What skin conditions is this 40% urea cream actually meant for? I see it's for dry skin, but how is it different from a regular hand cream?

This cream is designed for a specific type of dryness: very dry, roughened skin that has become thick, hard, and tends to flake or develop cracks. Ordinary moisturizers work on general dryness, but they often cannot address the buildup of excess keratin—the tough protein that forms calluses on heels, rough patches on palms, elbows, or knees. The 40% urea works by softening this hardened surface layer, helping to loosen the bonds between dead skin cells so they can shed more naturally, making the skin smoother and more flexible. This makes it a targeted rescue product, best for areas where the skin feels tight, coarse, or is prone to splitting, rather than a light lotion for all-over daily use.
