How does the cooling sensation actually work — is my skin temperature really dropping?

The cooling effect comes from menthol and camphor interacting with sensory receptors in the skin, not from an actual temperature drop. Menthol binds to TRPM8 receptors — the same ones that respond to cold temperatures — so your brain registers a distinct cool feeling even though a thermometer would show little change. Camphor adds a mild stimulating sensation first, then blends into the menthol's cooling impression. This is why the relief feels immediate but is sensory rather than thermal. The gel base helps deliver these ingredients evenly and lets them evaporate slightly during massage, which can enhance the fresh perception. It's a cosmetic sensory effect, not a physiological cooling of tissues.
