What percentage of contact dermatitis cases are Irritant Contact Dermatitis (ICD)?
Answer
Around 80% of all contact dermatitis cases
Irritant Contact Dermatitis (ICD) represents the overwhelming majority of contact dermatitis diagnosed in clinical dermatology settings. Specifically, ICD is cited as accounting for approximately 80% of all cases encountered by dermatologists. This statistic underscores that direct chemical damage to the skin barrier is a far more frequent cause of external skin reactions than immune system-mediated allergies. ICD results from a direct assault on the stratum corneum, such as from frequent exposure to strong cleaning agents or solvents, leading to its predominance over the less frequent, immune-driven Allergic Contact Dermatitis (ACD).
