My doctor actually told me that a good way to prevent stretch marks and to lighten them up is to take the Vitamin E pills make sure its the gel ones stick a needle threw it an sprinkle the gel onto your stomach you can spread it all over your stomach or just put them on stretch marks that are already there and it will lighten them. i myself have stretch marks on my stomach as well and i started to put the gel on my stomach an they really started to lighten up although i do recommend to get some playtex gloves because its very sticky and has a weird smell.(the odor from the pill juices)
My dr said that to some extent stretch marks cannot be prevented. I would suggest using Palmers more often, if possible. I don't have stretch marks on my stomach but I have them horribly on my hips and butt. I'm 31 weeks now, and I use Palmer's 2-3 times a day and I've noticed a difference from using it more often. Best of luck to you!!
u can prevent stretch marks i never had them with my 1st son am pregnant now 28 wks i believe and i dont think i have any if i get them so be it u can continue using Palmers and hope they are not to bad u can look at my pofile and see pics of my belly it's not so big though
