SPF 50
SPF 50 is one of the highest SPF ratings you can find. In order for any sun care product to be effective, it must be labeled with an SPF rating. This term is short for sun protection factor and can be found on virtually every label of sunscreen and sunblock.
The SPF rating of a sun care product is represented by a number and indicates how much longer you can stay out in the sun before your skin begins to burn. Most people pick a sunscreen with SPF 15, which works for those who don't tend to burn as easily. Those with fair-skinned complexions as well as others that tend to burn quickly often need a sunscreen with an SPF of 30 or higher. The higher the SPF rating, the more protection against ultraviolet rays is offered. To test the SPF rating on a product, it is applied to the skin and then timed to figure out how long it takes for sunburn to occur after the first application.
Because some sun care products use misleading claims such as all day protection, and long lasting power, the SPF rating system was reinforced by the Food and Drug Administration in the United States, and similar organizations in other countries also followed suit to make sure consumers were properly protected and educated about the items they were purchasing for themselves and their families. To make things easier, many sun care products that offer a lot of protection are generally labeled SPF 50. Another common rating is "50+", which means the product's SPF rating is higher than 50. This also saves the time consuming process of individually labeling a product SPF 60, SPF 65, SPF 70, and so on. With a rating of 50, most consumers are aware that the item offers a lot more protection than regular SPF 15.
If you feel you're prone to burning easily, then you'll want to look into getting a sunscreen with SPF 50 or even protective clothing that is labeled with SPF rating for your sun care needs.
