Now, this might sound like one of your English professors answering the question of “how long should the essay be” but the simple answer to this is “enough to cover your exposed body”. According to the American Academy of Dermatology, a general rule of thumb is that most adults need to apply about the equivalent of a shot glass (1 Ounce or 2 Tablespoons) of liquid sunscreen to the exposed areas of the body and face.
There are many forms of application for sunscreen, so this is not a one size fits all practice. For spray-on sunscreens make sure you are using enough to have an even sheen of sunscreen across bare skin. There are also sunscreen sticks to be used for sensitive skin, as well as clear gels. Regardless of the formula that you are using make sure you are fully covered from the sun’s rays.
An important practice to remember when spending time outdoors is to make sure you are re-applying this amount of sunscreen at least every two hours, or more frequently if you are in the water. The FDA recommends that you are using a broad-spectrum sunscreen of SPF 15 or higher or SPF 30+ if you are spending extended time outdoors. The broad-spectrum will make sure you are protected against harmful UVA & UVB rays.
The best sunscreen is a sunscreen that you use daily. There are many forms of sunscreen made available to the consumers for preferences and ease of use, but the best one is one that you use consistently and effectively.
