TikTok has introduced a new face filter called "Bold Glamour", which uses machine learning technology, including Generative Adversarial Networks, to create subtle and seamless facial modifications that appear to move with the person's face, rather than become distorted by hand movements or other obstructions. The effect has gone viral on the social media platform, with over 9 million videos using the filter shared already. While some are impressed with the technical achievement, others are concerned about the impact of even more advanced AI-powered facial modification tools on users' self-esteem and sense of self. TikTok has not confirmed the use of AI in the filter's creation.
