Does mineral oil applied to skin prevent other ingredients applied on top of it from reaching skin?
I'm a bit confused about mineral oil. Is it absorbed into the skin at all or does it just sit on top of the skin forming a layer?
My favourite moisturiser is mineral oil based and I use physical sunscreen on top of it which contains some good stuff for skin eg antioxidants etc.
So does the mineral oil in my moisturiser prevent ingredients in my sunscreen from reaching my skin?
