Rashes can take many different forms, and the most common causes include contact dermatitis, body infections, and allergic responses to medications. They can be dry, wet, lumpy, smooth, cracked, or blistering, and they might be uncomfortable, itchy, or change color. The skin's outer layer can be damaged by chemicals, pollution, sunlight, heat, trauma, etc., so keeping yourself safe is important. When you go out into the world, you need to use some caution to protect yourself from its dangers. Contact dermatitis develops when your skin comes in contact with something that irritates or burns it. This may be because of a chemical in the item, for example, if you get burned trying to clean a stove, your skin will come in contact with chemicals on the stove that cause an allergic reaction. You will then have to avoid these items to prevent this from happening again. A body infection causes sores to form on the skin, usually due to a problem with the immune system or bacteria affecting the skin. These infections can be caused by viruses, fungi, or parasites. Body rashes often look similar to skin disorders such as eczema or psoriasis. It is important to identify the type of organism causing the infection, as this will determine the best treatment method. Medication allergies are one of the most common causes of skin rashes.
