First Insights on the Upcoming Role of Next-Generation PLLA-LASYNPRO™ in Aesthetic and Regenerative Medicine. A Survey of Experts—Foundations and Rationale

How injectable collagen stimulators promote the neosynthesis of collagen and other components of the extracellular matrix in connective tissues has typically been linked to an inflammatory foreign-body reaction (FBR). A shift from the long-dominant inflammatory FBR paradigm to a new focus on non-inflammatory collagen and extracellular matrix regeneration may have emerged with the next-generation PLLA-LASYNPRO™ microspheres of the CE-approved JULÄINE™ medical device, which preclinical studies suggest are negligibly likely to trigger inflammation. A survey and subsequent discussions during a board meeting held in Milan, Italy, which involved thirteen distinguished experts in micro-invasive aesthetic medicine, aesthetic plastic surgery, and dermatology, led to this document and the accompanying manuscript “First Insights on the Upcoming Role of Next-Generation PLLA-LASYNPRO™ in Aesthetic and Regenerative Medicine. A Survey of Experts — Practical Suggestions”. This first paper outlines the initial insights and discussion of the experts on the basis and the value of the non-inflammatory rationale proposed for PLLA-LASYNPRO™ subdermal implants in aesthetic and regenerative medicine.
