What to do about dry skin when using air conditioning

Maintain indoor humidity between 40% and 60% when using air conditioning to reduce skin moisture loss. Regularly open windows for ventilation to keep the air fresh. Choose skincare products containing natural moisturizing ingredients, and avoid using strongly alkaline cleansers. Drink plenty of water to replenish body fluids. Place a humidifier or a basin of water in air-conditioned rooms to increase indoor humidity. If skin dryness is severe, seek medical advice promptly for professional treatment.
