The shape and fullness of the lips have a significant role in facial aesthetics and outward appearance. The corrective needs of a patient can range from a subtle enhancement to a complete recontouring including correction of perioral rhytides. A comprehensive understanding of the lower face anatomical features and injection site techniques are foundational information for injectors. Likewise, the choice of filler material contributes to the success of the injection techniques used, and facilitates a safe, effective, and natural appearing outcome. The small-particle HA 20 mg/mL with lidocaine 0.3% (SP-HAL, Restylane® Silk; Galderma Laboratories, Fort Worth, Texas) is indicated for submucosal implantation for lip augmentation and dermal implantation for correction of perioral rhytides. Due to its rheological properties and smaller particle size, SP-HAL is a well-suited filler for the enhancement and correction of lip shape and volume, as well as for the correction of very fine perioral rhytides. This work is a combined overview of techniques found in the current literature and recommendations provided by contributing authors. <br /><br /> <em>J Drugs Dermatol.</em> 2016;15(9):1076-1082.
