%X Minimally invasive forehead augmentation is becoming increasingly popular in Asia. However, treatment of the glabella is associated with injection-related complications. The safety of injections can be increased through a thorough understanding of the anatomy and precise injection planes. The authors propose a 3-point injection technique for forehead augmentation in Asian patients that uses CHAP-hyaluronic acid (CHAP-HA) filler. The longevity of the filler was assessed using high-resolution ultrasound (HRU) imaging. Fifteen patients were examined using HRU before and immediately after treatment and at 1 month, 3 months, 6 months, and 12 months. As evident in HRU imaging, CHAP-HA remained visible within surrounding tissue for 6.4 ¡À 3.7 months. The mean Global Aesthetic Improvement Scale rating was 2.4 ¡À 0.5 immediately after treatment, 2.8 ¡À 0.3 at 1 month, 2.7 ¡À 0.5 at 3 months, 2.1 ¡À 0.6 at 6 months, and 1.5 ¡À 0.6 at 12 months. Minimal side effects were reported. The authors demonstrated that CHAP-HA filler may be an optimal candidate for forehead filler augmentation using a 3-point injection technique.
