Skin diseases can be caused by a variety of factors, including infections (bacterial, viral, or fungal), allergies, autoimmune reactions, parasites, and cancers.
For example, a bacterial infection can lead to conditions like acne, while a viral infection can cause cold sores. Allergies can trigger eczema or hives, and autoimmune reactions can cause psoriasis. Parasitic infections can lead to scabies or ringworm, and skin cancer can develop from unprotected sun exposure or genetic predisposition.
In addition to these common causes, environmental factors like exposure to irritants or chemicals can also contribute to skin diseases.
Conditions that affect the thyroid, kidneys, or immune system can also manifest in the skin.
It's important to remember that most skin diseases are not contagious, and there are often effective treatments available.
