Here are some quick facts about sunscreen and cancer that may help you understand the importance of the application and its use. “Broad spectrum” protection means your skin is protected from UVA and UVB rays.
Both of these types of rays are damaging to your collagen: UVA is a deeper ray that is the major cause of wrinkling and aging, and may cause skin cancer, while UVB rays are actually more damaging, is more potent in producing sunburns, and is the main cause of squamous cell cancer, basal cell cancer, and melanoma.
It is imperative when purchasing sunscreen to make sure that it contain either Zinc, or Titanium Dioxide. Sunscreen needs to be applied every day, because the sun’s rays are so powerful they can go through your windows, and even on cloudy days, the rays are harmful. When applying sunscreen, it is best to visualize a shot glass, and that’s how much you should use for your whole body.
Make sure to apply it at least fifteen minutes before going in the sun, and try to avoid being out in the sun between 10am-4pm. The last thing to remember (and the most important!) is to re-apply every two hours.
