Sunscreens protect your skin by blocking or absorbing the sun’s rays. Depending on the active ingredients in the sunscreen you use, you will protect yourself from the burning ultraviolet B (UVB) rays and the more penetrating ultraviolet A (UVA) rays.
The growing awareness of UVA’s destructive power is especially disturbing because since sunscreens were invented we have has the ability to protect ourselves against the burning UVB rays. That, obviously is a good thing. However, the downside is that since we’re less likely to burn, there is no warning sign that we’ve gotten too much sun. We could stay at the beach or on the golf course much longer than we might have in the days before sunscreens, exposing our skin to huge doses of UVA. Today we have broad-spectrum sunscreens that protect against both UVA and UVB rays.
Tip: Always wear a moisturizer with SPF.
