What does research say about VERISOL®?
There’s more to your daily stick than an ingredient list.
From wrinkle volume to nail growth: discover what was measured, who took part and how long it took. The key findings, clearly explained.
Explore the research on the ingredient VERISOL®. Each study explains what was investigated and what the findings mean.
First, what exactly is VERISOL®?
A specific collagen ingredient with a body of research behind it.
Collagen peptides are small protein fragments. VERISOL® is GELITA’s brand name for a specific peptide profile. When exploring the research, it helps to look at the ingredient used, the dose and the outcome measured.
That’s why we use VERISOL® in our formula: the name on the label connects to published research.
