What should I do about small red rashes on the skin?

When red rashes appear on the skin, it is essential to first identify their possible causes, as different causes require different treatments. 1. Determine the cause: Skin rashes may be caused by various factors, including allergies, folliculitis, chickenpox, solar dermatitis, or contact dermatitis. 2. Avoid irritants: Avoid using cosmetics or skincare products that may irritate the skin; minimize scratching and friction to prevent further skin damage. 3. Medication treatment: For rashes caused by allergies, antihistamines such as loratadine tablets or cetirizine hydrochloride tablets can be used. For rashes due to folliculitis, topical medications like erythromycin ointment or fusidic acid cream may be applied. For solar dermatitis or contact dermatitis, topical treatments such as dexamethasone acetate cream or calamine lotion can be used.
