I've heard one can eliminate stretch marks via skin brushing. Can someone tell me more about how this works -- i.e. when you get rid of the stretch marks via skin brushing is it because you are you restoring the underlying health of the skin?

I found this definition of stretch marks in a google search:

Stretch marks are caused when the skin is stretched to the point of breaking down, similar to elastic losing its' elasticity. Losing collagen and elastin in the skin causes stretch marks, loss of tone, fine lines and wrinkles. When there is a breakdown or loss of elastin and collagen fibers or excessive stretching in the skin, the mark actually shows through to the
epidermis (top layer of skin).

Your answer doesn't need to be in detail. I'm basically just wondering whether elimination of stretch marks has health benefits (and thus whether it's worth my while, since I don't want to do it for purely aesthetic reasons).
