Contact dermatitis is a skin inflammation that occurs when the skin comes into direct contact with an irritant or allergen. It typically causes red, itchy, and sometimes blistered or cracked skin. The condition can affect any part of the body but is most common on the hands, face, neck, or areas exposed to chemicals, soaps, metals, or cosmetics.

Symptoms typically appear within hours to a few days after exposure:

Rash – Redness and inflammation in exposed areas.

Irritation & Itching – Burning, stinging, or persistent itching sensation.

Blisters or Dry Patches – Crusting, scaling, or oozing in severe cases.

Repetitive Flare-ups – Recurring rash when re-exposed to the allergen or irritant.

Individuals with sensitive skin, frequent exposure to soaps, chemicals, cosmetics, gloves, or metals (e.g., nickel) are more prone to developing contact dermatitis. Healthcare workers, beauticians, and cleaning staff are especially at risk.
