Wiik was born in Helsinki. She was the daughter of architect Erik Johan Wik (or Wiik) (1804–1876) and his wife Gustava Fredrika Meyer. She was born and grew up in Brunnsparken and attended the Swedish language school Svenska fruntimmersskolan in Helsingfors. She then studied drawing with art professor Adolf von Becker.
Encouraged by her family, she studied art during 1874–1875 at the Academy of Fine Arts in Helsinki. In 1875, she continued her art studies in Paris under Tony Robert-Fleury at the Académie Julian, one of the few private schools accepting women at the time.
Her painting Out into the World won a bronze medal at the Exposition Universelle (1900) and was included in the 1905 book Women Painters of the World by Walter Shaw Sparrow.
