What is the effect of peppermint oil when used on the skin?

Peppermint oil is known for its distinct cooling effect when applied to the skin. This sensation is largely due to the presence of menthol, a compound found in peppermint, which activates the cold-sensitive receptors in the skin. When used in skin care, peppermint oil can provide a refreshing and invigorating feeling, making it particularly popular in products designed for conditions like muscle soreness or fatigue.

The cooling properties of peppermint oil can also help reduce the perception of itchiness or irritation, offering temporary relief. This effect is why peppermint oil is often included in formulations aimed at providing a sense of refreshment, especially in warmer climates or during physical activity. The other options, while relevant to various skincare ingredients, do not accurately represent the primary effect of peppermint oil on the skin.
