Disclosed are skin immune function controlling agents which contain as the active ingredient a volatile substance capable of stimulating the olfactory receptor, as typified by a specific perfume. By controlling the skin immune function, these agents serve, for example, to enhance the skin barrier function and to prevent or treat skin contact hypersensitivity.
