METHODS: A group of doctors with various specialties, who have used VYC-25L extensively since it first became available in their countries (3-5 years), share clinical experience and guidance on optimal use.

RESULTS: VYC-25L has a unique rheological and physicochemical profile that provides elevated lift capacity and enhanced projection, significant moldability immediately after injection, high levels of tissue integration, reversibility with hyaluronidase, and a long duration of clinical effects-typically lasting at least 24 months. The properties of VYC-25L have created new possibilities for nonsurgical facial medical aesthetics. However, as with any novel product, it is important that injectors recognize how best to use it for the benefit of patients. When first utilizing VYC-25L, it is advisable to start with the chin and jawline to gain familiarity with the gel characteristics before moving into other facial areas, and to consider splitting treatment over two or more sessions. Attention must also be given to injection volume, with less product typically required with VYC-25L compared to other fillers with similar indications. Key principles of good practice should be followed, including appropriate patient selection and pretreatment education, suitable choice of injection device and plane, aseptic technique, slow and careful administration method, and sufficient posttreatment follow-up.
