Allergic Contact Dermatitis Contagious. Contact dermatitis is a type of skin inflammation. It is the result of exposure to allergens (allergic contact dermatitis) or irritants (irritant contact dermatitis).
Phototoxic dermatitis occurs when the allergen or irritant is activated by sunlight. The diagnosis of allergic contact dermatitis can often be supported by a patch test.
Symptoms associated with allergic contact dermatitis include:
- dry, scaly, flaky skin
- oozing blisters
- skin redness
- skin that appears darkened or leathery
- skin that burns
- extreme itching
- sun sensitivity
- swelling, especially in the eyes, face, or groin areas

How is contact dermatitis treated?
Most cases of contact dermatitis go away on their own once the substance is no longer in contact with the skin. Here are some tips you can try at home:
- Avoid scratching your irritated skin. Scratching can make the irritation worse or even cause a skin infection that requires antibiotics.
- Clean your skin with mild soap and lukewarm water to remove any irritants.
- Stop using any products you think might be causing the problem.
- Apply bland petroleum jelly like Vaseline to soothe the area.
- Try using anti-itch treatments such as calamine lotion (Caladryl, Swan) or hydrocortisone cream (Cortisone-10).
- If needed, take an antihistamine drug such as diphenhydramine to cut down on itching and to reduce your allergic response.
