Menthol is used for controlling itchiness or irritation of the skin. Applied topically, it has the ability to reduce the need to scratch, especially during common rashes or outbreaks. It is a great way to cool the surface of the skin and allow inflammation to disperse quicker. Menthol penetrates through the pores and the epidermis/dermis of the skin and provides a cool and calming feeling on the irritated surface of your skin.
