Detailed explanation-1: -Contact dermatitis causes redness, itching, and small blisters (vesicles). This is a close-up of a dermatitis reaction. It consists of a large, red (erythematous) lesion (plaque) with numerous small pus-filled areas (pustules). This is a typical early appearance of a poison ivy rash, located on the knee.

Detailed explanation-2: -Contact dermatitis Contact dermatitis appears hours to days after an area of skin has been in contact with an allergen or irritant. The skin becomes itchy, red, scaly, or raw. Blisters can form, which weep, ooze, or become crusty.

Detailed explanation-3: -The area is usually a pink or red color and feels itchy. Contact dermatitis may appear flat or raised, and in severe cases, blisters filled with clear fluid may result. Although some people react more quickly than others, these rashes tend to take time to develop and don’t occur with the first exposure.
