Detailed answer

Environmental factors such as low humidity, cold weather, wind, and exposure to harsh chemicals can have a negative effect on dry skin. These factors can lead to increased water loss from the skin's surface, resulting in dryness, tightness, flakiness, and itchiness. Low humidity levels in the environment can cause the skin to lose moisture more rapidly, aggravating dryness. Cold weather and strong winds can further strip the skin of its natural oils and disrupt its barrier function, making it more prone to dryness. Additionally, exposure to harsh chemicals in cleaning products, detergents, and certain skincare products can irritate and dehydrate the skin, exacerbating dryness. It is important to protect and moisturize the skin adequately, especially in dry and challenging environments, to maintain its hydration and barrier function.
