3D Printed Hollow Microneedles for Treating Skin Wrinkles Using Different Anti-Wrinkle Agents: A Possible Futuristic Approach

The document explores the potential of 3D printed hollow microneedles (HMNs) for treating skin wrinkles by delivering anti-wrinkle agents directly into the skin, offering advantages over traditional methods due to their minimally invasive nature and ability to bypass the skin's protective layer. Studies have shown promising results, such as a 31% reduction in skin texture irregularity in a study with 60 patients using microneedles for collagen delivery. The paper highlights advancements in HMN fabrication techniques, including 3D printing methods like two-photon polymerization and stereolithography, which enhance precision and reduce costs. Despite challenges in manufacturing and issues like short duration of action, HMNs are seen as a promising approach for skin rejuvenation, offering controlled drug release and minimizing adverse effects.
