Your skin is your largest organ, and it is the most exposed to the outside world. So you must take extra care to take care of it.
If you burn easily in the sun, and you are planning to spend any significant amount of time in the sun, make sure to get strong sunscreen, and apply it to all exposed areas. Remember, sunscreen is a shield, so you must take care to cover every inch.
If you do get sunburned, apply aloe vera to the affected areas.
