A rash can be frustrating, especially when you are unsure of the proper treatment for it. At the Dermatology and Cosmetic Laser Center in Huntington, we see many rashes that are considered allergic contact dermatitis, the result of contact with an allergen. Unlike irritant rashes, allergic contact dermatitis rashes often have a delayed development, around 12 – 72 hours after exposure, making them difficult to diagnose.
Diagnosing allergic contact dermatitis
With allergic contact dermatitis, allergy to a specific substance can occur after the first exposure or after several. The individual can even react to a substance that previously posed no issue. Some of the most common causes of allergic contact dermatitis rashes include:
- Make-up or skin care products
- Fragrances in lotions, soaps, or perfumes
- Ingredients in creams or other topical products
- Certain types of metals found in jewelry (especially nickel)
Determining the cause of your rash
Because symptoms can be the same among the difference substance, it can be difficult to distinguish the specific cause of your rash. During your examination, we will take detailed notes on your symptoms as well as asking you questions on your exposure to specific products. Some of the most common symptoms associated with allergic contact dermatitis are: hives, redness, itching, burning, blisters, red splotches, sun sensitivity, or inflammation.
Treatment for your rash
If you have a rash that persists for several days, it’s important to have it evaluated by a professional. Certain at-home remedies such as oatmeal baths can help relieve the symptoms, but in many cases topical or oral medications may also be needed to treat the allergic reaction. Once the cause of your rash is determined, avoidance can be the best way to prevent future allergic reactions. If you are in the Huntington area, call us at (631) 417-3300 to learn more.
