When dealing with lip filler migration, the need to dissolve the filler before undergoing aesthetic lip surgery depends on various factors.

The extent of migration, the age of the filler, and the specific anatomy of your lips play crucial roles. In some cases, reducing or dissolving the filler might be necessary, especially if the migration is severe.

However, sometimes the migrated filler can stabilize the tissue, making it beneficial. An experienced surgeon can assess your unique situation and guide you on the best course of action.
