Yes, this foot mask is designed for exactly that purpose. The combination of a high 10% urea concentration and the sock's occlusive format is what makes it effective for dry, thickened skin. Urea is a key part of the skin's own natural moisturizing system and works in two ways at this concentration: it helps bind water into the upper skin layers, and it gradually breaks down the bonds between hardened surface cells (keratinocytes). This process, called keratolysis, helps lift and soften rough patches, making them feel smoother and more flexible over time.
The glycerin and sodium hyaluronate act as humectants to draw and hold moisture, while the shea butter, paraffin, petrolatum and dimethicone create a protective film that significantly reduces water loss, prolonging the softening effect. This makes the mask a practical option for targeting specific problem areas like heels and calluses, especially when a regular foot cream applied in a thin layer isn't providing enough relief. For best results, it's intended as an occasional intensive step, perhaps once or twice a week, followed by daily use of a good foot cream to help maintain the smoother feel.
