ok so did a bit of reading on the cross method i use 100% tca on an icepick scar and make sure not to hit the edges of the icepick scar just literally only the middle of the icepick scar. and you do this by stretching skin before appying it with a toothpick and you keep it stretched until your skin frosts then you can let go.

did i get the right info? and if anyone has any other tips from their experience with tca cross method let me know please thanks in advance

If you are anything like me- scars ranging in size- it is necessary to file down the toothpick so it is somewhat blunt, and fine enough to go into the middle. Some of my scars no matter how much I stretched the skin it would touch the sides/frost the edges. I haven't noticed any additional damage on the scars where it touched the sides though.

Might help to use a lower percentage and layer so you have more control of where the acid is going at first.

i wouldnt recommend doing it by yourself at home
