“Fats and oils in cosmetics – Mother Nature versus petrochemicals?” (Kosmetische Medizin, 2008)
This interesting (technical) article by Dr. Hans Lautenschläger compares the skin repair benefits (or not) of oils and waxes of petrochemical origin to natural fats and oils.
The take-away: “Mineral oils will not help to repair a disordered skin barrier. Even if mineral oils may fill in droplike gaps in the barrier layers they cannot be absorbed like vegetable oils.”
But you already knew that, right? 😉
