What is the difference between the rays from the sun and do they do the same thing for our skin?
UVA rays are long, they will penetrate window glass and they are out every day, all year round.
UVA rays will penetrate the skin into the deeper layers (the leather skin) and they will create deep wrinkles.
UVB rays are shorter and at the same time the rays that will give your sunburns.
Have a great day!
