Say it with me: To win the war against oily skin, you must fight oil with oil.
"Traditionally, we fight oily skin by stripping it of its essential oils," explains Emer. Unfortunately, this action tricks the skin into thinking it is dehydrated and results in the production of more sebum resulting in all that greasiness you were hoping to avoid from the start.
"When you apply oil formulated specially for the face, the skin believes it is hydrated and sebum production remains under control."
His favorite oil of the moment: Restorsea 24kt Liquid Gold Face Oil with Vibransea Complex ($150).
