Should I continue using at-home IPL? (M)

I'm on my second treatment. I shave before starting, and I feel a slight sting during the process, but it doesn't last the whole time. I'm treating my chest and thigh hair. So far, I haven't noticed any changes. I've read a lot of posts where guys say hair removal is tough, especially on the face. I was planning to use it on my face later——do you think I should keep going? Any tips to improve the results?
