Among sensitive skin individuals, there is a subgroup known as stingers, so named because in response to chemical irritants, they experience unusually strong sensations of stinging and burning. Beyond subjective sensory responses to irritants, some stingers also exhibit greater erythematous (objective) responses to irritant exposure.

Early research in 1977 on this subject found that stingers had heightened susceptibility to general irritation.21 However, more recent studies22,23 found no evidence that strong reactivity to one nonimmunological irritant was predictive of such a response to other irritants.22
