Enstilar for 6 year Old

Hello, My 6 year old daughter has really bad psoriasis and she is waiting to be assessed for the injections. In the mean time the doctor has give her Enstilar foam to try but said it is not tested in children but he thinks she should give it a try. On all the leaflets its say not to be given to anyone under 18. Just wondering if anyone has tried this on their child? Thank you
