Steri-strips are good for closing up wounds. Keeping it clean and protected. Also keep an eye out for signs of infections.

Not that it helps any, but I've done some really deep cutting on my stomach (can't remember it but I have the scars). They obviously weren't treated in any way, and healed fine.

For when they start to scar up, I've found that coconut oil is good at helping them get soft and faded quicker.
