3. Usage Alcohol:

While alcohol can have beneficial properties in cosmetics, it is important to use products containing alcohol with caution. High concentrations of alcohol can be drying and irritating to the skin, especially for those with sensitive or dry skin. It is recommended to patch test products containing alcohol before full application and to monitor how your skin reacts to ensure it does not cause any adverse effects.
