The present invention is directed to a method of inhibiting CD1d activation by administering a composition containing a moiety that blocks CD1d activation. Compositions of the invention are useful for the attenuation of CD1d-restricted immune responses, including treatment of skin disorders due to hyperactive immune responses (e.g., contact hypersensitivity), for systemic administration to attenuate ongoing immune responses, and to provide hypoallergenic cosmetic products including pharmaceutical, cosmetic, and skin care compositions. Preferably, these compositions are in a form intended for topical administration.
