Q: Just received this rosehip oil and unfortunately it smells like rancid fish oil supplements. The smell is noxious when opening the bottle, but I tried some on my hand to see if the odor would possibly dissipate. Very wishful thinking as I smell like dead fish and it has been over 30 mins. Very disappointed.
