Early life
Vorontsova was born in Leningrad (now Saint Petersburg), the elder daughter of Vladimir Putin and Lyudmila Putina (née Shkrebneva). She attended German school at Dresden, East Germany, while her family lived there in the 1980s. After her family returned to Leningrad in the spring of 1991, she attended Peterschule (Петершуле), a German gymnasium in Saint Petersburg. Later, during violent gang wars involving the Tambov Gang while it was taking control of Saint Petersburg's energy trade, she and her sister Katerina were sent by their father, who feared for their safety, to Germany where their legal guardian was former Stasi Matthias Warnig, who had worked with their father in Dresden as part of a KGB cell and established the Dresdner Bank branch in Saint Petersburg.

She played the violin for a Russian consulate general of Hamburg–sponsored diplomatic breakfast in 1995. Later, after her family moved to Moscow, she attended the German School Moscow, a school closely associated with the German Embassy in Moscow for children of diplomats. She graduated after 11 years of school. Three years later, she began her university studies, enrolling together with Katerina as first year students.

Studies and career
Vorontsova studied biology at Saint Petersburg State University and is a graduate of medicine at Moscow State University in 2011. With Ivan Ivanovich Dedov (Иван Иванович Дедов) as her advisor, she was a PhD candidate at the Endocrinology Research Centre in Moscow, headed by Dedov and which runs the charity project Alfa-Endo, for children with endocrine diseases. Alfa-Endo is funded by Petr Aven and Mikhail Fridman's Alfa-Bank of the Alfa Group.

She also, in 2015, co-authored a book about idiopathic stunting in children. Vorontsova is credited to be Putin's advisor in genetic engineering, especially in the usage of CRISPR to create genetically-engineered babies.

On 6 April 2022, following the Russian invasion of Ukraine, the United States Department of the Treasury sanctioned Vorontsova, stating that she, "leads state-funded programs that have received billions of dollars from the Kremlin toward genetics research and are personally overseen by Putin." She is also sanctioned by the European Union, the United Kingdom, Japan and New Zealand.

Vorontsova married Dutch businessman Jorrit Faassen in summer 2008 in Wassenaar in the Netherlands. They have a son, born August 2012. In 2013, they were living in a penthouse atop the highest residential building in Voorschoten. In 2014, Dutch residents called for Vorontsova to be expelled from the country after Malaysia Airlines Flight 17 was shot down by pro-Russian rebels in Ukraine. In 2015, Vorontsova and Faassen were reported to be living in Moscow. In 2022, it was reported that they are no longer married.
