The Pierre Cardin Cracked Heel Cream is formulated with a combination of active ingredients designed to effectively target and repair dry, cracked heels. The key active ingredients in this cream include urea, glycerin, and dimethicone, each playing a specific role in the healing process. Urea, a naturally occurring compound in the skin, acts as a keratolytic agent, breaking down hardened skin cells on the surface of the heels. This helps to soften the skin, making it easier to exfoliate and promoting cell turnover for smoother, healthier heels. In addition, urea also acts as a humectant, attracting and retaining moisture in the skin to prevent further dryness. Glycerin, a powerful humectant, further enhances the moisturizing properties of the cream by drawing water from the environment into the skin. This helps to hydrate the skin, improving its elasticity and reducing the appearance of cracks and fissures. Glycerin also forms a protective barrier on the skin, preventing moisture loss and enhancing the overall effectiveness of the cream. Dimethicone, a silicone derivative, creates a barrier on the skin's surface, sealing in moisture and preventing water loss. This barrier also helps to protect the skin from environmental aggressors and further damage, allowing the other active ingredients to work more efficiently.
