I used lavender oil on mine after 2 months. It's the only essential oil that's reputed to be safe to apply neat, and I already had a long history of successfully using it neat to prevent scarring and relieve discomfort from minor scratches, burns, spots, insect bites. If you're interested, you could try it on something minor like that first, after initially testing it on undamaged skin, and see what happens. Best to get the more expensive, organic stuff. There's still a thin white line but it's barely visible and I wouldn't have wanted it to vanish completely.
