Stretch Mark Remedies

I used palmers cocoa butter for my first pregnancy and have stretch marks on my chest, stomach and thighs. For my second I used vitamin E and the cocoa butter and still got more stretch marks. My sister used nothing for either of her pregnancies and doesnt have noticable stretch marks. We are very similar body types and both gained an average amount of weight. I think a lot of it depends on each individual's skin.
