Spring is here, and summer is around the corner. As the weather gets warmer, more and more people will be spending an increased amount of time outside. Please don’t forget to wear sunscreen!
Sunrays expose our bodies to ultraviolet radiation. The 2 main types are UVA and UVB.
Radiation known as UVA is mostly responsible for aging of the skin and some cancer risk. UVB causes sunburns and carries a higher skin cancer risk.
It is important to use sunscreen that protects against both UVA and UVB rays! A minimum SPF of 15-30 is recommended. An SPF of 15 absorbs about 93% of UVB rays, SPF 30 absorbs about 97% of UVB rays, and SPF 50 absorbs 98% of UVB rays.
