigmentation) | Addresses vascular component | Combination protocol at consultation |
During your first appointment, a doctor at BrenewSkin will assess your specific type and be direct about what treatment — or combination of treatments — will produce the best outcome for your skin.
How Many Sessions Do You Need?
- Mild darkness: 4–6 sessions, once per week
- Moderate darkness: 6–8 sessions, once per week
- Significant or long-standing circles: 8–10 sessions, possibly combined with mesoneedling or Meso MD
Most patients notice a visible improvement after sessions 3–4. The full effect develops 4–6 weeks after the final session, as collagen continues to remodel beneath the surface.
How Long Do Results Last?
This is one of the most commonly searched questions — and deserves an honest answer.
The improvement from a completed course is long-lasting, but not permanent. carboxytherapy dark circles Istanbul improves the skin’s biology — it stimulates new collagen and improves circulation — but it doesn’t stop the natural aging process. Skin continues to thin over time, and circulation can decrease again without maintenance.
Most patients sustain their results with maintenance sessions every 3–6 months. Without maintenance, the improvement gradually fades over 6–12 months as the underlying causes continue to progress.
Important: Results are cumulative. Patients who complete a full initial course and follow a maintenance schedule typically see much more durable improvement than those who do a few sessions and stop.
Carboxytherapy vs. Other Under-Eye Treatments
vs. Eye creams: No meaningful comparison for vascular circles. Creams hydrate the surface; carboxytherapy dark circles Istanbul changes the tissue beneath.
vs. Mesoneedling: Mesoneedling delivers active serums deep into the skin to boost hydration, radiance and collagen. For dark circles, carboxytherapy is more targeted at the circulatory cause; combining both gives superior results for mixed dark circle types.
vs. Chemical Peel: Chemical peels address pigmentation and surface discoloration — better for brown, melanin-based circles. For vascular or structural circles, carboxytherapy is more appropriate and safer for darker skin tones.
vs. Meso MD: Meso MD uses a personalised serum protocol for overall skin quality improvement. It can be combined with carboxytherapy in the same treatment plan for patients who want to address both circulation and skin condition simultaneously.
vs. Hydrafacial: Hydrafacial improves overall skin tone, hydration, and radiance. It’s excellent for skin health but doesn’t directly target under-eye circulation. Many patients combine a Hydrafacial series with carboxytherapy sessions for a comprehensive approach.

Is This Treatment Right for You? A Quick Summary
If your dark circles are primarily bluish or purple — caused by poor circulation or thinning under-eye skin — carboxytherapy is one of the most targeted, evidence-backed non-surgical options available, with no downtime required.
But not all dark circles respond the same way.
If the cause is more likely pigmentation or hollowing, carboxytherapy may still play a role — but often not as the primary treatment. In fact, many people see better results when pigmentation is addressed directly with treatments like chemical peels. If you’re unsure whether this applies to you, it’s worth taking a closer look at how this approach works on our Chemical Peel for Acne Scars in Istanbul page.
If you’re still unsure which type you have, the most effective next step is a personalised consultation at BrenewSkin — where we assess your skin and guide you toward the treatment plan that will deliver the most visible, realistic results.
