A closeup image shows marks of Macrons thumb and finger's on the US president's hand.
Other photos snapped of the men's hold shows Macron with a stern look on his face as he appears to pull Trump's hand towards his body.
"We have a very really good relationship, very special," Trump told reporters after Friday's handshake, according to Yahoo.
The picture of Trump's discolored hand quickly went viral, sparking hilarious reactions from social media users.
One Twitter user named Nick Wenmaekers tweeted that Macron won "the handshake game".
Another user, named Jimvj said the French president showed Trump "that 2 can play that game".
"It was Trump who transformed a simple handshake into a weird vomit inducing act of machismo: yanking the other person, & holding on for a very long time. Point, set & match to Macron," he posted.
Last July, at the Bastille Day celebration Trump shook Macron's hand before leaving and held on to it for an agonizing 29 seconds. Even as Macron tried to pull away, Trump kept a tight grasp on his counterpart's hand before eventually letting go.
