Clinical Trial Summary

The Research Question of the present study is the following: in a population of men and women presenting dermal tissue defects (scars, atrophic scars, depressed plaques, and lipodystrophy defects) will Plenhyage® significantly improve the appearance of treated areas, results observed after 4, 8 and 12 weeks?

Description:

Plenhyage® is a different type of dermal filler, an innovative course of polynucleotides to restore skin damage. The polynucleotide chain attracts water molecules, protecting against free radicals, acting as an absorber of hydroxyl radicals OH, which accumulate from stress, cell damage and UV rays. It also guarantees moisturising action and protection against free radicals. Nucleotides, natural fractions of DNA and RNA, are components of Plenhyage® with an antioxidant, protective effect. These characteristics allow Plenhyage® to be used as a temporary filler for subcutaneous areas to correct small defects in the dermal tissue due to lipodystrophies or the presence of fibrotic tissues as scars, caused by pathologies or trauma.

Intervention

Device:
• Plenhyage
Plenhyage® is an elastic, sterile, injectable, non-pyrogenic, re-absorbable gel made with polymerised polynucleotides (PDRN) of animal origin (fish). Due to its hydrophilic and polyanionic nature, PDRN binds water molecules, thereby filling intradermal spaces and making tissues firmer and more hydrated. The polynucleotide chain binds water molecules, has an anti-free radical action, and serves as a scavenger of hydroxyl radicals (OH), which accumulate under stress or due to foreign agents, such as UV radiation. Its hydration and anti-free radical activity help create the optimal environment for fibroblast growth, thereby restoring tissue elasticity. Plenhyage® is a colourless gel contained in a pre-filled, graduated, disposable, and sterile syringe with a Luer Lok adapter.
