secret for scar tissue ? hard to say. use small needle, go in slowly, inject slowly, massage well the area, use all the possible sites, make go rotation, have somebody (like a nurse) that knows well how to do it and where to do it... they have to take care of themselves.
I put oil on specific spots on my body after my showers, so I can keep my skin hydrated and flexible, so I don't get stretch marks. I use also a skin lotion with E vitamin before going to bed. It helps a lot your skin. The pros must use some of those skin lotions too.
anyway, as long as i don't get as freaky as Paul Dillett, I should be alright.
