Manage the circadian rhythm and look marvellous at any second! Circadian rhythm is the function of any body cell including skin cells. Throughout the centuries this rhythm is set by the natural alternation of day and night. Stresses, irregular sleep patterns, dynamic lifestyle and even the constant contact with gadgets interfere with this biological clock, and it disrupts circadian cycles in your skin. The skin shows signs of fatigue, becomes stressed and irritation-prone. Harmony Sleep Night Mask formulated with the B-Circadin complexTM and vulcanic thermal water is designed to regulate circadian rhythms. • B-CircadinTM  regulates skin cell renewal in accordance with the time of day helping the cells restore more efficiently every day. • Vulcanic thermal water deep from the ancient French Auvergne volcanos infuses skin with valuable elements and minerals.
