Detailed answer

Dry air can worsen sallow skin, making it appear dull and lackluster. When the air lacks moisture, it can further dehydrate the skin, making it more prone to dryness and flakiness. This can accentuate the appearance of sallowness, a yellow or dull complexion. In addition, dry air can reduce the skin's natural ability to exfoliate dead skin cells, leading to a buildup on the surface and contributing to a sallow appearance. Therefore, it is important to maintain proper skin hydration and moisturization, especially in dry air conditions, to help minimize the impact on sallow skin.
