Little white bumps that look like pimples all over chin and neck area after laser hair removal?

I recently got laser hair removal on my chin and neck area. This is my first session in years since I stopped doing the treatment. I never remember having had a reaction like this after laser hair removal on my face. I got it done yesterday and now today my chin and neck area are filled with white puss filled bumps that look like pimples, and I don't know what I should do. The doctor did switch to a more stronger laser than the last time. Also, my skin is very oily and sensitive .
