I got heaps of stretch marks, after about a year they faded to pale and silvery. I knew I would get them as I got some from a growth spurt when I was 13 all up my legs and hips.
I used coca butter but I don't know if they would have been worse without it.
I got more in second PG as I was always lifting DS. I think they show up more when its cold. I have old scars from years ago that show up purple when I'm cold too. I've got that lovely lily white skin!
