In short

Sunekos combines hyaluronic acid with amino acids to give the skin the raw materials to rebuild its own matrix, used where skin has thinned, as a course of four sessions one to two weeks apart.

Sunekos combines hyaluronic acid with a patented blend of amino acids intended to support the skin's extracellular matrix — the structural scaffolding that holds skin firm. It is used where skin has thinned and lost density, and it is particularly well regarded around the eyes.

How it differs

Where a skin booster largely hydrates and a polynucleotide supports repair, Sunekos is formulated to give the skin the raw materials to rebuild its own matrix. In practice the three overlap, and which one I recommend depends on your skin rather than on a fixed protocol.

Every treatment begins with a full-face assessment and an honest conversation. If I do not think a treatment is clinically indicated or right for you, I will say so and explain why — including when the answer is to do nothing.

Two panels: one droplet for hyaluronic acid, and another droplet surrounded by six small circles for hyaluronic acid with amino acids. The circles are symbolic ingredients, not molecules drawn to scale.

A closer look

One ingredient category, different formulations

  1. Hyaluronic acid

    Both categories discussed in this guide contain hyaluronic acid.

  2. Amino acids

    Sunekos also contains an amino-acid blend. The ingredients and formulation distinguish the products.

  3. A clinical choice

    Ingredients alone do not tell you which option is appropriate for your skin.

A formulation comparison, not a promise of a biological effect or a treatment result.

Course and results

A course of four sessions, spaced seven to ten days apart, is typical. Results continue developing after the course completes.

You will be given written aftercare before you leave, and a direct number to reach me on if anything concerns you afterwards. Reviews are offered at two weeks so we can assess the result together and adjust if needed.

What the whole course involves, start to finish

This is a course rather than an appointment, and the gaps between sessions are part of how it works.
StageWhat happensWhen
AssessmentYour skin is assessed for what it actually lacks — hydration, density, or repair capacity. These need different productsBefore the first session
Session 1A series of small injections at fixed points, around 20 minutesDay 0
Straight afterwardsSmall raised bumps at each point, settling within hours to a day. Little else to see0–24 hours
The gapNothing visible. This is the phase people mistake for the treatment not working2–4 weeks
The rest of the courseSessions 2 and 3, sometimes 4, at the interval that product calls forWeeks 2–12
The resultFirmness, hydration and texture — judged here, not before8–12 weeks after the final session
MaintenanceA single top-up session rather than a repeat course6–9 months

How the plan is decided

What your skin is short of decides the product

The question at assessment is not which brand you have heard of. It is whether your skin is dehydrated, whether it has genuinely thinned and lost density, or whether its repair machinery needs supporting — because those three want different things, and a product chosen for the first will underperform on the third.

Skin that is reasonably thick but dull and flat generally does well with hydration and firmness. Skin that is crepey and fragile, showing fine lines at rest, usually needs building blocks or a repair signal instead.

Why a course, and why the spacing is not padding

One session produces a signal; a course produces a sustained one, and sustained signalling is what actually changes tissue. The intervals are set by how long the previous session keeps working — treating again before that has finished spends a session on skin that was already busy.

What this category cannot do

None of it changes the shape of your face. If what bothers you is lost volume, a flat midface or a heavy jowl, the honest answer is that you are looking at the wrong category — and a clinic offering a skin treatment for a structural problem is selling rather than assessing.

Common questions

Sunekos — what people ask

Sunekos or polynucleotides — which is better?
Neither is universally better; they suit different skin. Sunekos is formulated around rebuilding the extracellular matrix, polynucleotides around supporting repair. I assess your skin and recommend the one that fits, and sometimes the answer is a combination.
Is it good for under the eyes?
It is one of the areas it is most used for. As with any under-eye treatment, correct assessment of what is actually causing the appearance matters more than the product chosen.
Is Sunekos safe?
The risks are mostly the ordinary ones of any injection — bruising, swelling, small bumps at the injection points, and rarely infection. The products are highly purified and the reaction rate is low. Under the eyes is the area with the most bruising and the least margin for error, which is a reason to ask how often your practitioner treats it.
Can I have Sunekos while pregnant or breastfeeding?
No. Injectable treatment is not offered during pregnancy or breastfeeding, on the same precautionary basis as everything else injectable here.
