Introduction
After sunburn causes white blisters on the skin, manage it by cooling and soothing the area with cold compresses, protecting the blisters from breaking, avoiding further irritation or injury, performing gentle local care, and replenishing fluids and nutrients to prevent infection and worsening damage. If the blisters become numerous and spread, if pain is severe, or if fever, redness, and swelling occur, seek medical attention promptly. Wrap an ice pack or a cloth soaked in cold water with a clean towel and apply it as a cold compress to the affected skin.
After sunburn, if white blisters appear on the skin, it is important to manage them by cooling and soothing with cold compresses, protecting the blisters' integrity, avoiding irritation or injury, performing gentle local care, and replenishing water and nutrients to prevent infection and further damage. If the blisters become numerous and spread, are accompanied by severe pain, or signs such as fever, redness, and swelling occur, prompt medical attention is recommended.
1. Cooling and Soothing with Cold Compress: Wrap an ice pack or a piece of gauze soaked in cold water with a clean towel and apply it to the blistered area for 15–20 minutes at a time. This helps lower skin temperature, relieve burning and pain, and reduce fluid leakage from tissues.
2. Protecting Blister Integrity: Do not puncture blisters intentionally, as the overlying skin acts as a natural barrier to protect the wound and prevent infection. If a blister breaks accidentally, gently wipe away any exudate using a clean cotton swab and keep the area clean.
3. Avoiding Irritation and Injury: Avoid rubbing or scratching the blistered area. Wear loose, breathable cotton clothing to minimize friction and prevent further sun exposure, reducing irritation to damaged skin.
4. Gentle Local Care: Apply a mild, alcohol-free, fragrance-free moisturizing repair cream or aloe vera gel to keep the skin hydrated and support epidermal healing. Avoid using irritating ointments or cosmetics.
5. Replenishing Water and Nutrients: Drink plenty of water to rehydrate the body and consume foods rich in vitamin C and vitamin E to aid in repairing damaged skin cells and strengthening skin resistance.
When going outdoors, apply sufficient sunscreen in advance and use protective gear such as sun hats and sun-protective clothing. Avoid prolonged exposure to intense sunlight. After sunburn, avoid washing the affected area with hot water. Keep the skin clean and dry to promote wound healing.
