In skincare formulations ethanol, isopropyl, methanol and denatured alcohol work great at making creams lighter, preserving formulas and helping other ingredients penetrate deeper.  The downside is they cause dryness, irritation and breakouts.  Look for formulas that contain plant based alcohols like Cetearyl, Stearyl, Cetyl and Behenyl alcohol.  These alcohols protect your skin and help to keep moisture in.
