Risk Factors and Epidemiology
When it comes to allergic contact dermatitis, everyone is at risk, although the specific substances they may react to can vary based on individual sensitivities. However, there are certain populations that are more prone to developing irritant contact dermatitis. These include women, infants, older adults, and individuals with a history of atopic dermatitis. The higher rate of irritant contact dermatitis in females is believed to be attributed to their more frequent use of jewelry and fragrances.
Furthermore, individuals with occupations that involve regular exposure to chemicals face a significantly higher occupational risk of developing irritant contact dermatitis. In general, contact dermatitis is most commonly found in people with fair skin and red hair.
Symptoms of Contact Dermatitis
Contact dermatitis can present with similar symptoms regardless of whether it is irritant or allergic in nature. Initially, individuals may notice swelling, tenderness, oozing blisters, and dryness at the affected area. Additionally, itching, burning, stinging, pain, or soreness may also be experienced. As the condition progresses, the rash may worsen and develop scales, crusts, and hyperpigmentation. In cases of chronic contact dermatitis, the skin may undergo lichenification, which is characterized by thickening and leathery texture along with exaggerated cracks, wrinkles, and scales.
