Theraplex Ultra combines superior moisturization and barrier protection in a virtually greaseless, elegant formula. Persistent dryness is caused by constant moisture loss from the skin's vital outer layers, the stratum corneum and the epidermis beneath, which results in rough, dry, cracked and fissured skin. The long-term solution to dry skin lies in the ability of essential moisture to penetrate deep into the dry cracks and fissures of the skin, sealing them and allowing the skin to retain its natural, internal moisture. The result is softer, smoother and healthier-looking skin. This unique formulation contains a Special Petrolatum Fraction, a patented system developed to eliminate over 82% of the greasiness associated with petrolatum products.
