Not sure if they used enough joules on my laser treatment with Lightsheer XC Diode

I did my first session 3 days ago. My skin is pale but not too much and my hair is black. For my bottom legs ,stomach and brazillian bikini area she used 17 jouls . for my upper legs she used 26 jouls. I wanted to know if thats enough to get the results i want or to ask to rise the houls in the next sessions. Really important for me please answer! Thanks :)
