Use clay to draw out any toxins in the area, then use raw honey, not just organic honey, but but 'raw' with everything included. I can't tell you if it works for pitted scars though, sorry.
As for Sea Salt , a mild mineral solution will help your skin as it can soak up some of the minerals in the tissues, it cycles so more MAY come out -- so only do this when there aren't any toxins but you just want to feel refreshed, etc.
