The under-eye area is one of the first places where signs of ageing start to show- fine lines, dark circles, and volume loss can leave even the healthiest individuals looking tired or stressed.
As aesthetic practitioners, we often hear patients express frustration over their under-eye appearance, yet they’re hesitant about using traditional dermal fillers in such a delicate area. This is where Sunekos treatment stands out.
Designed to stimulate the skin’s natural regeneration process, Sunekos under eye injections offer a subtle, natural-looking solution without adding excess volume. In this blog, we’ll walk through everything medical professionals need to know about Sunekos- how it works, who it’s suitable for, what results to expect, and why it’s becoming a popular choice for under-eye rejuvenation.
Let’s get started.

Let’s break it down. Sunekos treatment is a type of injectable skin booster that uses a patented formula of hyaluronic acid and amino acids. Unlike traditional fillers, it doesn’t just add volume- it helps the skin repair itself.
It stimulates fibroblasts, which then produce collagen and elastin naturally. This leads to tighter, smoother, more hydrated skin. That’s why it works so well for thin, delicate skin like the under-eye area.
The skin under the eyes is thinner and more fragile than the rest of the face. It’s also an area where bone and fat loss is quite noticeable, even in younger patients.
Add in late nights, stress, or just genetics- and you’ve got:
The problem? Fillers here can sometimes cause puffiness or a Tyndall effect (a bluish tint under the skin). That’s why Sunekos under eye treatment is such a game-changer – it hydrates and restores without adding bulk.
At the heart of Sunekos is a patented formula that combines low molecular weight hyaluronic acid with a unique cluster of six amino acids – glycine, L-proline, L-leucine, L-lysine, L-valine, and L-alanine. Together, this mix stimulates fibroblast activity, which in turn helps rebuild the skin’s extracellular matrix (ECM).
So what does that mean in practical terms?
When we inject Sunekos under eye, we’re encouraging the body to produce new collagen and elastin– the two key components responsible for skin elasticity, structure, and firmness. The process is known as biogenesis, and it leads to gradual, natural improvement in skin quality rather than instant volume or plumping.
Here’s a closer look at what’s happening beneath the skin:
The beauty of Sunekos skin booster lies in this subtle, regenerative action. It doesn’t risk overfilling the tear trough area or causing puffiness—something injectors are often cautious about when treating the under-eye region. Instead, it works with the body’s natural biology to bring about steady and reliable improvements.
This makes Sunekos under eye treatment ideal for younger patients showing early signs of ageing, as well as mature patients with crepey skin and volume loss. The results are typically noticeable after the first session but improve over time as collagen remodelling continues. Most protocols recommend a course of three to four sessions spaced 7 to 10 days apart for optimal results.
Understanding this mechanism is vital for anyone undergoing Sunekos training, as it allows us to explain the science to our patients in a way that builds trust and sets realistic expectations. It also helps us assess who is an ideal candidate and why the treatment works so well for the delicate infraorbital area.
You’ll see the best results with patients who:
It’s also perfect for those who don’t want the risk of puffiness or overfilling.
That said, if the patient has very deep tear troughs or extreme hollowness, Sunekos might not be strong enough alone- but it can still be part of a combined approach.
This is where Sunekos really shines.
Patients often report:
The results build over time. Most protocols suggest 4 sessions, spaced 7–10 days apart. Patients usually start seeing visible changes after the second session.
And unlike some treatments, these results actually get better over the following weeks, thanks to the boost in collagen production.
“Sunekos is designed to support skin quality by combining hyaluronic acid with amino acids, helping to improve hydration, elasticity and overall skin texture. The aim is a refreshed, natural-looking result rather than a change in facial shape or adding volume, which patients are increasingly requesting.”

There are a few reasons why injectors prefer Sunekos skin booster over other products for the under-eye area:
| Feature | Sunekos | Traditional Fillers |
| Adds volume | Not primarily | Yes |
| Boosts collagen | Yes | Not significantly |
| Hydrates skin | Intensely | Somewhat |
| Safe for under-eyes | Very safe | Risk of puffiness |
| Natural-looking results | Always | Depends on product |
One of the reasons Sunekos treatment is gaining popularity among both patients and injectors is because the procedure itself is relatively simple, quick, and minimally invasive. But as with any injectable treatment, precision and understanding of the technique are key- especially when working around the delicate under-eye area.
Here’s what a typical Sunekos under eye procedure involves:
a. Consultation and Assessment
Before starting, a full consultation is essential. We assess the patient’s skin condition, degree of volume loss, presence of dark circles or puffiness, and overall facial anatomy. Not everyone is suitable for this treatment- for example, patients with severe fat pad prolapse or excessive laxity may require alternative solutions. But for mild to moderate volume loss and skin crepiness, Sunekos can work beautifully.
b. Skin Preparation
The treatment area is cleansed thoroughly, and a topical numbing cream may be applied to reduce any discomfort. Since Sunekos involves small injections, patient comfort is generally manageable without the need for strong anaesthesia.
c. Injection Technique
Using a fine needle or a cannula (depending on the practitioner’s preference and the patient’s anatomy), Sunekos is injected into the dermis or just beneath it. Multiple small injection points are placed strategically in the under-eye region, usually following the tear trough and extending into the malar area if needed.
It’s important to inject slowly and precisely, as this minimises trauma and ensures even distribution. Because Sunekos is not a filler, we’re not looking to lift or volumise, but to stimulate regeneration from within.
d. Duration and Aftercare
The entire procedure usually takes 20 to 30 minutes, making it easy to fit into a typical clinic schedule. Post-treatment, patients may experience minor swelling, redness, or bruising at the injection sites, but this tends to settle within a day or two. We advise patients to avoid touching or massaging the area, stay away from intense heat (like saunas), and skip strenuous exercise for 24–48 hours.
e. Treatment Plan
Sunekos is typically performed as a course of three or four sessions, spaced about 7 to 10 days apart. This staged approach allows the skin to respond gradually, with results continuing to improve over several weeks.
Results from Sunekos under eye treatments usually last around 6 months, sometimes longer depending on the patient’s skin condition and lifestyle.
A top-up session every 6–8 months keeps the effects looking fresh and consistent.
As with any injectable, there’s always a risk of:
But because Sunekos is so lightweight and bio-compatible, serious reactions are extremely rare. And since it doesn’t add bulk, you don’t get that overfilled look.
Still, proper injection technique is crucial—especially around the eyes.
Here’s why aesthetic practitioners are getting Sunekos training and offering this treatment more and more:
Plus, once clients try it for their under-eyes, they often request Sunekos for the neck, décolletage, or hands too. It’s a great treatment to build patient loyalty.
If you’re thinking about adding this to your aesthetic services, proper training is key. During Sunekos training, you’ll learn:
You’ll also get to practise on live models—which helps you build confidence and real-world skills.
Q: Can you combine Sunekos with Botox or fillers?
Yes, you can! Just space them out properly and always assess skin condition first.
Q: Is Sunekos suitable for older patients?
Definitely. In fact, mature skin responds very well to collagen stimulation.
Q: How soon will my patients see results?
Some improvement is visible after the first session, but the best results show after all 4 treatments.
Q: Is there any downtime?
Most patients experience minimal downtime—maybe a bit of swelling or redness, but it usually settles within hours.
Q: Is Sunekos better than PRP?
They’re different. PRP uses the patient’s own plasma. Sunekos is more targeted for skin hydration and elasticity, especially under the eyes.
