For a normal sunburn, the After Sun is your perfect choice with over 150% concentration of Emerald Aloe.  For a more severe sunburn try Andra Sina Rescue or Relief Ointment with a concentration of Emerald Aloe over 300%.
Remember, the sooner you apply a generous amount of Emerald Aloe on your skin, and the more often you apply it, the better your results.  The Clinical Studies showed a major difference in diminishing skin damage within 30 minutes of application.
