Background: Hyaluronic acid (HA) fillers are commonly used in treating facial wrinkles and folds but have not been studied with standardized methodology to include assessment of standard facial expressions.
Objective: To assess perceived naturalness of facial expression after treatment with 2 HA fillers manufactured with XpresHAn Technology (also known as Optimal Balance Technology).
Materials And Methods: Treatment was directed to the nasolabial folds (NLFs) and at least 1 additional lower face wrinkle or fold. Maintenance of naturalness, attractiveness, and age at 1 month after optimal treatment were assessed using video recordings and photographs capturing different facial animations. Global aesthetic improvement, subjects' satisfaction, and safety were also evaluated.
Results: The treatment was well tolerated. Naturalness of facial expression in motion was determined to be at least maintained in 95% of subjects. Attractiveness was enhanced in 89% of subjects and 79% of subjects were considered to look younger. Most subjects assessed their aesthetic appearance as improved and were satisfied with their treatment.
Conclusion: Naturalness and attractiveness can be assessed using video recordings and photographs capturing different facial animations. XpresHAn Technology HA filler treatments create natural-looking results with high subject satisfaction.

An improved face attributes editing method based on DDIM.

College of Big Data and Intelligent Engineering, Southwest Forestry University, Kunming, 650224, China.
The main advantage of DDIM is that it guarantees the quality of the generated images while increasing the efficiency of the generation by modifying the sampling strategy in the diffusion process. DiffusionRig, which addresses the problem of maintaining identity consistency by learning the person-specific facial prior in a tiny personalized dataset, is a successful representation of the DDIM strategy. Based on DiffusionRig, in this article, we propose an improved face attributes editing method based on DDIM to improve naturalness and accuracy of editing results in complex face attribute editing tasks and the generalization ability.
