- Mentor Extra High 6-month review - I am 155/40 and had 355cc joints placed equally on both sides. If I had to point out one of the inconveniences, I was scared because there was a tingling pain every now and then, but when I inquired at the hospital, they said it hurts when the nerve comes back, so that's it now. Haha. However, because I was not very fat and my skin was thin, I developed stretch marks, so I received a laser treatment for stretch marks at Kirin Plastic Surgery and applied stretch mark cream diligently, and they seemed to be getting better little by little..!! Even if you are bothered by stretch marks like me, I think it would be a good idea to apply stretch mark cream. When the stretch marks were severe, I slightly regretted it, but now I only apply 100 percent of the marks again, and when I lie down, I feel a slight foreign body and it is heavy because it appears like something that wasn't there before, but I am gradually getting used to it and when I wear clothes. Your body is really different... If you are worried about surgery, I recommend that you do it as soon as possible!
