Helgesson began skating at the age of three, following in the footsteps of her mother. She is coached by her mother and Regina Jensen. At the age of 12, she landed her first triple jump, a
Salchow. Helgesson competed at the 2004
World Junior Championships, where she came in 22nd. In 2007, she won the
Swedish national title for the first time at the senior level. She again competed at
Junior Worlds, finishing 28th. In 2008, Helgesson made her
European Championships and
World Championships debut, and came in 18th at both events. She improved upon her result at the
2009 European Championships, but failed to qualify for the free skate at that season's
Worlds, and was thus unable to qualify an Olympic berth for Sweden. In 2010, Helgesson finished 11th at the
Europeans. Two months later, she improved her personal best by 19 points to finish tenth at
Worlds. She consequently received two Grand Prix assignments in the 2010–11 season, the first of her career; she finished 9th at the 2010 NHK Trophy and 6th at that season's
Skate America. She medalled at two international events, the
2010 Nebelhorn Trophy and the 2010
Merano Cup, and improved to 6th at the
European Championships, the best finish by a Swedish figure skater since 1932. She was 17th at the
2011 World Championships. In addition to Sweden, Helgesson also trained in Colorado and Boston. She began the 2011–12 season at the
2011 Nebelhorn Trophy, where she finished 5th. In October 2011, Helgesson won the bronze medal at the
2011 Skate America, her first medal at a Grand Prix event, as well as the first by any Swedish skater. She achieved a career-best European placement, 5th, at the
2012 and
2013 European Championships. Helgesson represented Sweden at the
2014 Winter Olympics in
Sochi. She placed fifth at the
2015 European Championships in
Stockholm, Sweden. In April 2015, she retired from competition. == Programs ==
