There is no cure for stretch marks at present. The problem is that the collagen fibers of the tissue rip away from eachother. If you lightly slid your finger across the region you'll notice a slight depression just like some scars. The lasers, lotions/creams/etc cannot repair this. They can however lighten the discoloration along with plain old fashion time. Surgical removal is an option to remove multiple marks with the final result a surgical scar which may look better. As laser technology improves there may be hope some day. I agree, however, that providers probably don't mind very much. They seem to be much more concerned with hygiene.

Oh, in case your curious on why I know, I'm in the medical field and used to specialize in Dermatology.
