Masks by My Beauty Diary. Details:My Beauty Diary hyaluronic acid moisturizing mask provides some much-needed hydration to dry skin, leaving it soft for hours. But it doesn’t brighten skin much, and is not suitable for sensitive skin. Classic and popular moisturizing ingredient, hyaluronic acid, is treated to a hi-techhydrolysis process to further reduce the size of their elements. The elements of hyaluronic acid are tiny after undergoing hi-tech hydrolysis process and these treated hyaluronic acid elements offer excellent moisturization to skin. This substance is able to quickly enhance skin by facilitating microcirculation, purification and moisturization of dry skin. Thus, the moisture content of the skin is maximized, forming a protective transparent water molecule screen, securing moisture in the skin.
