Dehydrated skin is a lack of moisture (water) in the skin. The principal causes of dehydrated skin include prolonged exposure to sun, heat or wind, harsh skincare products (soap-based cleansers), not drinking enough water, excess caffeine, and certain medications. Hydraphase provides targeted, long-lasting hydration to dehydrated skin types. This line rehydrates, protects, soothes, cools and refreshes and can be used on sensitive skin types. The three main ingredients to this line include Time-Released Polymer to trap water in the skin and release it throughout the day, Glycerin to absorb water from the air and deliver it to the skin and Thermal Spring Water to soothe, calm and strengthen the skin.
