Unfortunately, without regulation or an at-home testing lab, you can’t be sure. The ingredient list could offer some clues, said Dr. Anne Chapas, a dermatologist in New York City and a fellow of the American Academy of Dermatology. Aloe vera should be listed as one of the first three items, she said, suggesting it’s one of the most important components.
Searching for Latin names, such as Aloe vera or Aloe barbadensis, on the list can also help verify that an aloe product is genuine, said Dr. Grundmann. Just avoid products that say they contain Aloe ferox, another plant species that is smaller, faster growing and cheaper to use than aloe, but less well studied, has different medicinal properties and doesn’t work for sunburn.
Some, but not all, products may list active ingredient concentrations. dr. Grundmann suggested looking for a 95 percent pure aloe vera gel, although Dr. Ferris warned not to put too much faith in percentages listed on labels.
“There are many products that say 100 percent, but the wording can be deceiving,” she said. “Some say 100 percent aloe, but also contain other ingredients, which means they are not 100 percent aloe. Others say 100 percent gel, but not 100 percent of what is in that gel is aloe.” Because of this lack of standardization in concentrations, she said, it’s hard to recommend a specific percentage to watch out for.
That said, buying a bottle of aloe probably won’t break the bank. You can buy a 16-ounce bottle of aloe vera gel at Target for about $6.
What other methods can I use to relieve sunburn?
Frequent cool baths or showers can help relieve the discomfort of a sunburn, according to the American Academy of Dermatology. Applying a heavy, emollient moisturizer can protect and hydrate the skin, said Dr. chapas. Drinking extra water can also help prevent dehydration, and pain relievers such as aspirin or ibuprofen can reduce swelling, redness, or discomfort.
Short-term use of corticosteroid creams can also provide relief for itchy, inflamed skin, said Dr. Grundmann. (Keeping the cream in the refrigerator can have a cooling effect, he added.) And always make sure to protect sunburned skin from further sun exposure while it heals.
