These people have traditionally been called “stingers” since Kligman coined the term in 1977. This skin type has also been called reactive skin, hyperreactive skin, intolerant skin, or irritable skin. In the Baumann Skin Typing System, stingers are designated as having Baumann S3 sensitive skin (see Chapter 9); the “3” denotes burners and stingers rather than other types of sensitive skin that develop such as acne (S1), rosacea (S2), or contact dermatitis (S4). One patient can demonstrate one to four different types of sensitive skin. For example, many rosacea (S2) patients are also burners and stingers (S3). Although this skin type is referred to as stingers in the context of applying chemical factors such as skin care ingredients, this skin type also includes those who feel the onset of a prickling, tingling sensation, or slight pain because of physical factors such as ultraviolet radiation, heat, cold, and wind. Psychologic stress or hormonal factors such as menstruation may play a role as well. It is important to know a patient’s susceptibility to S3 sensitive skin because this may lead to noncompliance with certain medications and vehicles that cause discomfort to the patient. Finacea is an example of a rosacea medication that causes stinging in a small proportion of users. Retin A Micro contains benzyl alcohol (a derivative of benzoic acid) that can cause stinging in certain people. This chapter will discuss what is known about the mechanisms of burning and stinging, what ingredients are most likely to cause it, and how to identify a potential “stinger.”
