gibberj2,
There is no cure or quick-fix for stretch marks I'm afraid. Not that people haven't been looking for one, the pharmaceutical industry reckon even a preventative against stretch marks would be worth tens of billions of dollars a year. Every pregnant woman would pay whatever it took to get their hands on it.
Some interesting facts about stretch marks:
-UV photography has shown that nearly 90% of the population (over 25) have stretch marks in their armpits.
-the length and width of stretch marks depends not only on muscle (fat) mass, but also on muscle structure (the longer the front deltoid, the greater the extent of stretching)
-stretch marks extending across the pectoral are most likely to tear (ie: become wider than 1/2 inch and require stitching)
However, there is one little trick I've kept up my sleeve... one that works quite well... vitamin E.
Simply cut open a 400 iu vitamin E capsule and rub the oil (daily) into the reddened area of the stretch mark, this speeds up the healing (scarring) process and can even take the redness out of old stretch marks.
Good luck,
The Luke
