I use the oil instead of moisturise now. I use it every morning after my shower. Then at night after a shower. At night I spend more time rubbing it in and also put more on. I don't use a carrier oil as it's ok to put on directly onto your face as thats what the instructions on the bottle say.
I've recently heard of an even more potent scar healing oil which is just being marketed and produced. It is raspberry seed oil. Think it has more A, E and omega than rosehip or something. h
