Alcohol
Rating: Average
In skincare, alcohol serves various functions but can be a bit controversial. Commonly used types, like ethanol or isopropyl alcohol, act as quick-drying agents, giving products a lightweight feel and helping to dissolve ingredients for better absorption. However, they can sometimes strip natural oils and dry out the skin, especially in higher concentrations, which may lead to irritation for sensitive skin.
On the other hand, fatty alcohols (like cetyl, stearyl, or cetearyl alcohol) are skin-friendly and often used to thicken and stabilize formulations. These types of alcohols are emollient, meaning they help soften and smooth the skin, and are well-tolerated by most skin types.
