Beauty Through Science (BtS) is an annual boutique congress held in Stockholm, Sweden, dedicated to showcasing the year’s most significant science-driven advancements in aesthetic medicine. The BtS 2026 edition focused on the themes of longevity and regeneration. Nordberg Medical presented recent data from its ongoing studies and highlighted its continued efforts to establish a deeper scientific understanding of regeneration and its role in aesthetic medicine.
Defining collagen regeneration
BtS is Northern Europe’s largest congress in aesthetic medicine, with a strong focus on creating close dialogue and knowledge exchange among aesthetic experts. We had physicians from around the world joining us, which reflects the continued growth and strong market position of Nordberg Medical.
Since BtS centers around intimate and in-depth conversations, it provided the perfect opportunity to begin defining what collagen regeneration implies in aesthetics.
Numerous manufacturers assert that their products deliver regenerative outcomes. However, when viewed through the broader lens of regenerative medicine, the definition of regeneration extends far beyond the stimulation of collagen production alone. While collagen synthesis remains an important component of skin rejuvenation, it represents only one aspect of a far more complex biological process.
Regeneration involves supporting the skin’s intrinsic ability to repair, restore, and maintain healthy function over time.1 In this context, regeneration should not only be measured by visible aesthetic improvement, but also by biological changes that contribute to healthier and more functional skin.
Evidence of regeneration
As part of its scientific program at BtS 2026—including symposium sessions, scientific presentations, and demonstrations at the booth—Nordberg Medical presented new data on regeneration. The findings included histological images illustrating the skin’s response to different PLLA-based biostimulators.2
The data demonstrates that significant differences exist between biostimulators, even when they are based on the same biomaterial (PLLA).2,3 At the same time, we showed that flake-like shaped PLLA products can trigger prolonged inflammatory responses and impair the skin’s regenerative pathways.2
Full audience gathered for our symposium
One of the main attractions at BtS was our symposium The Science of Long-Lasting Regenerative Biomaterials: A New Dermal Bio-Activator Deliberately Designed to Regenerate, where our speakers explored different dimensions of regeneration.
Regenerative aesthetics are increasingly reshaping aesthetic medicine. In the first part of the symposium, Dr. Jani van Loghem discussed how these advancements affect clinicians and their treatment offerings. Dr. Jani van Loghem is an Aesthetic Physician and founder of the training centre UMA Academy.
In daily practice, aesthetic products need to be easy to administer. Already at this stage, clear differences can be observed between various PLLA-based biostimulators, where particle design plays a decisive role in achieving a homogeneous solution.3 Our speaker Dr. Pawel Kubik is an Aesthetic Physician and founder of the research centre K-LAB R&D.
Dr. Susanne Kristof is among the most experienced clinicians in treating patients with JULÄINE™. She presented the advantages of achieving a tightening effect without creating volume, including in cases of delicate skin.4 Dr. Susanne Kristof is a Dermatologist with over 15 years of expertise in aesthetic medicine.
