Police in Haringey tweeted an appeal: "Can you help to find Marina Joyce, 22, missing from Haringey?"
The Internet personality was reported missing on August 7 and was last seen on July 29.
The hashtag #SaveMarinaJoyce began trending on Twitter in the United Kingdom and U.S., which lead to the police getting involved at the time.
The lifestyle vlogger, who boasts over 2.1 million subscribers on the video-sharing platform, was last seen on July 31st in her home in Haringey, North London. But now, nobody knows where she is and that is starting to worry everyone.
The Met Police have issued advice, saying: "Marina Joyce, 22, was reported missing to police on Wednesday, 7 August".
The announcement follows a social media post by her boyfriend Brandon Mehmed on Friday night in which he said "she is safe and well".More news: Orioles’ Brandon Hyde, Chris Davis Involved In Heated Dugout Kerfuffle

Fans of Joyce undoubtedly helped with the search, with her name trending on social media after news of her absence was spread.
When contacted by CNN for clarification Mehmed said she had been found by police, which London's Metropolitan Police then confirmed. She posts fashion, beauty, dating tips, and makeup tutorial videos to her YouTube channel.
Marina last updated her Instagram and YouTube accounts in late June.
Online sleuths became obsessed with conspiracy theories about the young star, which she later addressed in a personal video on her YouTube page - Saving Marina Joyce - where she spoke about her depression.
The hashtag #SaveMarinaJoyce was shared over 3 million times before Joyce tweeted that she was "TOTALLY fine". "It hurts me up to this point to think of all the rudderless things I've done that I haven't taken care of", she clarified. "I'm getting better now, which is why I decided to make this video".
