Menthol is an organic compound that can be derived either synthetically or naturally from the oils of corn mint, peppermint, or other mints.
Menthol can chemically trigger the cold-sensitive TRPM8 receptors in the skin and provoke a cooling sensation once ingested, inhaled, or applied topically to the skin.
In skincare products, menthol is mainly used for its cooling, pain relief, and scent properties.
Menthol has the ability to block the calcium current along the nerves that are responsible for detecting temperatures. The nerve endings translate a message to the brain that the skin is cooling and create a cooling effect. The cooling sensation makes menthol a key ingredient in after-sun products like lotions, gels, and creams for ultimate skin relief. Menthol helps to reduce the hot and painful sensation triggered by overexposure to the sun.
Menthol can also be used as a topical analgesic or pain reliever in some skincare products. It is often added to different cleansers or face washes designed for acne or after-sun care routines. The relief effect is achieved due to a cooling sensation.
Besides cooling and pain relief effects, menthol is added as a fragrance for its minty smell.
Individuals who have Camphor or Menthol allergy should avoid using products with menthol. For individuals who are not allergic to it, the active ingredient of menthol does not have major side effects and is safe to use on daily basis.
