What is UVA and what is UVB? The sun emits two types of ultraviolet (UV) radiation that reach our skin: ultraviolet A (UVA) and ultraviolet B (UVB). So if you are wondering what does UVA stand for or what does UVB stand for, they stand for ultraviolet A and ultraviolet B.
Without question, daily, consistent use of a broad-spectrum SPF 30 or greater 365 days a year, rain or shine, is the best way to preserve the health of your skin and reduce the risk of early skin ageing (fine lines, uneven skin tone, and loss of radiance) and even skin cancer.
