Wearing an SPF benefits your health in several ways. By protecting you from harmful radiation from the sun, it reduces your risk for skin cancer, premature aging and sunburns. It is something everybody should use all year round. Even if it isn’t a sunny day outside, the sun is still around.
The skin uses sunlight to help manufacture vitamin D, which is important for normal bone formation. But sometimes it’s ultraviolet light that can be very detrimental.
Sun exposure is responsible for the majority of the visible aging of your skin—far more than all other factors combined. Yes, UV rays from the sun are the primary cause of many things. Such as wrinkles, pigmentation, sun spots, reduced skin elasticity, the degradation of skin texture, and other signs of skin aging. Scientific estimates have shown that up to 80-90% of how young or old you look for your age is due to how much sun exposure you’ve experienced.
People who do not have much melanin and burn easily when in the sun should protect themselves by covering up sensitive areas, limiting their total exposure time, wearing sun block and limiting their sun exposure between the hours of 10am and 2pm. The time in between is when the sun is at its strongest and when the most damage can be made to the skin.
