I have been using Bio oil for the past 12 yrs now, it has been my companion from after pubity stretch marks through to having 2 beautiful girls. During pregnancy I developed stretch marks that looked like purple slash marks, my 2nd daughter is now 1 yr old and from consistent use of Bio oil every night I can proudly say that patience is a virtue as I have only fine silvery lines. I also use Bio oil as a night treatment , for my daughters uneven skin tone through sunburn and even bruises or mosquito bites, this is a diverse product that works!
