I'm concerned about my pores. Please tell me the features of Potenza in detail!

Having lived my entire life with dehydrated oily skin, my biggest complex has been the gaping, orange-peel-like pores in my butterfly zone. No matter how good the primer I use is, by the afternoon it gets tangled with sebum, breaks down, and gets stuck in my pores, making me look so messy. Sigh. I'm seriously considering the Potenza treatment, which is called a "pore eraser," because I've heard it's the most effective. What are the powerful features unique to Potenza that clearly differentiate it from other Fraxel lasers? I've heard it hurts like crazy since it involves pricking with micro-needles, but if the skin becomes smooth enough to endure the pain, I want to grit my teeth and book an appointment this weekend right away. I'll be waiting for real tips from beauty experts who have successfully eradicated pores! Please, please!
