My Mumdoes not have one at all, she had 3 of us & ordered pure lanolinj straight from the sheeps backs, it stunk & she said it was hard to get back then, but she never got a mark at all, my older sister has had 3 preg's & has 2 kids, not a stretch mark at all, I have DD & a totally different body to my sisters & Mum, they are tall & very lean, I am shorter & have big boobs & hips, I have tiny unnoticable stretch marks on the under side of me breasts & also on top of thighs & on lower back/hips!
I don't care when I see what some other ones are like & also know I got them through lovingly carrying & giving birth to my precious DD! I wear them with pride like a badge of honour & know most of my friends that don;t have kids ahve much worse than I do!!

I put moisturizer on after every shopwer, but not to prevent stretch marks, just coz I like it!!!???
