Eczema is a complex condition leading to skin inflammation, stemming from a combination of both environmental and genetic factors. Key triggers include exposure to irritating chemicals such as soap, detergent, and shampoo, as well as environmental allergens like cold and dry air, excessive humidity, dust, pollen, and mold. Internal factors such as genetic predisposition, stress, anxiety, and a weakened immune system also play a significant role. Bacteria like Staphylococcus aureus can disrupt the natural skin microbiome, weakening the skin barrier function and potentially accelerating the development of eczema. Furthermore, elements such as makeup and skincare products, perfumes, food allergies, certain metals, and air pollution can also exacerbate or trigger symptoms.
