umm also bio oil does last a long time!!! i was using it when preggers and i was placing it on my face, tummy, sides, thighs, back of legs my bum and the back of my thighs and i was doing this twice a day everyday, the larger bottle lasted me 2.5 weeks!!! so i thought that was great!!! also there are serums out there u could try but they tend to get sticky!!!
