Real pain relief requires getting to where the pain begins - deep inside inflamed muscles and joints. Most other pain relief creams only touch the surface, masking pain by overloading dermal receptors. Xxtreme Creme's all-natural nano delivery system (liposomes made up of phospholipids) penetrates deep into sore tissue to deliver pain-relieving and cell-enhancing ingredients directly to the cells that need it the most. Phospholipids are specialized structures that contain water soluble and oil soluable ingredients and allow them to pass through the dermal and fat (lipid) layers carrying the powerful Xxtreme Creme ingredients with them. This unique, patented delivery system gives Xxtreme Creme both a faster and longer-lasting effect by repairing deeper layers of tissue to reduce inflammation and relieve pain.
