Aloe is a flowering succulent plant which is common in Africa. It was used since Ancient times as a skin lotion because of its vulnerary (promotes wound healing) and emollient (topically soothes and soften external tissues) properties. This makes Aloe especially useful in healing the skin. It also has a cooling sensation when it is applied, which no doubt relieves the warm and red sunburned skin.
If you have an aloe plant at home, simply split the aloe leaf in half and the clear gel inside can be applied to the skin. Otherwise, purchasing an organic aloe vera gel from your local health food store can be beneficial to have on hand during your trip to the beach or while on vacation. Apply it as soon as you are out of the sun and notice the reddened skin. Re-apply as needed! The sooner you treat your skin to aloe, the faster it can begin to re-hydrate and soften without too much discomfort.
While I strongly encourage the use of sunscreen while you are out enjoying the sun, use this sunburn first aid tip for you and your family!
