Detailed answer

Air conditioning can have a negative impact on the skin, leading to sallowness. The constant exposure to dry and cool air from the air conditioning system can strip the skin of its natural moisture, resulting in dehydration. This can make the skin look dull, tired, and lifeless, which is often described as sallow. Additionally, air conditioning can disrupt the natural barrier function of the skin, leading to increased sensitivity and irritation. To minimize the impact of air conditioning on the skin, it is important to stay hydrated by drinking plenty of water, use a moisturizer to replenish lost moisture, and consider using a humidifier to add moisture to the air.
