Hi, After reading your query the closest possibility of your problem appears to be allergic dermatitis after eye brow threading. This is a condition caused by bursting of allergy producing cells known as mast cells due to threading. As the chemical inside them is released causes the kind of rash which you mentioned. Kindly follow the suggestions below: -Apply fluticasone cream 2 times a day. -You can do cold water compresses to reduce the intensity of itching. -Do not scratch or rub the skin as it can lead to further aggravation. You can take oral anti histamine like loratadine or levocetrizine under medial advise. Despite above measures if the problem is not getting better then it is better to consult a dermatologist for best guidance. Take care.
