OILS
FACT: Facial oils with high linoleic acid (omega-6) content are vital for managing oily and congestion-prone complexions. Unlike heavy oils, they mimic natural sebum, regulate oil production, and absorb deeply without clogging pores. In contrast, oleic acid oils (like avocado) are best saved for treating dry, mature skin.
Ingredient Penetration: Plant oils are not just barriers; they act as skin penetration enhancers. Because the stratum corneum is naturally hydrophobic, applying specific facial oils after water-based serums can assist the deeper delivery of active ingredients.
