What is the difference between UVA and UVB?

Understanding the difference between UVA and UVB can help you better understand why broad spectrum protection is so important.


What are UVA rays?

This stands for Ultraviolet A, and can be more easily remembered as “UV Aging rays” because they are the cause of long term skin damage & photo-aging. In other words, they cause premature ageing, wrinkles and sun spots.

What are UVB rays?

This stands for Ultraviolet B and are often referred to as “UV Burning rays” because they are the cause of sunburn. Unlike UVA, they have different strengths year round. UVB rays are the common cause of most skin cancers, which is why UVB protection is so important.

What about UBC rays?

UBC stands for Ultraviolet C. While it is the strongest and the most deadly of solar rays, our ozone layer stops these from reaching Earth.

How do I keep myself safe from all the different kinds of UV light?

Using a broad spectrum sunscreen that is specifically designed to block the effects of both UVA and UVB, and ensuring you are applying your sunscreen correctly, and reapplying appropriately, is the best way to keep your skin safe and reduce your skin cancer risk.
