Lip augmentation procedures typically utilize injectable substances to enhance volume and shape. The predominant component in these dermal fillers is hyaluronic acid, a naturally occurring polysaccharide found throughout the human body. This substance attracts and binds water molecules, providing a plumping effect in the treated area. Certain products may also incorporate lidocaine, a local anesthetic, to minimize discomfort during the injection process.
The widespread adoption of hyaluronic acid-based fillers stems from their biocompatibility and reversibility. The body gradually metabolizes hyaluronic acid over time, resulting in temporary augmentation. Furthermore, in the event of undesirable outcomes, hyaluronidase, an enzyme that breaks down hyaluronic acid, can be administered to dissolve the filler and restore the original lip volume. Historically, other materials such as silicone and collagen were used; however, hyaluronic acid has become the preferred choice due to its safety profile and predictable results.
