Yeah, I did one of those silicon creams for a very little while. (It was given to me by a physio-therapist). It was kinda weird sensation and then I found out about the Siberian oil from "my main PT" and I liked it much better.
Scars are weird anyway. I mean as long as they don't go keloid on ya the dr's can't complain so use whatever is available and suits *you*. Some injuries you feel like Doctor knows best and some injuries you just want the nice smell and colour of Siberian oil. Best to stick with the plan tho' once you have found something you like. (You will know pretty quickly if you feel it's "for you" or "not for you". Healing Instinx)
You basically have a scale that starts at "primitive" (eg freshly peeled papaya skin, raw propolis), moves on through "natural" (eg Siberian oil, wheatgerm/Vit E oil ) to "state of the art medical technology" (eg silicon cream).
I've done them all at various times and would say they all worked too.
I've got the scars to prove it!
Keep us informed!
