Myths vs facts: CRP Entzündung and Haut

CRP (C-reactive protein) is a non-specific acute-phase marker of systemic inflammation. Myth: Elevated CRP directly indicates a skin disease, or normal CRP rules out skin inflammation. Fact: Many skin conditions (acne, eczema, psoriasis) are local and may not raise CRP. Only severe cases or systemic involvement (e.g., psoriatic arthritis) can cause moderate CRP elevation. CRP is also influenced by infection, injury, or stress. Consumer tests (e.g., MyBody-X) provide a single value without clinical context, which can be misleading. Evidence for a direct CRP–skin link is mostly mechanistic/observational. CRP testing should not replace a dermatologist's evaluation. Safety note: Do not self-diagnose or self-treat based on CRP results.
