A system for delivering moisturizing liquid to the lips of a subject includes an applicator for applying the moisturizing liquid to the lips supported by a support structure so that at least a part of applicator is deployed so as to engage a recess between the lips of subject without obstructing contact between the subject's upper and lower lips. The proximity of the applicator to the lips allows the use of simple contact-based implementations of the applicator. At the same time, disruption of speech and other normal oral movement is minimized by avoiding any obstruction to contact between the lips.
