Detailed answer

Exposure to cold temperatures can have a positive impact on sallow skin. When exposed to cold, the blood vessels constrict, which can help to reduce redness and inflammation. Additionally, cold exposure can stimulate circulation, leading to a healthier complexion and a more radiant appearance. The cold temperatures also induce a tightening effect on the skin, making it appear firmer and more supple. However, it's important to note that excessive cold exposure can also damage the skin, so it's crucial to find a balance and protect the skin with appropriate moisturizers and protective clothing in extreme conditions.
