No. Some sunscreens protect against only one type of ultraviolet radiation: ultraviolet-B (UVB). Others protect against both types of ultraviolet radiation that reach earth’s atmosphere from the sun: ultraviolet-B and ultraviolet-A (UVA). Sunscreens that protect against both UVA and UVB, and are thus classified as “broad spectrum” are recommended for everyone.
