Rubefacient

Substance for topical application that produces redness of the skin

A rubefacient is a substance for topical application that produces redness of the skin, e.g. by causing dilation of the capillaries and an increase in blood circulation. It has sometimes been used to relieve acute or chronic pain, but there is limited evidence as to its efficacy, and as of 2014 the best evidence does not support using gels and creams containing rubefacients for this purpose.
