I've heard it's good to get laser hair removal done before summer. Does the effect really last a long time?

I get stressed about hair removal every summer, so this year I'm really planning to prepare in advance. When I shave, the hair grows back quickly, and my skin keeps breaking out, causing acne to pop up as well.

I tried waxing too, but it hurt so much that I can't do it anymore.

My friend highly recommended laser hair removal, saying it made things so much easier, so I'm looking into it too! How long does hair usually stay back after laser hair removal?

I have sensitive skin and tend to break out easily, so I'm worried that laser hair removal might be too irritating. I'm also curious how many sessions I would need to see definite results.

I think I need to start now to get it all done before summer. Please share your reviews if you've had laser hair removal!!
