EWG Rating [ 1 ]
Bad for dry skin
Bad for dry skin

Alcohol Denatured is a great bacteria killer. Manufacturers often put it inside products to increase their shelf life.

It’s one of the most harmful alcohols used in skincare. You should use it carefully, especially if you have dry skin. It removes oily barrier from the surface of your skin making it less protected and causing dryness. We advise you to pay attention to the position of this component in a formulation. If it stays below the 6th position it will hardly harm your skin. We also recommend testing the product first before application. If you feel a “cooling effect” it means the product contains a lot of alcohol and it's better to be careful with it.
