This is my first time getting laser beard removal. How many sessions do I usually need to see 확실 results?

Hello. I am seriously considering laser beard removal due to the hassle of shaving every morning and frequent skin irritations. Many people around me have recommended it, citing great results, so I am planning to give it a try. However, I have a few questions, so I am writing to ask you first. I would like to know how many sessions are typically required and at what intervals to achieve a completely smooth beard. Also, I have heard that certain devices, such as the GentleMax Pro, are better in terms of pain and effectiveness; I would like to know if there is a significant difference depending on the equipment. I have heard that redness or irritation like folliculitis frequently occur after the procedure, so I am a bit worried that it might interfere with my daily life. I would appreciate any advice on how to manage daily skin care. It would also be very helpful to inform me of the approximate cost or if there are any promotions, such as one-time trial events, when deciding whether to visit a clinic. I know you are busy, but I look forward to your detailed response. Thank you!
