To treat sunburn, apply a cold compress to the affected areas, apply a cooling gel or aftersun lotion, and avoid sun exposure until the discomfort resolves.

Excerpt: For mild sunburn, apply a moisturising lotion or aftersun cream, available at pharmacies. Aftersun cream will cool your skin and moisturise it, helping to relieve the feeling of tightness. Moisturisers that contain aloe vera will also help to soothe your skin. Calamine lotion can relieve any itching or soreness.
