FRESHNESS SOLUTION - Sea Crystals (Eucalyptus & Wintergreen) are foot soaking salts. They are especially suitable for tired feet, which sweat a lot or not enough! These are the salts that we use most frequently. Our Crystals contain all the essential elements required for the proper functioning and health of the skin. They are also enriched with other elements that are easily absorbed by the skin during baths and they quickly pass through the body's circulatory system.
