ABSTRACT
The development of consumer health and beauty products routinely includes intensive premarket product testing intended to ensure that any marketed product is free of irritant potential. It is, nonetheless, not uncommon for postmarketing surveillance personnel to receive reports of unpleasant sensory reactions to such products not predicted by even the most robust development methodology (1). These sensory perceptions, often transient and unaccompanied by neither classical visible signs of irritation nor any immunologic response, have become a dermatologic phenomenon now most commonly known as sensitive skin.
