Hi, I have to agree that if you're prone to them you will probably still get some but you can prevent a massive breakout all over if you keep well hydrated and moisturised as much as possible. It's not the moisture, it's the stimulation of the blood to the skin so rub vigourously and generate a bit of heat with the Bio Oil (I'd recommend this every evening and a Cocoa butter for the day times, less greasy on clothes).
Try to drink lots, I have a litre of water with every evening meal and two or three glasses with every other, so keep swigging back water.
If you do get them, don't be too hard on yourself - blame your mother! And remember, you can cover them up easy enough until they fade, after a year they'll be just silvery lines under the skin and you can call them your war scars from pregnancy - you'll be like millions of other ladies in the world and completely not alone!
