Sunburn prevention?
Prevention is the best remedy here, if you can. Long-term results from excessive exposure to the sun, such as skin cancer and wrinkled skin, can be avoided with proper precautions. One of the best preventatives is to use a sunscreen with an SPF of 30 that offers protection against both UVA and UVB rays. You can get as much sun sightseeing as baking at the beach, so use sunscreen whenever you are outdoors.
Use an aloe vera lotion containing a sunblock. This will cut out 90% of the burning rays and allow 75% of the tanning rays to reach the skin.
To speed healing take the following supplements for a few days after getting burned: 1,000 mg of vitamin C, 400 I.U. of vitamin E, 15 mg of beta carotene, and 1-2 tablespoons (or about 3 capsules per teaspoon) of flaxseed oil, an essential fatty acid.
