Both the oil and the extract can have antimicrobial properties (Source: Journal of Agricultural and Food Chemistry, July 2002, pages 3943–3946), but they can also have an irritating, sensitizing effect on skin. Peppermint oil is a more potent irritant than, say, peppermint water. Peppermint is a common cause of allergic contact dermatitis on the face, particularly around the mouth, as peppermint is used as a flavoring in countless toothpastes (Sources: International Journal of Risk and Safety in Medicine, January 2012, pages 147-161; Dermatitis , November-December 2010, pages 327-329; and www.naturaldatabase.com).
