The Outlook of the Development of Innovative Products from Biocompatible Natural Spider Silk in the Beauty Thread-Lifting Industry

Abstract

Embedding thread lift rhytidectomy, also known as “thread lifting” in China, with the natures of simple operation, less trauma and quick recovery, is progressively used in clinical practice as a new technology of face lifting. Herewith, a brief introduction of the previous advances of thread lifting techniques and materials in the facial beauty industry, combined with the discussion on various types of sutures, common complications, and the site of actions were provided. The main limitations of present thread lifting material include: (1) the use of non-absorbable sutures is liable to cause allergies and a series of complications; (2) the absorbable sutures are easily degradation, and people need to reshape in a relatively short period. Therefore, the high biocompatible spider silk was proposed as a novel material of thread lifting suture and related devices, the advantages and preliminary achievements on spider silk were also addressed.

Recombinant Spider Silk: Promises and Bottlenecks

“…It was reported that they can be used in lithium-ion batteries to retain the capacity and decrease the volume expansion of silicon ( Choi and Choy, 2020 ), for aerospace application ( Mayank et al, 2021 ), as vision-based vibration sensors ( Liu et al, 2020a ), silk-based humidity sensors ( Liu et al, 2020b ), or protein-based adhesives for transparent substrates ( Roberts et al, 2020 ). In addition, application of spider silk proteins in the cosmetic industry has been explored recently, for example as a new technology for face lifting ( Qing et al, 2021 ).…”
