    Sun protection
    (0) Sun protection
    Apply sunblock at least half an hour before going outdoors and you should reapply sunblock every two hours, even for those with high SPF levels. Cosmetic products with built-in SPF may not provide sufficient sun protection, unless used in large amount. Thus, they should not be used alone and should be used together with a sunblock. Up to 80% of the sun’s ultraviolet (UV) rays pass through clouds. UVA rays are able to pass through clouds or window glass to reach your skin. Hence, it is important to apply sunblock regardless of the weather. SPF is a measure of how well a sunblock will protect the skin from ultraviolet B (UVB) rays, the type of radiation that causes sunburn and can contribute to the risk for skin cancer. Although higher SPF values do offer better protection against UVB, UVB protection alone is insufficient.
