And Dr. Jacob noted that to date, there have been hundreds of reports of allergic contact dermatitis to black henna tattoos, with reactions ranging from mild eczema and ulcers to last until the scars. Then, the first sign of a reaction is typically redness and itching, swelling, inflammation and blisters. And topical steroids can be used to stop the reaction, but Dr. Jacob explained that any presence or absence of scarring occurs depends on the depth and severity of inflammation.
Also, some people can become aware PPD exposure once - which means that the immune system is configured to remember the exposed chemical or chemical with a similar structure. When this happens, a person can develop PPD sensitivity to life and can cause allergic cross reaction to other compounds, including certain medications. For example, you could use some heart medications, high blood pressure and diabetes, and even some anesthetics used in topical hemorrhoid preparations or oral gels, cause allergic reactions in people allergic PPD in the past.
