Contact dermatitis is a condition where a red, itchy rash appears on the skin. This occurs when your skin becomes in direct contact with a material that triggers an allergic response. The rash poses no threat and is not transmissible or dangerous but instead is very uncomfortable.
This can be caused by many substances, such as soaps, cosmetics, fragrances, jewelry, and even plants.
Generally, contact dermatitis can be treated properly by knowing what causes the reaction and avoiding it. If you can avoid the trigger of the rash, then it should clear up within two (2) to four (4) weeks. You can also use home remedies to soothe your skin such as an anti-itch cream.
