When we were still living in that old apartment, we were not aware that the place was infected with bed bugs. We started noticing some bug bites mostly in our legs after a week since we moved in. Good thing some of our stuff was still in the box. We bombed the whole place for two weeks. I bought a bio oil that helps removed the bug bites scar. I really don't know if the bio oil can also be an acne scars removal because I didn't try it on my scar. All I know was the nasty scar from the bed bug bites had clear up. I can highly recommend Bio Oil for scar. It’s a good stuff.
