Dead Sea Minerals are believed to stimulate and enhance natural blood circulation, encourage regeneration of the skin cells thus improving the quality and elasticity of the skin. They have also been found in studies to improve skin conditions such as acne, psoriasis, eczema, rosacea and boasts anti-aging properties.
According to a study performed by the University of Kiel in Germany, the minerals in Dead Sea Salt "are known to bind water, influence epidermal proliferation and differentiation, and enhance permeability barrier repair," which means that they help the skin retain water and keep it moisturised. Research indicates moisture in the skin can lead to a REDUCTION IN THE APPEARANCE OF WRINKLES and the prevention of new wrinkle formation.
Dead Sea salts work in contrast to artificial moisturisers which replace your skin’s moisture with artificial moisture, the salt in Dead Sea Minerals penetrates deeply into the skin and enhances retention of moisture.
