Exposure to UV radiation causes long-term skin damage, such as wrinkles, premature aging, and even skin cancer. As such, applying sunscreen is essential in keeping your skin protected.
Since UVC radiation is typically blocked by the earth's atmosphere, sunscreens on the market usually focus on blocking UVA and UVB radiation.
A sunscreen functions like a mirror that sits on your skin's surface and reflects UV rays. Therefore, it is crucial that sunscreen product testing is performed to determine not only the SPF value but also the active ingredients that you leave sitting on your skin for long periods of time.
