Is salt water good for a sunburn blister?

Salt water can be soothing for some skin irritations, but it's generally not recommended for treating sunburn blisters. The salt can be irritating and may worsen the blistering or lead to further dehydration of the skin. Instead, it's better to keep the affected area clean and moisturized, using cool compresses or aloe vera for relief. If blisters are severe or painful, consulting a healthcare professional is advisable.
