[3] [4] Korshunova established herself as a rising figure in the fashion industry by posing for magazines including Vogue and designers such as Vera Wang and Nina Ricci.

She also modeled in print-ads for Nina Ricci, Blugirl by Blumarine, Clarins, Ghost, Girbaud, Kenzo Accessories, Marithé & François, Max Studio, Moschino, Old England, Pantene Always Smooth, Paul Smith and Vera Wang lingerie.

[3] In 2006 Korshunova appeared on the cover of Vogue Italia "Broken dolls" along with Vlada Roslyakova photographed by Patrick Demarcheleir.

[17] On 28 June 2008, at around 2:30 p.m., Korshunova died after falling from the ninth-floor balcony of her apartment at 130 Water Street in the Financial District of Manhattan, US.

One of Korshunova's friends stated that she had just returned from a modeling job in Paris, noting that she seemed to be "on top of the world" with no apparent reason why she would commit suicide.

According to the testimony of many witnesses, no strangers or suspicious people were noticed on the day of Korshunova's death in her building on Water Street.

"[25][26] In January 2024, documents about sexual predator Jeffrey Epstein were published and it was revealed that Ruslana visited the island two years before her death.

[27] [28] British TV producer and filmmaker Peter Pomerantsev has theorised that Korshunova's suicide was related to her involvement with Rose of the World, a controversial Moscow-based organisation which describes itself as "training for personality development".

While researching for a documentary into Korshunova's death, Pomerantsev learned that the model spent three months attending training sessions at Rose of the World.

These sessions—which encourage participants to share their worst experiences and recall repressed memories—are modelled after Lifespring, whose controversial methods were the subject of multiple lawsuits for mental damages in the US during the 1980s.

Korshunova attended training sessions with a friend, Ukrainian model Anastasia Drozdova, who committed suicide under similar circumstances in 2009.

Korshunova became aggressive, while Drozdova experienced violent mood swings and grew reclusive; both lost weight.

Rick Alan Ross, head of the Cult Education Forum, argues that organisations such as Rose of the World "work like drugs: giving you peak experiences, their adherents always coming back for more.
