Alcohols such as ethanol, ethyl Nulavance Reviewalcohol, methanol, benzyl alcohol, isopropyl alcohol and SD alcohol are used in many products and actually dry your skin and irritate it. Clearly the opposite of what you would want in your moisturizer.
Another common ingredient in skincare products is mineral oil. Although it sounds innocuous, mineral oil is a derivative of petroleum and not only dries your skin over time, but can clog your pores and cause other problems such as acne flare-ups. What's more, mineral oil has been linked to cancer in laboratory tests on mice!
Clearly alcohol and mineral oil are not substances you would want when looking for today's best day moisturizer.
