Interesting. I got some of this. Funny as I am all sciency about stuff. A friend of a friend of mine got it and liked it. I don't believe anything but silicone is more than a little effective (so lots of things might work a little bit). I don't hold much for vitamins or onions (Mederma). But something with enough silicone would work regardless of the scar.
But here was my thoughts. It has silicone. I haven't been really happy with any form of silicone I have used so far (strips and Scarguard) and the reviews of lots of them are not so good (sticky, smelly, peels off, etc.). I actually really like it so far, but it really depends on if I get a month and half worth off it. If I don't it isn't really worthwhile, and if I do it is. I'm comparing the price to like ScarGuard, which I actually did not get a month out of, so maybe that's not fair. I probably got a month out of Scar strips.
The thing is you really can't tell how much is in the bottle. It has a really expensive looking cosmetic type bottle. I think the bottle's purpose might be that you get a more or less (very more or less) even squeeze (and perhaps to keep you from figuring out how much is left).
It is nice to apply, has a very nice smell (licorice, which I don't believe has any magic traits), and seems to stay on. It rubs on so this is hard to tell but there is a bit smooth feeling over the scar that seems to last all day. I applied some on earlier. The scar has a smooth feel to it.
I'll let y'all know how well it lasts.
