Introduction1 In the context of thread lifting, the term “thread” denotes a material that is thin, slender, and fine. This terminology carries connotations of strands that are twisted to produce elongated lines, typically employed in the manufacture of textiles such as clothing, fur, cotton, silk, nylon, and similar materials. Consequently, any substance structured as thin and elongated lines might be broadly classified as a form of thread lifting procedure.2 However, from the material perspective of utilized surgical or procedural materials, they can be categorized into materials resembling sutures used for tissue closure (commonly known as threads in the form of monofilament and cog threads) and materials differing from those configurations.3,4 Thread lifting was first introduced by Sulamanidze et al in the 1990s.5 Initially, conventional sutures led to poor longterm efficacy.6 To address this, barbed sutures known as Aptos threads were introduced, which improved the effectiveness of thread-lifts.[7 ] Several variations of thread-lifting techniques have been developed subsequently, such as ptosis, Isse Endo Progressive Facelift Sutures, Silhouette Sutures, and Contour Threads.8,9 These advancements have gained popularity among aesthetic practitioners.10–15 The authors perceive a notable gap in understanding regarding thread lifting materials within the field of aesthetic procedures. Recognizing the increasing relevance of thread lifting in contemporary clinical practices, the aim is to clarify the diverse characteristics and implications of various thread materials. Through this review, the objective is to equip practitioners with the requisite knowledge to make informed decisions and optimize clinical outcomes in thread lifting procedures.
