Brief Answer: Can be due to perfume.2-7days.Antihistamine,steroi Detailed Answer: Hi Thanks for using XXXXXXX Yes this could be due to new perfume. May be allergic or chemical reaction. Usually allergic reaction / chemical reaction occur in the exposed part. Is it itching? how does the rash look like? Is there any inflammatory signs? It will be better to diagnose if you can upload the photo of the rash. Usually the rash due too allergy or chemical disappear in couple of days with avoiding re-exposure to the same chemical. But if infected or any severe tissue damage it will take more time. If due to allergic reaction you should take anti histamine drug like chlorphneramine malate and steroid like prednisolone to prevent any further problem due to allergic reaction and can apply calamine lotion over the rash. If severe rash topical steroid(like mometasone) will help you. For chemical reaction the same measures can be followed with extra protection to rash using betadine lotion and if necessary antibiotics. Better to get examined by your doctor once to confirm the diagnose and for management based on examination. Hope this information is both informative and helpful to you. Feel free to ask if any related query and I will be glad to answer them. Wish you faster recovery. Regards
