It's been 2 years since I had the forehead reduction surgery. I reduced it by 1cm, but I can measure the data, so I'm really satisfied with the effect . ㅠ I think it would have been better to reduce it a lot from the beginning ㅋㅋㅋㅋ The sensation didn't exist until 6 months and it comes back little by little , but now the sensation has returned and there is still a little bit of pain when I touch it .
