Lip fillers are a popular cosmetic treatment that uses injectable dermal fillers to plump and shape the lips. The fillers used in lip augmentation are typically made of hyaluronic acid, a naturally occurring substance found in the body that provides volume and hydration to the skin. They have become increasingly popular recently, and for a good reason. They offer a quick and easy way to enhance the appearance of your lips and achieve a fuller, more defined smile. However, before you book your appointment, you must know a few essential things to ensure your lip filler experience is safe, effective, and enjoyable.
