TCA Cross 80% to treat ice pick and box scar

Hey guys it’s been 10 days and the scabs are all gone, my scars looks the same but I’m trying to be patient and wait until the 4 week to see any change. I don’t see any PIH. During the 10 days I used a replenishing cream and sunscreen. If I went out always wear a hat or Umbrella !

Im 33 years and I have ice pick and box scar on my 20’s
I tried 1 CO2 laser, 8 dermapen and I saw 0 result on the scar so I decided to give a try to the tca cross.
I prep my skin 3 weeks before with 4% hidroqui and retinol and I used a sharper tooth pick.
