Detailed answer

Low humidity can have a negative impact on sallow skin. When the humidity levels are low, the air becomes dry and can cause the skin to lose moisture. This can lead to dehydration and make the skin appear dull and sallow. Additionally, low humidity can interfere with the skin's natural barrier function, making it more prone to irritation and inflammation. To combat the effects of low humidity on sallow skin, it is important to keep the skin hydrated by using a moisturizer and drinking plenty of water. Using a humidifier in dry environments can also help to increase the moisture levels in the air and alleviate the sallowness of the skin.
