For a mild skin allergy, you can apply an over-the-counter 1% hydrocortisone cream to reduce itching and inflammation, or use calamine lotion for soothing relief. If the itching is widespread, an oral antihistamine like cetirizine or loratadine can help. It is also important to wash the area with mild soap, apply a fragrance-free moisturiser, and avoid scratching to prevent infection. Most importantly, try to identify and avoid the trigger (such as specific soaps, plants, or fabrics). If your symptoms worsen, spread, or do not improve within a few days, please consult a doctor for a personalised diagnosis.
