Most cosmetic moisturizers only provide short term relief of persistent dry skin, using various ingredients to provide the sensation of moisture. When applied to the skin, Theraplex immediately helps the skin's barrier to retain moisture and significantly reduces moisture loss for up to 8 hours. The special petrolatum fraction forms a greaseless, durable micro-protective layer. Theraplex utilizes an activated hydrosilicone delivery system which enables the special petrolatum fraction to quickly penetrate deep into the cracks and fissures of the skin where moisture is needed most. Studies have shown that Theraplex stops and prevents the vicious cycle of persistent dry skin resulting in softer, smoother, well-hydrated, healthier-looking skin.
