I'm a profesional beautician and I'd like to let you know that once we've stretch marks, thus the tissues of our muscles have been destroyed. We can only make them less visbible but we can NEVER make them disappear!
In order to be effective, the treatments must be made when the stretch marks are still in color pink-purple. If they're already in white, no hope then.... Sorry for my frankness!
You can try Alqvimia Body Sculptor which is very effective. And many BK mama used it. I know where can buy it with 20% discount, free delivery and credit reward. PM me if interested.
