In 1813, Wacklin moved to Åbo (Finnish: Turku) where she studied French and music while being active as a governess.
Between 1815 and 1819, she worked as a governess in several families in Southern Finland, notably at the Governor of Tavastaland Gustaf Hjärne.
In 1819, she finally made her study trip to Sweden, and upon her return, she settled in Uleåborg, where she opened her first school for girls.
While their school was a traditional girls' pension with focus on accomplishments similar to that of Christina Krook, of which there were many in contemporary Finland, it was somewhat more progressive than most, as it had a two-year course and tutored in other languages than French as well as in several subjects also tutored to boys, rather than exclusively accomplishments and household tasks.
In 1835, she closed her school and traveled to France, where she took a course for female teachers at the Sorbonne University in Paris.
Her school was very popular, and Wacklin became economically independent and an important member of the middle class social life of the city.
