Theraplex products contain two crucial components: the unique Petrolatum Fraction and cyclomethicone. Cyclomethicone functions as a distribution mechanism, allowing the unique Petrolatum Fraction to deeply penetrate the skin's cracks and fissures. Once this is achieved, the cyclomethicone evaporates, leaving behind only the pure, non-greasy Petrolatum Fraction. This Petrolatum Fraction promptly facilitates the repair of the skin's barrier layer by aiding in moisture retention and initiating the healing process.
