Resembling many qualities of the "uncanny valley," a new trend on TikTok has begun going viral over the last two weeks for its bizarre aesthetic.

Known as the "Uncanny Valley Makeup Trend," this visual effect emerged on TikTok late last month, gaining virality after user @blonde.girlyy posted a video experimenting with makeup to achieve a "not human" appearance.

The trend has since grown on social media and involves creators sharing videos that aim to evoke an uncanny valley feeling, creating visual effects that challenge the traditional boundaries of human-like appearance.
