To treat your active sunburn, apply cool compresses and generic 100% aloe vera gel to soothe the skin. For inflammation and itching, you can apply a mild over-the-counter 1% hydrocortisone cream twice daily. Avoid petroleum-based ointments as they trap heat. To protect your healing skin, use a broad-spectrum, mineral-based sunscreen containing zinc oxide or titanium dioxide with an SPF of 30 or higher, as these are gentler on irritated skin. Additionally, wear a wide-brimmed hat when outdoors, stay well-hydrated, and avoid further sun exposure until your skin has fully recovered.
