So many brands are bringing out Lip oil’s at the moment. Are they worth the money? Has anyone noticed a remarkable difference from using a lip oil? What are they actually meant to do? I have seen Dior have a popular lip oil I have tried reading reviews on this but none have really told me what a lip oil is actually for. Cheaper brands like NYX, Elf have also brought out lip oils but again after researching im none the wiser on the actual use of these oils.
