Can I use this cream on areas other than hands, such as elbows, knees, or cuticles?

The product description explicitly mentions hands and around the nails as primary application areas, and adds "other dry areas that need extra softness." This is typical for richer nourishing creams: the same lipid-replenishing ingredients (vitamin F for the lipid layer, mineral salts for moisture balance, vitamins A and E for smoothing and antioxidant protection) benefit any thickened or chronically dry skin — elbows, knees, heels, and cuticles included.

For cuticles, massage a small amount into the nail base and surrounding skin after washing hands or before bed; the emollient base helps keep the cuticle pliable, reducing hangnails. For elbows or knees, apply to clean, slightly damp skin (after a shower is ideal) to lock in maximum moisture. Because the texture is richer than a body lotion, you only need a pea-sized amount per area. Avoid applying to broken, freshly irritated, or post-procedure skin — the source advises a patch test first if your skin is very reactive.
