“The more hydrated you are, the more elastic your skin will be and it will bounce back immediately after pinching it.”
The trick is simple, all you have to do is pinch your skin - the time to bounce back is a reflection of 'how hydrated you are’ @dr.karanr (TikTok)
“If you’re dehydrated, the skin loses elasticity and it takes a while to return to normal and is more likely to tent up”
The video has since racked up 6.7M views and thousands of curious commenters.
Like many, one person had believed the trick to be a myth: “This is true? I thought it was an old wife’s tale. My gran told me this years ago”, she said.
One added: “When i was little I used to do this and was so proud for it staying up for so long”.
The revelation also prompted some users to up their water intake. “This made me drink 2 litres of water”, one said.
Some TikTok users were shocked at how ‘dehydrated’ they were TikTok
Dr Karan Raj added a disclaimer in the comments section to confirm that, while the principle behind the ‘pinch test’ is true, he cannot confirm whether the method in the original video is accurate. He said:
“FYI: I’m not sure the persons method is accurate and certainly not on the knuckle BUT the principle behind pinch test is correct!”
