UVB rays are the main reason behind a sunburn that comes from the solar. The SPF in your sunscreen product primarily describes its safety in opposition to these UVB rays.  UVB ray depth varies through the 12 months and in line with the place you’re on the planet.  Because of this that you must know when the UVB rays are most intense to grasp your sunburn danger. UVB rays are most intense:

  • through the center of the day between 10 am and 3pm
