Query: I'm pretty sure this stuff is magical.

I started using the H2Ocean spray just hours after my new microdermal anchor piercing (which is now 3 days old) and there is absolutely no redness or swelling. I didn't use it right away with my first anchor piercing, and it took over 2 weeks for the redness and swelling to go down. I'm also using it to help heal a deep wound from having my first anchor piercing removed. The removal left me with a big crater below my collarbone and the H2Ocean is significantly speeding along the healing process. The hole was big enough that I contemplated getting stitches, but the skin is actually regenerating itself to close over the wound and it's happening quite rapidly. So, yeah... I'm pretty sure this stuff is magical. Cheers!
