The Effects of Hyaluronic Acid on Skin Health

As people age, skin health gradually changes. The structure and function of the skin are modified, its ability to regenerate decreases, and certain biological changes may accumulate over time. These processes can make the skin more fragile and more sensitive to certain diseases, including skin cancer. In dermatological and aesthetic practice, injectable formulations based on hyaluronic acid are widely used to improve skin quality. Although these products are generally well tolerated, their deeper biological effects are most often assessed through subjective clinical observations. Quantitative scientific data are therefore needed to better understand how these products affect the skin. The aim of this study is to determine whether a hyaluronic acid-based formulation induces measurable changes in biological markers associated with skin health and fibroblast activity, which are important for skin regeneration. The study also examines whether these biological changes are accompanied by internal changes in skin structure. For each participant, three skin areas located on the lower abdomen will be studied. One area will receive an injection of the medical device, a second area will undergo needle insertion without injection, and a third area will receive no intervention. The assignment of the interventions to the skin areas will be done by chance, similar to a coin toss. The participant will know which interventions are performed and on which areas, while the evaluators will not. The study includes three visits over a period of approximately six weeks. Non-invasive examinations as well as three small skin biopsies will be performed. There is no direct benefit expected for participants. The risks are mainly local and temporary. The overall results of the study will be shared after its completion in the form of a summary written in language understandable to the general public.
