Cartilage/Ear Lobe Piercing Questions?

I would seriously consider going to a shop, I know it's a somple piercing but with cartilage ones you need to use a hollowed needle not a gun, it makes a difference in the healing process and less chance of infections cause peoples blood gets on the guns and the ppl piercing army trained to clean them well.. Anyway enough about that, go to any tattoo and piercing shop or online and get h2ocean, it's a salt solution with a ton of properties to speed healing and kill infections
