Mostly on my stomach and inner thighs. If you are getting stretch marks just simply from small changres in weight you really need to change your diet and include more benefitial omega 3's, and more fruits and vegetables. This will help your body heal and prevent stress to your skin. Once you have them there is little you can do with out tons of money for laser treatments and tummy tucks, but one thing i found is to help the skin retighten. Eat well and try an exfoliating scrub with fine coffee grinds in it. Use it every other day. The stimulation of the skin will help with the redness and the caffeine will help with tightening the skin back up. It takes time for your body to heal it's self so don't expect results overnight. Here is my recipe for a coffee sugar scrub
gently heat 1/4 C castor or olive oil with 1/8 cup coffee grinds. Let warm for 20 minutes. Strain out the coffee grinds with a strainer and save the oil. add the oil to about 1 and 1/2 cup finely granulated sugar like C and H brand. I do not mean powdered sugar. mix it with a fork and store it in a tupperware type container with a lid. Keep it in the shower and use it every other day.

That is very true, stretch marks do not come just from pregnancy they can be there from weight gain and of course leave the skin stretched so that if you do lose weight the skin does not go back to normal. That is when they have to have weight loss surgery skin tucks which can be painful and leave scars.

It is true that sudden weight changes is the main cause of stretch marks. And the best remedy to them is good eating habits and regular exercise.

One thing that I think is very good for stretch marks and for other scars on the body is vitamin e oil. This is a natural healer for the skin and if you use it consistently over a long period of time massaging it in and the skin around the area as well then I think you can expect good results. But you do have to keep at it and spend time with the massaging.
