For oily skin, it is best to avoid heavy, greasy creams that can clog pores. For sunburn, use pure aloe vera gel or a lightweight, oil-free moisturizer to soothe the skin. A mild topical hydrocortisone 1% cream can help reduce redness and inflammation. For prickly heat, calamine lotion is highly effective as it cools the skin and absorbs excess sweat without blocking pores. Ensure all products you use are labeled 'non-comedogenic' (won't clog pores). Cool compresses can also provide immediate relief. If you develop severe blistering or a fever, please seek medical attention.
