Dry skin on the face can be caused by a variety of factors, including environmental factors, harsh soaps or skincare products, skin conditions, and aging. Some common causes of dry skin on the face include:

• Cold or dry weather
• Sun damage
• Harsh soaps and detergents
• Overbathing or showering with hot water
• Skin conditions such as eczema or psoriasis
• Medical treatments such as chemotherapy or dialysis
• Aging

To prevent and treat dry skin on the face, it is important to moisturize regularly, use gentle cleansers, and avoid over-washing or over-exfoliating the skin. Additionally, using a humidifier in dry indoor environments and protecting the skin from the sun can also help prevent dryness. If dryness persists or is accompanied by other symptoms, it is important to consult a dermatologist or healthcare professional for further evaluation and treatment.
