I did pico toning about 6 times. At first, my face was very red and itchy. I was worried a lot ㅜㅜ But it didn't happen the second time. Is it effective until the 4th time? I thought it was Gingaminga These days, I see that a lot of blemishes have definitely been removed. It seems like my face has become whiter too. This is my first time using a laser and I thought this is how I take care of my skin!!
