Detailed answer

High humidity can worsen facial eczema as it increases moisture in the air, leading to increased sweating and potential skin barrier disruption. This can result in skin irritation, itching, and flare-ups in individuals with eczema. On the other hand, low humidity can dehydrate the skin, making it prone to dryness, itchiness, and potential eczema flare-ups. It is important for people with facial eczema to maintain a balanced humidity level in their environment through the use of humidifiers or dehumidifiers as appropriate, and to follow a consistent skincare routine to protect and moisturize the skin.
