What causes Allergic Contact Dermatitis?
Although plants and animals can cause ACD, it is commonly due to metals, chemicals in self care products or even cleaning products.
People are not born with Allergic Contact Dermatitis, they acquire this reaction over time.
Contact allergies tend to develop gradually over a long period of time, as a result of repeated contact with the substance that triggers them.
Even if you have been using a product for several years, you can become sensitised to ingredients. Moreover, manufacturers can change their formulas or use a different formula name making it difficult for you to know exactly what your skin is in contact with.
