Plucas,
I don't believe that anything can really heal stretch marks. I think most of weather or not you get stretch marks depends upon genetics and how elastic your skin is. That said, I have given birth to two children (went from tiny to huge each time), and didn't get a single stretch mark. This is what I did:
1) Focused on prevention rather than getting into the situation of dealing with stretch marks after they made an appearance.
2) took vitamin e tablets
3) Ate
wheat germ daily (high in vitamin e plus ate lots of vitamin c)
4) Overall ate extremely healthy
5) Worket out lots
6) used vitamin E lotion on my skin
I think that the topical treatment (vitamin e lotion) was probably the least effective. I think that what you take into your body internally is far more important
