1. Urea "Keratin-Softening Bomb," Gentle Bulldozer for Calluses and Cracks: Containing a high concentration of 20%-40% urea, it acts like a "miniature chemical engineer," precisely penetrating the stratum corneum to break down stubborn calluses and hardened skin layer by layer, while dry, cracked skin absorbs moisture. Apply a thick layer before bed, and dead skin will automatically peel off in the morning, transforming heels from "cracked tree bark" to "soft tofu," even brightening dull joints—the effect is comparable to a professional foot massage. 2. Ceramide "Moisture-Locking Protective Clothing," 24-Hour Hydration Without Dryness: A combination of ceramides and glycerin builds an "invisible dam" on the skin's surface, firmly locking in moisture. The texture is as soft and creamy as a "cloud kiss," yet non-sticky, absorbing quickly after application. It leaves skin feeling neither oily nor sticky even after wearing socks, maintaining a "just-done-spa" hydrated feeling for 24 hours, avoiding the embarrassment of "the more you apply, the drier it gets." 3. A convenient "foot care magic wand," a lazy person's dream, suitable for both day and night: The gel stick design is like a "portable massage pen," no need to dig with your hands or get your nails dirty, just apply directly to dry and cracked areas. Apply a thicker layer at night and use cotton socks for a "sealing therapy" effect, while applying a thinner layer during the day acts as an "invisible protective layer," effectively addressing dryness in heels, elbows, knees, and other hard-to-reach areas. Compact and portable like a "pocket first aid station," it's perfect for giving your feet a "treat" anytime, anywhere, making it incredibly cost-effective.
