I have uneven skin caused by boxcar and ice pick scars.

I was thinking about doing saline injection at home, but I read several reviews saying that it worsened the scar.

My scars are really old, at least five years or longer. Would the treatment be effective?

Lastly, what exactly do I need and where do I buy them?

I searched a little and it seems like I need 0.9% injectable saline solution and 30 g syringe.

Would this from Amazon work or is it better to go to local drug store (CVS, Walgreens, etc) and buy them there?

I assume if I were to buy this from Amazon, I need buy needles separately, and where would I get those? (ugh)

If anybody has tried before, please share your story. Thanks.
