It has now been about 10 days since I needled the scars. I have seen advice saying to needle only gently, but to be brutally honest, I've lived long enough with the damn pits that I went all in - I needled it like crazy with a 1.8mm needle, literally about 20+ times at least, and then I stamped the area very aggressively all around the pits with a 1mm. It bled quite badly after all this.
I didn't want to post results prematurely as there will always be swelling. When the scabs fell off, it looked the exact same depth with no improvement...again. But now since the scabs fell off 5 or 6 days ago, it actually appears to be very slowly improving daily. I'm using Copper Peptides everyday in the morning (the genuine, 1st generation copper peptide ghk-cu). I actually only noticed this morning when I look in my bathroom mirror - and it's one of those awful fluroesent tube lights that makes everything look awful - that the pits are most definitely not as obvious when I stand 1 meter from the mirror as they used to be.
So far it's too early to call it conclusively but it appears to be working. The only difference between this and my first time is using the real copper peptides.
