Bleach, a chlorine-based cleanser, effective for stubborn stains on clothing and fabrics, is being misused by teens through a popular app called TikTok. The app allows teens to showcase various talents and gain popularity based on likes. A concerning trend, labeled the “bleach phenomenon,” suggests that holding a bag of bleach to the face can change eye color. Despite being erroneous and dangerous, some TikTok users endorse the idea. The trend involves editing videos to convince others of its effectiveness. Some even substitute bleach with hand sanitizer and shaving cream. While the TikTok fad is popular, its short-lived nature often leads to the emergence of new trends. The app, with over 500 million viewers, continues to attract teens globally, raising concerns about potential future challenges.
