Why sunscreen is important...
Why Sunscreen is Important… Exposure to the sun’s rays is the #1 cause of skin ageing via oxidative stress and inflammation.
Sunlight consists of two types of harmful rays that reach the earth—UVA and UVB—both ultimately lead to premature ageing, wrinkles, and skin cancer development.
UVA rays (or ageing rays) can prematurely age your skin, causing wrinkles and age spots, and can pass through window glass.
UVB rays (or burning rays) are the primary cause of sunburn and are blocked by window glass.
But did you know that photoaging mainly results from daily exposure to low doses of UV radiation, which does not cause visible changes at the time of exposure but leads to greater biological changes over time.
In fact, 80% of facial ageing is believed to be due to daily, chronic sun exposure, what is known as incidental sun exposure from everyday activities—walking the dog, retrieving mail, driving in the car, etc.
Sunscreen formulations generally combine several ingredients that help prevent the sun’s UV rays from reaching the skin.
A broad-spectrum sunscreen protects you from both UVA and UVB rays. SPF stands for Sun Protection Factor. SPF is a measurement of how much protection a sunscreen has against sunburn. Applying sunscreen with an SPF of 15, for example, means that it will take 15 times longer for your skin to burn than it would without sunscreen.
