Sunekos: The Complete Guide to Skin Regeneration

There's a particular kind of skin concern that fillers can't fix and Botox won't touch. It's not about lines or volume — it's about quality. The skin that looks thin, tired, or somehow less vital than it used to. The texture that's lost its resilience. The under-eyes that look perpetually dehydrated. The neck and décolletage that are starting to betray your age even when your face doesn't.

This is where Sunekos works. And it works differently to almost everything else in aesthetic medicine.

What Is Sunekos?

Sunekos is an injectable treatment built around a patented combination of hyaluronic acid and a specific blend of amino acids — the building blocks your skin uses to produce collagen and elastin. Rather than filling or freezing, it works biologically, prompting your skin to regenerate its own structural proteins from within.

The result isn't a change in shape or volume. It's a genuine improvement in skin quality — the kind that makes people ask if you've had a really good holiday, changed your diet, or finally cracked your skincare routine.

The Science Behind It

Your skin's firmness, elasticity, and hydration depend on two key proteins: collagen and elastin. Collagen provides structural support; elastin allows the skin to spring back into shape. Both decline with age — and once lost, no topical product can fully replace them.

Sunekos targets the Extra Cellular Matrix (ECM) — the scaffolding that supports your skin cells. Its specific amino acid formula (glycine, L-proline, L-hydroxyproline, L-leucine, L-lysine HCL, and L-valine) directly stimulates fibroblasts, the cells responsible for producing collagen and elastin. The hyaluronic acid component simultaneously restores hydration and creates the optimal environment for that regeneration to occur.

The key distinction is that Sunekos doesn't introduce foreign volume — it triggers your skin's own repair mechanisms. The improvement you see is genuinely your skin, restored.

Sunekos vs. Traditional Fillers: Understanding the Difference

This is one of the most common points of confusion — and it's worth being clear about.

Dermal fillers physically add volume beneath the skin. They're excellent for restoring lost structure, lifting hollowed areas, and redefining contours. But they don't improve the quality of the skin itself. A cheek that's been filled with filler is fuller — but the skin sitting over it is unchanged.

Sunekos doesn't add volume. What it does is improve the skin from within — increasing firmness, hydration, and elasticity, and reducing the crepiness, fine lines, and dullness that come with declining collagen levels. The two treatments address different problems, which is also why they work so well together in a comprehensive treatment plan.

What Can Sunekos Treat?

Sunekos is one of the most versatile skin treatments available, and it can be used across a wide range of areas and concerns.

On the face: Fine lines and early wrinkles, loss of skin firmness and elasticity, dehydrated or dull skin, crepey texture around the eyes, forehead, and mouth, and early skin laxity in the cheeks and lower face.

On the neck and décolletage: These are areas that are often neglected but age significantly — and where the skin is too delicate for many treatments. Sunekos is ideally suited to both, improving texture and firmness without risk of over-treatment.

Around the eyes: The periorbital area (around the eyes) is one of Sunekos's most powerful applications. The skin here is the thinnest on the entire face, and it responds poorly to heavy volumising fillers. Sunekos rebuilds the structural quality of this skin without adding bulk — addressing fine lines, dark circles caused by dehydration and thinning, and the loss of elasticity that makes eyes look permanently tired.

On the hands: The backs of the hands are one of the earliest places to show age, and one of the most under-treated. Sunekos can restore hydration, improve texture, and reduce the crepe-like quality that develops as collagen thins.

The Two Formulations: Sunekos 200 and Sunekos 1200

Sunekos comes in two formulations, each suited to different skin concerns and areas.

Sunekos 200 contains a lower concentration of hyaluronic acid and is designed for superficial treatment of fine lines and delicate areas — particularly around the eyes and lips, and for patients with milder concerns or younger skin seeking preventative treatment.

Sunekos 1200 contains a higher concentration and is better suited to areas of more significant skin laxity, deeper lines, and zones requiring greater hydration and structural support — such as the neck, décolletage, and face in older patients.

At Karwal Aesthetics, Dr Karwal will assess your skin and recommend the appropriate formulation — or a combination of both — based on your specific concerns and goals.

The Treatment: What to Expect

Your Consultation

Before any treatment begins, you'll have a thorough consultation with Dr Arun Karwal. This covers your skin concerns, medical history, and what you're hoping to achieve. Sunekos isn't the right treatment for every concern, and the consultation ensures it's genuinely the best option for your skin before any commitment is made.

The Treatment Sessions

A standard course of Sunekos involves three to four sessions, typically spaced 10 to 14 days apart. Each session takes between 15 and 30 minutes. The injections are superficial — placed just beneath the skin's surface using very fine needles — which means discomfort is minimal. Most patients describe it as very manageable, and no significant anaesthesia is required.

What Happens After Each Session

There's no real downtime. You may notice mild redness, small injection marks, or pinpoint bruising immediately after treatment, but these typically resolve within 24 to 48 hours. You can return to normal activities the same day, though we advise avoiding intense exercise, saunas, and alcohol for 24 hours post-treatment.

When Will You See Results?

Results with Sunekos are gradual by design — because they're driven by your skin's own biological processes rather than an instant physical change. Most patients begin to notice improvement after the second or third session, with the full effect becoming apparent in the weeks following the final session as collagen and elastin production continues to develop.

This is one of the reasons results look so natural. The change happens progressively, and the skin simply looks better — not different.

How Long Do Results Last?

Following a full course of treatment, results typically last between six and twelve months. Maintenance sessions every six to nine months are recommended to sustain the improvement and continue supporting collagen production over time.

Who Is Sunekos Best Suited For?

Sunekos is suitable for a wide range of patients, from younger individuals looking to protect and maintain their skin quality to older patients wanting to address more established signs of ageing.

It's particularly well-suited to patients who are noticing early signs of skin ageing — thinning, dehydration, fine lines, and loss of elasticity — but don't yet need or want more volumising treatments. It's also an excellent option for anyone who has had fillers or other treatments and wants to improve the underlying quality of their skin, not just its structure.

Sunekos is not recommended during pregnancy or breastfeeding, for patients with active skin infections or inflammation in the treatment area, or for those with a known hypersensitivity to any of the ingredients. Blood-thinning medications and certain medical conditions should be discussed at consultation.

Why Sunekos at Karwal Aesthetics?

The eye area, neck, and décolletage demand precision. These are zones where technique, product selection, and depth of placement matter enormously — and where an experienced injector makes all the difference between a result that looks genuinely refreshed and one that simply doesn't deliver.

Dr Arun Karwal assesses every patient individually. Sunekos is recommended only where it's genuinely the right fit, and it's frequently combined with complementary treatments — such as skin boosters, Profhilo, or targeted filler — where a more comprehensive approach would deliver better results for your specific skin.

Frequently Asked Questions

Is Sunekos the same as Profhilo? No. Both are injectable skin treatments based on hyaluronic acid, but they work differently. Profhilo focuses primarily on bio-remodelling and deep hydration using a high concentration of HA. Sunekos combines HA with amino acids to specifically stimulate collagen and elastin via ECM regeneration. They address overlapping but distinct concerns, and can work very well together.

Can Sunekos replace tear trough filler? Not exactly. Tear trough filler adds volume to the hollow beneath the eye. Sunekos improves the quality and hydration of the skin in that area. For some patients, Sunekos addresses the concern sufficiently — particularly where the issue is skin thinning and dehydration rather than true hollowing. For others, a combination of both delivers the best result. This is something Dr Karwal will assess at consultation.

How many sessions do I need? A standard course is three to four sessions, spaced 10 to 14 days apart. The exact number depends on your starting point, the area being treated, and the formulation used.

Is it painful? Discomfort is minimal. The needles used are very fine and the injections are superficial. Most patients find it very manageable without the need for topical anaesthetic, though this can be applied if preferred.

Can men have Sunekos? Absolutely. Sunekos is equally effective for men and women, and is an increasingly popular treatment for male patients looking to improve skin quality without the downtime or visibility of more invasive procedures.
