Moisturizer: Use a fragrance-free cream, and reserve ointment or petrolatum-type products for rough, cracked, or very dry spots.
Room air: Use the humidifier to reduce DSI during high-stress days. If you have a humidity gauge, many winter rooms benefit from moving out of the very dry range, for example toward about 40-50% RH when the building allows it. Reduce use if windows fog, surfaces feel damp, or condensation appears.

If you have eczema, diabetes, poor circulation, immune suppression, open cracks, bleeding, signs of infection, or persistent itching, follow your clinician's plan and seek medical advice.
