How Does Sunburn Affect the Skin?

Sunburn affects the skin by damaging the cells in the outermost layer (epidermis). The severity is classified into degrees:

  • First-degree: Redness, pain, and tenderness that lasts a few days.
  • Second-degree: Severe redness, swelling, and blistering, which may take weeks to heal and require medical attention. This damage can peel, representing the body shedding the damaged cells.

Is Sunburn a Serious Condition?

Yes, severe sunburn is serious and requires medical care. Beyond the immediate pain and dehydration, repeated episodes of sunburn, especially during childhood, dramatically increase the lifetime risk of developing all types of skin cancer, including the deadliest form, melanoma.

Do I Need a Prescription to Treat Sunburn?

Most first-degree sunburns can be treated with over-the-counter (OTC) pain relievers, cooling gels, and moisturizing creams. However, second-degree burns with severe blistering, signs of infection, fever, or signs of dehydration require immediate medical attention and may necessitate prescription burn creams or pain medication.

What Should I Do to Manage or Care for Sunburn?

Care focuses on reducing inflammation and preventing infection:

  • Cooling: Take a cool bath or apply cold compresses to the affected areas.
  • Moisturizing: Apply aloe vera or a gentle moisturizing cream to soothe the skin and reduce dryness.
  • Hydration: Drink plenty of water to prevent dehydration. Do not pop blisters as they protect the underlying healing skin.
