This study aim was to evaluate the effect of injection of fillers in lips using hyaluronic acid on nasolabial angle and mentolabial angle. Methods: A total of 25 females aged between 19 and 40 years were enrolled in this study. Hyaluronic acid was injected to improve their lips. The nasolabial angle and mentolabial angle were evaluated by comparing the photographs taken before the injection, two weeks after and two months after. AutoCAD 2017 engineering drawing program was used for image processing and dimensional calculation. The T-Student test for a paired sample was used to compare the measurements of the studied variables between the three time periods of the study. Results: There was a statistically significant difference (p value <0.05) when using hyaluronic acid in lips augmentation on the nasolabial angle and mentolabial angle. Conclusions: The injection of hyaluronic acid for lips augmentation decreases both nasolabial angle and mentolabial angle. The amount of the decrease did not affect the aesthetic of the face in profile view. However, the amount of decrease in both the nasolabial angle and the mentolabial angle must be taken into consideration before injecting fillers into the lips.
