Dr. Jart’s Dermask Hand Hydrating and Foot Smoothing Masks are formulated to aid the blood circulation of hands and feet with a heat reaction technology embedded in the sheet mask. Designed with the popular aluminum material found in winter clothing, it helps to increase the temperature inside the mask while shielding skin from outside. The hand and foot images on the packaging bring up the image of rubbing hands together when cold, and the hint of fluorescent color and speech bubble arouse curiosity.
