Starting at the very young age of four, she has modeled for various German brands. Upon studying ballet at the German Opeara for fifteen years, she shifted her focus to Jazz, Hip-Hop, and Modern Dance.
Her desire to combine her studies so far with an acting education led her to move to Istanbul in 2010. This was when she started taking classes from the 'BKM Mutfak' team led by director Yilmaz Erdogan. Tosun then furthered her acting education at the 3 rd Mota School, where she took classes from Umit Cirak.
She started her acting career in 2011 with the TV show 'Kucuk Hanimefendi'.
