moderately volatile essential oils enhance absorption through the skin
Essential oils with moderate volatility (0.759–1.67 mg/h/cm²), specifically chuanxiong, Cyperus, and cinnamon oils, possessed the most satisfactory penetration enhancement effectiveness, suggesting volatility is a key determinant of transdermal efficacy.
What this means for you
When certain essential oils — like cinnamon, cyperus, and chuanxiong — are applied to skin, their moderate volatility helps active compounds absorb more effectively. This means the beneficial ingredients in a topical blend are more likely to actually reach the tissues beneath the surface, rather than sitting on top of the skin.
