How exactly do I use it for best results on very rough heels or hands?

For the most noticeable effect on rough areas like heels or palms, apply the cream to clean skin, ideally while it's still slightly warm and damp after bathing or washing. This helps the skin absorb moisture more effectively. Use a generous amount, but only on the specific areas that need it—the thickened heels, calluses, rough palms, or elbows. Gently massage it in. For intensive treatment, especially on heels, applying a thick layer before bed and wearing cotton socks overnight can help keep the cream in contact with the skin and enhance the softening effect. For ongoing maintenance, you might use it daily until the skin improves, then switch to a few times a week as needed. Avoid applying to broken skin or sensitive zones unless you are sure your skin tolerates it well. If you experience any irritation, discontinue use.
