Investigating how age affects skin responses to hyaluronic acid filler

Investigating Age Dependence of Fibroblast and Extracellular Matrix Responses to Cross-linked Hyaluronic Acid Filler in Human Skin

Not applicable Interventional University of Michigan · NCT06195605

This study is testing how age affects the skin's reaction to a popular filler treatment in people aged 30 to 50 to see which age group benefits the most.

What this trial studies

This study examines the effects of injecting a dermal filler, specifically Restylane-L, on the quality of the skin's extracellular matrix in individuals aged 30 to 50. Participants will receive either the dermal filler or a saline vehicle, allowing researchers to compare the outcomes. The study aims to understand how age influences skin response to this treatment, which could provide insights into optimal cosmetic interventions for different age groups.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy individuals aged 30 to 50 who are seeking cosmetic improvement for photoaging.

Not a fit: Patients who are pregnant, have bleeding disorders, or active skin infections will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the effectiveness of dermal fillers in improving skin quality for patients experiencing photoaging.

How similar studies have performed: While there have been studies on dermal fillers, this specific investigation into age dependence and extracellular matrix responses is relatively novel.
