Systemic Contact Dermatitis

Systemic contact dermatitis is a skin condition that occurs when a person who is allergic to a substance is exposed to it, leading to an immune system reaction not just at the contact site, but throughout the body. This can happen when allergens enter the bloodstream, possibly through the skin, or by ingestion. Symptoms include red, itchy, and inflamed skin that can appear in areas far from where the exposure happened. Identifying and avoiding the offending substance is key to prevention and management of the condition.
