(IPL, philips lumea 7000) Will setting 2 even have an effect on the hair?

I don’t know if my pain tolerance is low but I just can’t handle settings 3,4, or 5. They hurt too much.

So i’ve been using setting 2 which was still a bit painful but more manageable. I am worried though, if i’m wasting my time.

i’ve got brown skin + black hair for context.
