Did more than I had even hoped for
I have been applying this specific product for about two years now. In the initial months, the bright red colour of the stretch marks faded. Over two years, they are now very faint and only the most severe parts of the line are still visible. The fainter lines are now only about 8cm long.
While I'm curious about trying other products, I'm not sure I want to when this one has been so helpful. I like the light scent, too. I imagine if you used this as a preventative rather than a cure, it would be even more effective.
