Add Some Aloe Vera
The thick, gel-like juice of the aloe vera plant can take the sting and redness out of a sunburn. Aloe vera causes blood vessels to constrict. Luckily, this healing plant is available at your local nursery or even in the grocery store's floral department. Simply slit open one of the broad leaves and apply the gel directly to the burn. Apply five to six times per day for several days.
