Ethanol is a simple alcohol commonly used as a solvent, antiseptic, and penetration enhancer in cosmetic formulations. It helps dissolve other ingredients, can provide a quick-drying finish, and has antimicrobial properties. While effective, high concentrations can be drying or irritating to the skin.

Retinoid— High concentrations of ethanol can increase irritation and dryness when used with retinoids, which are already potent and can cause sensitivity.

Not necessarily. While high concentrations can be drying and irritating, alcohol can serve useful functions like improving ingredient penetration or providing a lightweight feel. Its impact depends on the concentration and overall formulation.
Does alcohol dry out the skin?
Yes, in higher concentrations, alcohol can strip the skin's natural oils, leading to dryness and potential disruption of the skin barrier. Formulations with lower concentrations or combined with emollients may mitigate this effect.
