Sunekos: Hyaluronic Acid Plus Amino Acids, Four Unreported Trials and One Name in PubMed

Sunekos is an Italian injectable of hyaluronic acid and free amino acids sold as a skin booster. Its maker cites a cell study and a small open trial; four registered trials posted no results; PubMed names the brand once. Here is what is in it and what has been measured.

Sunekos is one of the injectables sold to clinics as a "skin booster", with about 900 US searches a month (clickstream estimate, October 2026) for a product that is not approved in the United States. It is a combination of hyaluronic acid and free amino acids. This page sets out what the maker says is in it, where it is registered, and what has been measured, as of 17 October 2026. It does not recommend the treatment; anyone considering an injection should take the evidence below to a licensed clinician.

What is in it

Sunekos is made by Professional Dietetics S.p.A., a Milan company whose aesthetic division, Sunekos Laboratories, says it has specialised in "patented Amino Acids formulas since 1996". The brand site, read on 17 October 2026, lists five injectables — Sunekos 200, 1200, Performa, Body and Cell 15 — and describes them as "a patented combination of hyaluronic acid and amino acids", for use by qualified healthcare professionals only. Sunekos 200 is listed for the face and the area around the eyes, Performa for the face, eyes and neck. The product pages do not list amounts.

The amino acids are named in the published studies of the mixture: glycine, L-proline, L-leucine, L-lysine, L-valine and L-alanine, alongside high-molecular-weight sodium hyaluronate (Kabakci 2024, PMID 38590269). Glycine and proline are the two most common amino acids in collagen, which is the rationale offered: supply the raw materials, and the cells that build collagen may use them.

These are not peptides. A peptide is a chain of amino acids joined by bonds; free amino acids are single units. The distinction matters on this site, where peptides are the subject, and the brand itself does not claim peptides. Where Sunekos sits among the other injectables sold under the same name is mapped on our page about skin boosters.

Where it is registered

Check Result on 17 October 2026

Maker's description of itself "over 90 Class II & III Medical Devices" — European device classes

The product is sold as a medical device in Europe and other markets. It has no US approval or clearance.

What the maker cites

The brand's clinical-studies page lists two papers:

  1. De Servi and colleagues, 2018 (PMID 29921376): mixtures of amino acids and hyaluronic acid applied to cultured human fibroblasts changed the activity of genes for collagen and elastin. The about page says the formula "has been proved by studies" to stimulate fibroblasts to make both. It was a dish experiment; cells in a dish are not skin after an injection.
  2. Sparavigna and Orlandini, 2017, in the Journal of Clinical Trials: a six-month, single-centre, open-label evaluation of an injectable device containing hyaluronic acid and amino acids. Open-label means everyone knew what was injected and there was no comparison group.

The registered trials: four finished, none reported

ClinicalTrials.gov lists four Sunekos trials, all sponsored by Derming SRL and run in Italy:

Trial Product Area People Design Completed Results posted
NCT03274232 Sunekos 200 face, photoageing 25 single arm, unmasked April 2017 no
NCT03425955 Sunekos 200 and 1200 face, two injection techniques 12 non-randomized, unmasked December 2017 no
NCT03881189 Sunekos 200 around the eyes 22 single arm, unmasked March 2019 no
NCT04113265 Sunekos Body inner thighs, knees, arms 24 single arm, unmasked September 2019 no

That is 83 people across four studies, none randomized, none with an untreated or placebo group, and none reported on the registry seven to nine years later. Some may have been published under a generic description rather than the brand name: a PubMed search for "Sunekos" in the title or abstract returned one record on 17 October 2026 — a 2026 study of Sunekos Cell 15 in 46 women with cellulite, without a control group, in which 95.3% reported improvement (PMID 42582402).

The wider literature on hyaluronic acid with amino acids

A broader search for injected hyaluronic acid with amino acids on the face returned 21 records. The most useful is a 2026 meta-analysis of 11 studies (Mosteirin and colleagues, PMID 41724989), which reported lower wrinkle-severity scores and thicker dermis after treatment. Two caveats sit in its own abstract. Most pooled outcomes are before-and-after changes rather than comparisons with a control. And its adverse-event result — a risk ratio of 5.20 with a 95% confidence interval of 0.53 to 50.77, p = 0.16 — is described in the abstract as a "statistically significant difference", which the figures do not support: an interval that spans 1 and a p-value of 0.16 mean no difference was shown either way, and the width of the interval shows how few events there were to count. The authors call for larger prospective studies.

The individual studies are of the same shape: a 37-woman open-label perioral study with 3D photography (Poleva 2022, PMID 36074513), a morphometric study of the mid-face and jawline in women aged 30 to 55 (Kabakci 2024), and similar. None compares the mixture with hyaluronic acid alone in a randomized trial, which is the test of whether the amino acids add anything.

What is not established

Whether the amino acids do anything that hyaluronic acid alone does not; how long any change lasts; how Sunekos compares with PDRN or polynucleotide injections or with exosome treatments; and how often uncommon harms occur. The maker's own trials, if their results were posted, would answer some of this. Until then, the evidence is a cell study, open-label series and a meta-analysis that its own abstract over-reads.

Frequently asked questions

What is Sunekos?

An injectable made in Italy by Professional Dietetics S.p.A. that combines hyaluronic acid with a mix of free amino acids. It is sold to clinics as a skin booster for the face, the area around the eyes and, in some versions, the neck and body. The product line includes Sunekos 200, 1200, Performa, Body and Cell 15.

Does Sunekos contain peptides?

No, as published descriptions read. It contains free amino acids — glycine, proline, leucine, lysine, valine and alanine — which are the units peptides are built from, not peptides themselves. The brand's own pages describe a combination of hyaluronic acid and amino acids and do not claim peptides.

Is Sunekos FDA-approved?

No. On 17 October 2026 FDA's device identification and adverse-event databases held no record for it, and no US premarket approval was found. The brand's parent company describes itself as holding Class II and III medical-device registrations, which refers to European device classes.

Does Sunekos work?

The evidence is small and mostly uncontrolled. The brand cites a laboratory study in cultured cells and a six-month open-label evaluation. Four registered trials of 12 to 25 people finished between 2017 and 2019 without posting results. A 2026 meta-analysis of 11 studies of hyaluronic acid with amino acids reported improvements in wrinkle scores and skin thickness, but most of those studies lacked a control group.

What are the side effects of Sunekos?

The published studies report bruising and other short-lived injection-site reactions, and no serious events. None of the studies was large enough to measure uncommon harms. Hyaluronic acid injections in general carry rare risks of allergic reaction, including a 2025 case report of angioedema after a hyaluronic acid injection, and any injection into the face can enter a blood vessel.

Is Sunekos the same as Profhilo or polynucleotides?

No. Profhilo is hyaluronic acid alone in a stabilised form; polynucleotide and PDRN injections are fragments of DNA; Sunekos adds free amino acids to hyaluronic acid. All three are sold as skin boosters, and none has been compared with another in a published randomized trial.
