In recent years, injectables have become increasingly popular in cosmetic procedures. The choice between using a needle or a cannula depends on several factors, including the site of injection, the filler type, the patient's preferences, and the practitioner's skills. Although needles are easy to use, cost-effective, and best for treating superficial rhytids, they may cause tissue injury. Cannulas are safer, particularly when injecting deep to the bone, and can provide more even distribution of filler material when filling large zones. An in-depth understanding of the facial anatomy and ongoing training are crucial for practitioners to develop and improve technical abilities.
