Panda Eye Injections 101: What Are They? Hyaluronic Acid vs Collagen – 5 Key Risks You Should Know

In today’s fast-paced world, late nights are the norm, and even young people often develop prominent “panda eyes.” These stubborn dark circles make you look tired and dull no matter how much sleep you get. If luxury eye creams haven’t helped, it might be time to consider Panda Eye Injections (also known as dark circle injections or collagen injections), which can target the root cause of dark circles. In this blog, we’ll explore the types and causes of dark circles, explain how Panda Eye Injections work, what to watch out for, and possible side effects. We'll also introduce a medical aesthetic treatment that can simultaneously address eye bags, tear troughs, wrinkles, and dark circles.

Types and Causes of Dark Circles

1. Pigmented Dark Circles

These appear brown or black due to melanin buildup and are often caused by excessive sun exposure, frequent rubbing of the eyes, poor makeup removal, overuse of digital screens, or certain medical conditions like autoimmune diseases or dermatitis. When the skin around your eyes is exposed to UV rays or friction, the body produces melanin as a defense mechanism, which then settles under the eyes. Although better blood circulation can slightly fade this type of dark circle, the problem will return if you don’t use sunscreen, continue rubbing your eyes, skip proper makeup removal, or leave medical conditions untreated.

2. Vascular Dark Circles

These are bluish-purple or greyish due to visible blood vessels under the skin caused by vessel dilation, broken capillaries, or poor circulation. Pressing on the area may lighten the color temporarily. Common triggers include lack of sleep, menstruation, crying, eye puffiness, eye strain, excessive salt intake, or allergies. Allergic rhinitis-related dark circles are also vascular in nature. They occur due to congestion and stagnation of blood around the eyes. If allergies are the culprit, you'll need to address the root problem and avoid allergens and irritating skincare products before your dark circles can improve.

3. Structural Dark Circles

Also called pseudo-dark circles, these aren’t caused by pigmentation but rather by shadows created by the facial structure—sunken tear troughs, puffy eye bags, or enlarged fat pads. Causes include genetics or aging-related changes such as skin laxity, collagen loss, soft tissue atrophy, or bone density reduction. These changes create hollowing or bulging under the eyes, leading to shadowing that mimics dark circles. Treating structural dark circles requires addressing the tear troughs and eye bags, often with hyaluronic acid or collagen fillers, or surgical options like fat removal or skin tightening.

4. Mixed Dark Circles

Most people don’t have just one type of dark circle—they often experience a combination, especially pigmented and vascular. Mixed dark circles may appear dark brown with purplish tones. They can result from allergies, frequent eye rubbing, and naturally sunken eye sockets. Lifestyle also plays a big role—irregular sleep, frequent late nights, heavy-flavored diets, and prolonged screen time all lead to puffiness and worsen the condition. Treating mixed dark circles requires a combination approach and more consistent effort.

Types of Panda Eye Injections

1. Hyaluronic Acid-Based Injections

These include popular brands like Teosyal Redensity II from Switzerland and Hearty from China. They contain not just hyaluronic acid but also amino acids, antioxidants, minerals, vitamins, and a mild anesthetic to minimize pain during the procedure. Hyaluronic acid comes in large and small molecular sizes—larger molecules stay on the surface to mask dark circles, while smaller ones are absorbed to plump up sunken areas and firm up sagging skin. This type of Panda Eye Injection is ideal for structural dark circles, as it fills in hollow areas and helps reduce shadowing. It also hydrates and tightens the skin, helping to fade fine lines around the eyes.

2. Collagen-Based Injections

Collagen is naturally present in the body and helps support sunken skin, functioning similarly to hyaluronic acid. A representative product is Sunmax Facial Gain from Taiwan’s Sunmax Biotech, which contains collagen, a phosphate buffer, and lidocaine for pain relief. Collagen injections are biodegradable and naturally absorbed by the body. Their pale white color helps mask pigmentation without causing the “Tyndall effect” (a bluish tint sometimes seen with hyaluronic acid). Since collagen doesn’t draw water like hyaluronic acid, there’s less risk of post-treatment puffiness.

Benefits of Collagen Panda Eye Injections

1. Reduce the appearance of dark circles

Originally developed to treat dark circles, Panda Eye Injections specifically improve the look of pigmented and structural dark circles.

2. Enhance skin elasticity

Collagen and hyaluronic acid strengthen the elastic fiber network in the under-eye area, firming up sagging skin and minimizing shadowing caused by volume loss.

3. Improve overall eye contour

In addition to targeting dark circles, Panda Eye Injections can also reduce tear troughs and fine lines, tightening the skin for a younger, smoother appearance. Because of this rejuvenating effect, they’re sometimes referred to as "youth injections."

4. Minimally invasive

The injections leave only tiny pinprick marks that heal quickly without noticeable scarring. There's no skin damage or surgery involved.

5 Risks and Side Effects You Should Know

1. Limited longevity

Hyaluronic acid injections typically last 4–6 months, while collagen-based ones last 3–4 months. Duration depends on the injection site, dosage, individual metabolism, and lifestyle. Since the effects fade over time, regular touch-ups are necessary to maintain results.

2. Requires high precision

Success depends heavily on the injector’s technique and dosage control. Poor technique can lead to unnatural results like bumps, uneven texture, or small cysts. Too much hyaluronic acid may cause puffiness or the appearance of “tear trough worms,” requiring corrective procedures.

3. Risk of allergic reaction

Some people may react to collagen, hyaluronic acid, or other ingredients in the injection, resulting in rashes, itching, or swelling—potentially impacting appearance and self-confidence.

4. Bruising or infection

Localized bruising or hematomas may occur during the procedure. If the injection tools are not properly sterilized, there's a risk of bacterial infection at the injection site.

5. Skin discoloration

Although the goal is to reduce pigmentation, Panda Eye Injections may sometimes cause unexpected color changes—either deepening the pigmentation or making the area much lighter than the surrounding skin.

7 Key Tips for Getting Collagen Panda Eye Injections

1. Start with a Consultation

First and foremost, visit a few reputable clinics or medical beauty centers for a consultation. Compare their advice and let a professional assess your eye condition, type of dark circles, and overall health (including allergy or medical history) to recommend the most suitable treatment plan.

2. Understand the Procedure and How It Works

Before the injection, make sure you fully understand the steps involved, the underlying principles, potential side effects, and how to handle any complications that may arise.

3. Prepare Ahead

If you’re taking medications such as aspirin or blood thinners, your doctor may advise you to pause them to avoid adverse interactions with the injection ingredients. You should also cut back on smoking and alcohol, avoid excessive sun exposure, and reduce eye strain to lower the risk of bruising.

4. Avoid Touching or Rubbing the Treated Area

After receiving the Panda Eye Injection, avoid touching or rubbing the eye area—even with towels or cotton pads—as this can cause uneven distribution of the hyaluronic acid or collagen, leading to lumps or unevenness under the eyes.

5. Protect the Eye Area from Irritation

For a few days post-injection, avoid sunbathing, hot springs, saunas, and washing your face with hot water. These can trigger swelling or even fungal infections. Also, steer clear of harsh makeup or skincare products near the eyes.

6. Reduce Swelling

You may experience mild swelling, bruising, or discomfort after the procedure. Follow your doctor’s advice and apply a cold compress to help reduce swelling and ease any discomfort. Also, avoid salty and greasy foods, and don’t drink too much water before bed to prevent puffiness. Getting enough rest during this period will help speed up recovery.

7. Follow Medical Advice and Monitor Recovery

If you feel any pain, your doctor may recommend a mild painkiller. Ask your doctor when it's safe to resume wearing contact lenses or applying makeup. While minor redness and swelling are common in the first few days, severe pain or inflammation should be reported immediately.

Hyaluronic Acid or Collagen Panda Eye Injection – Which One Is Right for You?

The first step is to identify your type of dark circles. If you have vascular dark circles, neither hyaluronic acid nor collagen injections are likely to be effective. For pigmented or structural dark circles, it depends on your individual needs.

Hyaluronic acid lasts longer than collagen but tends to retain water, which may cause puffiness. It can also leave a bluish tint at the injection site, potentially making dark circles appear worse.

Collagen injections don’t last as long, but they don’t cause puffiness or discoloration. They also help stop minor bleeding and repair damaged tissue around the eyes, reducing the risk of bruising. However, collagen-based Panda Eye Injections are usually more expensive. If you’re unsure, consult your doctor for a personalized recommendation based on your eye condition.
