Question: What causes sun rash/poisoning?
Some people tan, some people burn, and unfortunately, some people develop rashes after being in the sun. The rash, also commonly known as sun poisoning, can be caused by a hereditary sun allergy, a reaction due to use of certain medications, such as retinoid, or even exposure to plants.
In addition to wearing sunscreen, the best ways to avoid developing a sun rash is to limit your sun exposure and keep covered up. Protect you face with a wide brimmed hat and wear sun-protective clothing. Keeping well hydrated while you are out in the sun will also help.
