Open, Non-comparative Study to Evaluate the Effectiveness and Safety of the Medical Device KOS® L in Correcting Moderate or Severe Nasolabial Folds
Romania34 participantsStarted 2025-06-16
Plain-language summary
The utilization of minimally invasive techniques has brought about a transformative shift in the approach to face rejuvenation, potentially representing one of the most notable advancements in facial plastic surgery in recent times. Originally employed to address the presence of fine lines and wrinkles, the application of fillers has now evolved to encompass the remediation of volume depletion and the enhancement of the aging visage.
KOS® L in the dermis regulates water balance, osmotic pressure and ion flow and functions as a sieve, excluding certain molecules, enhancing the extracellular domain of cell surfaces and stabilizes skin structures by electrostatic interactions.
The Research Question of the present study is the following: to collect sufficient clinical data to demonstrate compliance with the General Safety and Performance Requirements of KOS® L when used as intended.

Exclusion criteria
. Subject having received at any time injection with a slowly resorbable filling product (polylactic acid, calcium hydroxyapatite, combinations of hyaluronic acid (HA) and hypromellose, HA and dextran microbeads or HA and TriCalcium Phosphate (TCP), …) or with a non-resorbable permanent filling product (polyacrylamide, silicone, combination of methacrylic polymers and collagen, polymer particles, …)
. Subject who received oral surgery (e.g. tooth extraction, orthodontia or implantation) within 6 weeks prior to screening visit or who plans to undergo any of these procedures during the study
. Severe midface volume loss or severity of wrinkles or folds requiring other treatments
. Previous tissue revitalization with neurotoxin, laser or light, mesotherapy, chemical peeling, or dermabrasion below the zygomatic arch within 6 months
. Previous tissue augmenting therapy or, contouring, or fat injection in the facial area
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
